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 counting 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. Do NOT modify n.

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 counting 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. Do NOT modify n.

SOLUTION:


k = 0
total = 0
Do While (k <= n)
    total = (total + (k*k*k))
    k += 1
Loop
