Answer:
The program in Python is as follows:
n = int(input("n:"))
total = 0
for k in range(1,n+1):
total+=k**3
print(total)
Explanation:
This gets input for n
n = int(input("n:"))
This initializes total to 0
total = 0
This iterates from 1 to n
for k in range(1,n+1):
This adds up the cube of each digit
total+=k**3
This prints the calculated total
print(total)

Given the declaration: char a[] = "Hello"; char *p = a, *q; what operations are valid syntactically? Select all that apply. Group of answer choices q = &&a[0]; q = &&a; *q = *(&a[0]); q = &(*p);
Answer:
The valid operations are:
*q = *(&a[0]); and q = &(*p);
Explanation:
Given
The above declarations
Required
The valid operations
*q = *(&a[0]); and q = &(*p); are valid assignment operations.
However, q = &&a[0]; q = &&a; are invalid because:
The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.
Hence, *q = *(&a[0]); and q = &(*p); are valid
Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler

write short notes about monitor printer and speaker
Answer:
A computer monitor is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
Speakers receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.

1. Design pseudocode for a program that will permit a user to store exactly 75 numbers in an array. Create an array big enough to hold the numbers and store each number in the array as it's entered. Be sure to PROMPT the user for each number before it's entered. You do not need to initialize the array. HINTS: Make sure you use a named constant when you declare the array (the number inside the brackets should be a named constant that you declared before the array declaration.) Use a for loop (or while loop if you'd like) to get each number from the user. The module has an example of pseudocode very similar to this problem. You're free to use this pseudocode as you create your program. 2. Identify three advantages of arrays. For each advantage, write at least one complete sentence explaining why the advantage you listed is an advantage. More detail is better. You may use outside resources but be sure to CITE those resources using APA format.
Answer:
Question 1: The pseudocode is as follows:
int n = 70;
int intArray[n];
for(int i = 0; i< n; i++){
print("Input "+(i+1)+": ")
input intArray[i];
}
Question 2: Advantages of array
Indexing in arrays in easyIt can be used to store multiple values of the same typeIt can be used for 2 dimensional inputsExplanation:
Question 1
This declares and initializes the length of the array
int n = 70;
This declares the array
int intArray[n];
This iterates through the length of the array
for(int i = 0; i< n; i++){
This prompts the user for inputs
print("Input "+(i+1)+": ")
This gets input for each element of the array
input intArray[i];
}
Question 2
Indexing: Elements of the array can easily be accessed through the index of the element.
For instance, an element at index 2 of array intArray can be accessed using: intArray[2]
Multiple Values: This is illustrated in question 1 above where we used 1 array to collect input for 70 values.
2 dimensional inputs: Literally, this means that array can be used to represent matrices (that has rows and columns).
An illustration is:
intArray[2][2] = {[0,1],[3,5]}
The above array has 2 rows, 2 columns and 4 elements in total.

Horizontal Navigation List Styles
Go to the Horizontal Navigation List Styles section. Karen has added a second navigation list that she wants to display horizontally. For all list items within the horizontal navigation list, create a style rule that displays the items as blocks with a width of 12.5% floated on the left margin.
Here is my code:
/* Horizontal Navigation List Styles */
.horizontal li {
display: block;
width: 12.5%;
float: left;
}
It's coming through as just a line and I have no idea how to fix it, please help!
Answer:
Explanation:
The best way to do this would be to use the following line of code
clear: left;
This would make sure that there are no floating elements (li's in this scenario) on the left side of each element. Which in this navigation list would be each individual element, causing it to move each element underneath the previous element. Therefore the entire CSS code would be
.horizontal li {
display: block;
width: 12.5%;
float: left;
clear: left;
}

Create a method called letterGrade that will pass the student's average grade as a parameter and return a letter grade (char). Once passed, use an if..else if structure to determine whether the student has an A, B, C, D, or F. Return that letter grade. Use the standard grade scale: 90-100 (A), 80-89 (B), 70-79 (C), 60-69 (D), 0-59 (F).
Answer:
The method in Java is as follows:
public static char letterGrade(int average){
char grade =' ';
if(average>= 90 && average <=100){ grade ='A'; }
else if(average>= 80 && average <=89){ grade ='B'; }
else if(average>= 70 && average <=79){ grade ='C'; }
else if(average>= 60 && average <=69){ grade ='D'; }
else if(average>= 0 && average <=59){ grade ='F'; }
return grade;
}
Explanation:
This defines the method
public static char letterGrade(int average){
This initializes the grade to a blank
char grade =' ';
If average is between 90 and 100 (inclusive), grade is A
if(average>= 90 && average <=100){ grade ='A'; }
If average is between 80 and 89 (inclusive), grade is B
else if(average>= 80 && average <=89){ grade ='B'; }
If average is between 70 and 79 (inclusive), grade is C
else if(average>= 70 && average <=79){ grade ='C'; }
If average is between 60 and 69 (inclusive), grade is D
else if(average>= 60 && average <=69){ grade ='D'; }
If average is between 0 and 59 (inclusive), grade is F
else if(average>= 0 && average <=59){ grade ='F'; }
This returns the grade
return grade;
}

why absolute reference is used in spreadsheet
Absolute reference is used especially to keep the value or content of a column or row constant.
Explanation:Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.
In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.
i. relative referencing
ii. absolute referencing
iii. mixed referencing
Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.
Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.
Mixed reference is a hybrid of the relative and absolute references.
