Write a C program to prform simple C aritlimetic calculations. The user is to enter a simple expression(integer operaior integer) such as 15+30=45. The program is to exlract the 2 operands and the operator, perform the indicated calculation and display the result. For examole15 + 30 = 45. Operators should includc t, -, * , l, and %'.Operands are prcsitive integers, no sign. Use getchar to input the cxpression. Allow for variable spacing before the first operand and between operators and operands.
Answer:
Here is the C program:
#include <stdio.h> //to use input output functions
//functions prototype
unsigned int mod(unsigned int a, unsigned int b);
unsigned int mul(unsigned int a, unsigned int b);
unsigned int sub( unsigned int a,unsigned int b);
float divide(unsigned int a,unsigned int b);
unsigned int add( unsigned int a,unsigned int b);
int main() { //start of main method
unsigned int a, b; //declare variables to store the operands
char d; //declare variable to store the operator
printf("Enter an operator: "); //prompts user to enter an operator
scanf("%c",&d); //reads the operator from use
getchar(); //gets a character
while (d!='q') { //keeps iterating until user enters q to quit
printf("Enter 1st operand: "); //prompts user to enter first operand
scanf("%d",&a); //reads first operand from user
getchar(); //reads character
printf("Enter 2nd operand: "); //prompts user to enter second operand
scanf("%d",&b); //reads second operand from user
getchar();
if (d=='%') { //if the character of operator is a mod
printf("%d",a); //prints operand 1
putchar(d); //displays operator
printf("%d",b); //displays operand 2
printf(" = "); //displays =
mod(a,b); } //displays computed modulo of two input operands
if (d=='*') //if the input character is for multiplication operator
{printf("%d",a); //prints operand 1
putchar(d); //displays operator
printf("%d",b); //displays operand 2
printf(" = "); //displays =
mul(a,b); } //displays computed multiplication
if (d=='+') { //if the input character is for addition operator
printf("%d",a); //prints operand 1
putchar(d); //displays operator
printf("%d",b); //displays operand 2
printf(" = "); // displays =
add(a,b); } //displays computed addition
if (d=='/') { //if the input character is for division operator
printf("%d",a); // prints operand 1
putchar(d); //displays operator
printf("%d",b); //displays operand 2
printf(" = "); //displays =
divide(a,b); } //displays computed division
if (d=='-') { //if the input character is for subtraction operator
printf("%d",a); //prints operand 1
putchar(d); //displays operator
printf("%d",b); // displays operand 2
printf(" = "); //displays =
sub(a,b); } //displays computed subtraction
printf("Enter an operator: "); //asks again to enter an operator
scanf("%c",&d); //reads operator from user
getchar(); } } //gets character
unsigned int mod( unsigned int a, unsigned int b){ //function to compute modulo of two integers with no sign
int c = a%b; //computes mod
printf("%d",c); } //displays mod result
unsigned int add(unsigned int a, unsigned int b){ // function to compute addition of two integers
int c = a+b; //computes addition
printf("%d\n",c); } //displays result of addition
unsigned int mul(unsigned int a, unsigned int b){ //function to compute multiplication of two integers
int c = a*b; //multiplies two integers
printf("%d\n",c); } //displays result of multiplication
float divide(unsigned int a, unsigned int b){ //function to compute division of two integers
float c = a/b; //divides two integers and stores result in floating point variable c
printf("%f\n",c); } //displays result of division
unsigned int sub(unsigned int a, unsigned int b){ //function to compute subtraction of two integers
int c = a-b; //subtracts two integers
printf("%d\n",c); } //displays result of subtraction
Explanation:
The program is well explained in the comments mentioned with each line of the program. The program uses while loop that keeps asking user to select an operator and two operands to perform arithmetic calculations. The if conditions are used to check what arithmetic calculation is to be performed based on user choice of operand and calls the relevant function to perform calculation. There are five functions that perform addition, modulo, subtraction, division and multiplication and display the result of computation. The screenshot of output is attached.
Adjust list by normalizing When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one.

The program written in python 3 deducts the least from a list of user given integers and prints the output. The program goes thus :
len_input = int(input())
#the number of inputs the user wishes to supply
vals = []
#initialize an empty list to accept the inputs
for i in range(1, len_input +1):
#use a loop to accept the user inputs
num = int(input())
#allow users to take in the inputs
vals.append(num)
#append each value to the list
least =min(vals)
#using the min function, obtain the lowest value from the list
output_vals = []
#initialize an empty list to hold the normalized values
for i in range(len_input):
#loop using a for loop
diff = vals[i] - least
#deduct the minimum value from each element in the list
output_vals.append(diff)
#append the values to the new list.
print(output_vals)
#display the output

Remove gray from RGB Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part.
Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main() { //start of main method
int red,green,blue,smallest; //declare variables to store integer values of red,green, blue and to store the smallest value
cout<<"Enter value for red: "; //prompts user to enter value for red
cin>>red; //reads value for red from user
cout<<"Enter value for green: "; //prompts user to enter value for green
cin>>green; //reads value for green from user
cout<<"Enter value for blue: "; //prompts user to enter value for blue
cin>>blue; //reads value for blue from user
//computes the smallest value
if(red<green && red<blue) //if red value is less than green and blue values
smallest=red; //red is the smallest so assign value of red to smallest
else if(green<blue) //if green value is less than blue value
smallest=green; //green is the smallest so assign value of green to smallest
else //this means blue is the smallest
smallest=blue; //assign value of blue to smallest
//removes gray part by subtracting smallest from rgb
red=red-smallest; //subtract smallest from red
green=green-smallest; //subtract smallest from green
blue=blue-smallest; //subtract smallest from blue
cout<<"red after removing gray part: "<<red<<endl; //displays amount of red after removing gray
cout<<"green after removing gray part: "<<green<<endl; //displays amount of green after removing gray
cout<<"blue after removing gray part: "<<blue<<endl; } //displays amount of blue after removing gray
Explanation:
I will explain the program using an example.
Lets say user enter 130 as value for red, 50 for green and 130 for blue. So
red = 130
green = 50
blue = 130
First if condition if(red<green && red<blue) checks if value of red is less than green and blue. Since red=130 so this condition evaluate to false and the program moves to the else if part else if(green<blue) which checks if green is less than blue. This condition evaluates to true as green=50 and blue = 130 so green is less than blue. Hence the body of this else if executes which has the statement: smallest=green; so the smallest it set to green value.
smallest = 50
Now the statement: red=red-smallest; becomes:
red = 130 - 50
red = 80
the statement: green=green-smallest; becomes:
green = 50 - 50
green = 0
the statement: blue=blue-smallest; becomes:
blue = 130 - 50
blue = 80
So the output of the entire program is:
red after removing gray part: 80 green after removing gray part: 0 blue after removing gray part: 80
The screenshot of the program along with its output is attached.

Suppose one machine, A, executes a program with an average CPI of 1.9. Suppose another machine, B (with the same instruction set and an enhanced compiler), executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz. In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Answer:
the clock rate of the first machine need to be 1.7 GHz
Explanation:
Given:
CPI of A = 1.9
CPI of B = 1.1
machine, B executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz
To find:
In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Solution:
CPU execution time = Instruction Count * Cycles per Instruction/ clock rate
CPU execution time = (IC * CPI) / clock rate
(IC * CPI) (A) / clock rate(A) = (IC * CPI)B / clock rate(B)
(IC * 1.9) (A) / clock rate(A) = (IC * (1.1 * (1.0 - 0.20)))(B) / 800 * 10⁶ (B)
Notice that 0.20 is basically from 20% less instructions
(IC * 1.9) / clock rate = (IC * (1.1 * (1.0 - 0.20))) / 800 * 10⁶
(IC * 1.9) / clock rate = (IC*(1.1 * ( 0.8))/800 * 10⁶
(IC * 1.9) / clock rate = (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) / (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) (800 * 10⁶) / (IC * 0.88)
clock rate (A) = 1.9(800)(1000000) / 0.88
clock rate (A) = (1.9)(800000000) / 0.88
clock rate (A) = 1520000000 / 0.88
clock rate (A) = 1727272727.272727
clock rate (A) = 1.7 GHz

The government of a country wants to know how much inbound tourism (number of tourists visiting from other countries) is contributing to the country’s economic prosperity. The research firm hired to conduct this study surveys 10,000 residents on their favorite spots to visit in the country and how much money they spend on leisurely activities
a. How could the use of a sample like this threaten the value of the study’s outcomes?
b. How might the flawed sample affect the usefulness of the results?
Answer and Explanation:
A. The study by the research team may not reflect the purpose of the research which is to know how much inbound tourism is contributing to the economy. They are sampling the population on their favorite spots to visit( which may be too narrow here) and what their leisure activities are (which are not the only things tourists spend on). Also 10000 residents may be too small as a sample to reflect more accurate study outcome representative of the population.
2. A flawed sample which is a sampling error would not represent the population as the results from sample would contradict population results

They are very useful when it comes to visualization of values that are In a range of cells. Now if the bar is longer then the value we are visualizing is definitely higher. And if it is shorterr the value is lower. Several applications like excel has programmes that makes use of data bars especially for statistical purposes.
Create a class named Invoicing that includes three overloaded computeInvoice() methods for a book store: see pages 196 for examples… The 8% tax should be defined as a constant.
1. When computeInvoice() receives a single parameter, it represents the price of one book ordered. Add 8% tax and display the total due.
2. When computeInvoice() receives two parameters, they represent the price of a book and the quantity ordered. Multiply the two values, add 8% tax, and display the total due.
3. When computeInvoice() receives three parameters, they represent the price of a book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and display the total due.
Create a driver class named TestInvoice with a main() method that tests all three overloaded methods using the following data: Price $24.95 Price, $17.50, quantity 4, Price $10.00, quantity 6, coupon $20.00 Output printed to Eclipse Console:
Price $26.95
Price $76.95
Price $43.20
Answer:
Follows are the method to this question:
class Invoicing //defining a class Invoicing
{
public static final double Tax = 8.0; //defining static variable Tax that holds a value
public static double Total;//defining a double variable Total
public void computeInvoice(double p1)//defining method computeInvoice that take double parameter
{
Total = p1 + p1 * (Tax / 100);//defining double variable Total that holds Price value
System.out.printf("Price $%.2f\n" , Total);//print calculated value
}
public void computeInvoice(double p2, int q)//defining method computeInvoice that takes integer and double parameter
{
Total = p2 * q;//use Total variable that calculate Price with Tax
Total = Total + (Total * (Tax/ 100));//calculate taxes on Total
System.out.printf("Price $%.2f\n" , Total);//print calculated value
}
public void computeInvoice(double p3, int q, double c)//defining method computeInvoice that takes one integer and two-double parameter
{
Total = p3 * q;//use Total to calculate Total price
Total = Total - c;//remove coupon amount from Total amount
Total = Total + (Total * (Tax/ 100));//calculate taxes on Total
System.out.printf("Price $%.2f\n" , Total);//print calculated value
}
}
public class TestInvoice //defining Main class TestInvoice
{
public static void main(String[] ar)//defining main method
{
Invoicing obm = new Invoicing ();//creating Invoicing class object obm
obm.computeInvoice(24.95);//calling method computeInvoice
obm.computeInvoice(17.5, 4);//calling method computeInvoice
obm.computeInvoice(10, 6, 20);//calling method computeInvoice
}
}

Explanation:
In the above-given code, a class "Invoicing" is defined, inside the class two static double variable "Total and Tax" is defined, in which the Tax variable holds a value that is "8.0".
In class three same method, "computeInvoice" is used that accepts a different parameter for providing method overloading, which can be defined as follows:
In the first method, it accepts a single double parameter "p1", and inside the method, it uses the "Total" variable to calculate price value.In the second method, it accepts one integer and one double parameter "q and p2", and inside the method, it uses the "Total" variable is used to calculate the price with tax and print its value.In the third method, it accepts one integer and two double parameters "q, p3, and c", and inside the method, it uses the "Total" variable is used to calculate the price with tax and include tax and print its value.In the next step, the main class "TestInvoice" is defined inside the main method, Invoicing object is created and call its method.
