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