The new software organization requires a new point of sale and stock control system for their many stores throughout Pakistan to replace their aging mini-based systems.
A sales assistant will be able to process an order by entering product numbers and required quantities into the system. The system will display a description, price, and available stock. In-stock products will normally be collected immediately by the customer from the store but may be selected for delivery to the customer's home address for which there will be a charge. If stock is not available, the sales assistant will be able to create a backorder for the product from a regional warehouse. The products will then either be delivered directly from the regional warehouse to the customer's home address, or the store for collection by the customer. The system will allow products to be paid for by cash or credit card. Credit card transactions will be validated via an online card transaction system. The system will produce a receipt. Order details for in-stock products will be printed in the warehouse including the bin reference, quantity, product number, and description. These will be collected by the sales assistant and given to the customer. The sales assistant will be able to make refunds, provided a valid receipt is produced. The sales assistant will also be able to check stock and pricing without creating an order and progress orders that have been created for delivery.

Answer:

How to implement a stack in C using an array?

A stack is a linear data structure that follows the Last in, First out principle (i.e. the last added elements are removed first).

This abstract data type​ can be implemented in C in multiple ways. One such way is by using an array.

​Pro of using an array:

No extra memory required to store the pointers.

Con of using an array:

The size of the stack is pre-set so it cannot increase or decrease.

If a system contains 1,000 disk drives, each of which has a 750,000- hour MTBF, which of the following best describes how often a drive failure will occur in that disk farm:

a. once per thousand years
b. once per century, once per decade
c. once per year, once per month
d. once per week
e. once per day
f. once per hour
g. once per minute
h. once per second

Answers

Answer:

once per month

Explanation:

The correct answer is - once per month

Reason -

Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs

So,

750/24 = 31.25 days

⇒ approximately one in a month.

Write a function that takes number between 1 and 7 as a parameter and prints out the corresponding number as a string. For example, if the parameter is 1, your function should print out one. If the parameter is 2, your function should print out two, etc. If the parameter is not between 1 and 7, the function should print an appropriate error message. In your file, you should include a main() that allows the user to enter a number and calls your function to demonstrate that it works.

Answers

Answer:

The program in C++ is as follows:

#include<iostream>

using namespace std;

void changenum(int num){

   string nums[7] = {"One","Two","Three","Four","Five","Six","Seven"};

   if(num >7 || num < 1){

       cout<<"Out of range";

   }

   else{

       cout<<nums[num-1];    }

}

int main(){

   int num;

   cout<<"Number: ";

   cin>>num;

   changenum(num);

   return 0;

}

Explanation:

The function begins here

void changenum(int num){

This initializesa string of numbers; one to seven

   string nums[7] = {"One","Two","Three","Four","Five","Six","Seven"};

If the number is less than 1 or greater than 7, it prints an out of range error

   if(num >7 || num < 1){

       cout<<"Out of range";

   }

If otherwise, the corresponding number is printed

   else{

       cout<<nums[num-1];    }

}

The main begins here

int main(){

This declares num as integer

   int num;

Prompt the user for input

   cout<<"Number: ";

Get input from the user

   cin>>num;

Pass the input to the function

   changenum(num);

   return 0;

}

The program you wrote in Stacks 1 is incomplete. Without a destructor it creates a memory leak. A destructor has been defined in this program but it is incorrect. To visualize how the destructor works, a cout statement has been added. Fix the errors, including the cout statement, to display the value in each node of the stack before releasing the memory.
Write a loop in main() to enter an unknown number of positive integers. The loop stops when you enter 0 or a negative number. As you are entering integers, they are to be pushed onto a stack.
Ex.: If the user enters '10 20 30 -1` the output (from the destructor) should be:
30 - deleted!
20 - deleted!
10 - deleted!
Empty stack!
Ex.: If the user enters '-1` the output should be:
Empty stack!
This is the code:
#include
using namespace std;
class Stack_int
{
private:
// Structure for the stack nodes
struct StackNode {
int value; // Value in the node
StackNode *next; // Pointer to next node
};
StackNode *top; // Pointer to the stack top
int length; // Number of nodes
public:
Stack_int(){ top = NULL; length = 0; } //Constructor
~Stack_int(); // Destructor
// Stack operations
// bool isEmpty();
bool push(int);
// int pop();
// int peek();
// int getLength();

Consider the following examples, in whichthe array arrcontains {4, 1, 3, 6, 2, 9}.The call divBySum(arr, 3) will return 18,which is the sum of 3, 6, and 9,since those are the only integers in arr that aredivisible by 3.The call divBySum(arr, 5) will return 0,since none of the integers in arr are divisibleby 5.Complete the divBySum method using anenhanced for loop. Assume that arr isproperly declared and initialized.

The hexadecimal equivalent

of 22210 is DE

The binary equivalent of

D7 is 11010011

The decimal equivalent of

1316 is 19.

True

False

Answers

Answer:

[tex](a)\ 222_{10} = DE_{16}[/tex] --- True

[tex](b)\ D7_{16} = 11010011_2[/tex] --- False

[tex](c)\ 13_{16} = 19_{10}[/tex] --- True

Explanation:

Required

Determine if the statements are true or not.

[tex](a)\ 222_{10} = DE_{16}[/tex]

To do this, we convert DE from base 16 to base 10 using product rule.

So, we have:

[tex]DE_{16} = D * 16^1 + E * 16^0[/tex]

In hexadecimal.

[tex]D =13 \\E = 14[/tex]

So, we have:

[tex]DE_{16} = 13 * 16^1 + 14 * 16^0[/tex]

[tex]DE_{16} = 222_{10}[/tex]

Hence:

(a) is true

[tex](b)\ D7_{16} = 11010011_2[/tex]

First, convert D7 to base 10 using product rule

[tex]D7_{16} = D * 16^1 + 7 * 16^0[/tex]

[tex]D = 13[/tex]

So, we have:

[tex]D7_{16} = 13 * 16^1 + 7 * 16^0[/tex]

[tex]D7_{16} = 215_{10}[/tex]

Next convert 215 to base 2, using division rule

[tex]215 / 2 = 107 R 1[/tex]

[tex]107/2 =53 R 1[/tex]

[tex]53/2 =26 R1[/tex]

[tex]26/2 = 13 R 0[/tex]

[tex]13/2 = 6 R 1[/tex]

[tex]6/2 = 3 R 0[/tex]

[tex]3/2 = 1 R 1[/tex]

[tex]1/2 = 0 R1[/tex]

Write the remainders from bottom to top.

[tex]D7_{16} = 11010111_2[/tex]

Hence (b) is false

[tex](c)\ 13_{16} = 19_{10}[/tex]

Convert 13 to base 10 using product rule

[tex]13_{16} = 1 * 16^1 + 3 * 16^0[/tex]

[tex]13_{16} = 19[/tex]

Hence; (c) is true

Which of the following statements are true about the code shown below in the class named Quiz? (Select all that apply.)

public class Quiz {
public static void printOdd(int n) {
for(int i = 0; i < n; i++){
if(i % 2 != 0)
System.out.println(i);
else
System.out.println(i+1);
}
}

public static void main(String arg[]) {
printOdd(5);
}
}

a. A value of 5 will be substituted for the parameter during the execution of the printOdd method.
b. This method will print a list of all even numbers less than n.
c. This method when executed as called by main will print out 5 lines of output.
d. This method when executed as called by main will print out 1 line of output.
e. A value of 5 is being returned to main from the printOdd method after execution.

Answers

Answer:

a. and c.

Explanation:

The snippet of code provided will print out all of the odd numbers between 0 and the value passed as a parameter. If a number is even, it will add 1 to the even number and print out the new value. Therefore, there will be a total of outputs as the number passed as an argument. For example, this code will output a total of 5 lines of output. Therefore, the statements that would be true in this question would be the following...

a. A value of 5 will be substituted for the parameter during the execution of the printOdd method.

c. This method when executed as called by main will print out 5 lines of output.

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

#include <iomanip>

using namespace std;

int main(){

   int cars;

   cin>>cars;

   double weights[cars];

   double total = 0;

   for(int i = 0; i<cars;i++){

       cin>>weights[i];

       total+=weights[i];    }

   double avg = total/cars;

   for(int i = 0; i<cars;i++){

       cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl;    }

   return 0;

}

Explanation:

This declares the number of cars as integers

   int cars;

This gets input for the number of cars

   cin>>cars;

This declares the weight of the cars as an array of double datatype

   double weights[cars];

This initializes the total weights to 0

   double total = 0;

This iterates through the number of cars

   for(int i = 0; i<cars;i++){

This gets input for each weight

       cin>>weights[i];

This adds up the total weight

       total+=weights[i];    }

This calculates the average weights

   double avg = total/cars;

This iterates through the number of cars

   for(int i = 0; i<cars;i++){

This prints how much weight to be added or subtracted

       cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl;    }
