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 while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. Use no variables other than n, k, and total and do not modify the value of n.
1 total = 0;
2 k = 0;
while(n >= k)
{
total = total + (n * n * n);
k++;
}
