Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a for loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. thus if n equals 4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into total. use no variables other than n, k, and total.

The code is in Java.

It uses for loop to calculate the sum of the cubes of the first n numbers.

Recall that loops are used when there is a repetition. In the algorithm, we repeat the process of taking the cube of a number and adding it to the sum.

Comments are used to explain each line of code

//Main.java

public class Main

{

public static void main(String[] args) {

 //declare the variables

 int n = 4, k, total = 0;

 //for loop that iterates n times

 //add the cubes of the numbers to the total (cumulative sum)

 for (k=1; k<=n; k++){

     total += (k * k * k);

 }

 //print the total

 System.out.println(total);

}

}

Explanation &

We do not know which language you are using, so a pseudocode will be given, it will be similar to java or C/C++.  For other languages, you can adapt to the syntax of the target language.

int n=5;

//

total = 0  // initialize  variable to store total value, already declaired.

// k will be used as a dummy variable, already declared

for (k=1; k<=n; k++){

   total+=k*k*k;  // k*k*k works for almost all languages.  adapt as needed

   }

print(n, total)
