Given an int variable n that has already been initialized to a positive value and, in addition, int variables k and total that have already been declared use a while loop to compute the sum of the cubes of the first n whole numbers.

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variables

   int n=5;

   int k,total=0;

   int copy=n;

   // while loop to calculate cubes

   while(n)

   {

       // find cube

       k=n*n*n;

       // find total

       total=total+k;

       // decrease n

       n--;

   }

   // print sum of cubes of first n whole numbers

   cout<<"Sum of cube of first "<<copy<<" numbers is "<<total<<endl;

return 0;

}

Explanation:

Declare three  variables n, k and total. initialize n with 5.In the while loop, calculate cube of n then add it to total.Then decrease the n by 1.While loop run until n becomes 0.After the while loop,total will have the sum of cubes of first n whole numbers.

Output:

Sum of cube of first 5 numbers is 225

this seems to be in the wrong category. but i'll take some free points my dude

posting this in wrong category will result in people seeing it who won't know the answer.
