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 do…while 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.

LANGUAGE: C++

CHALLENGE:

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 do…while 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.

SOLUTION:

total=0;
k=0;
do{
    total+=k*k*k;
    k++;
}
while (k<=n);
