Question
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 .

Answer
# 1
total=0;
k=1;
do
{
total=total+k*k*k;
k++;
}while(k<=n)

Answer
# 2
total=0;
while(n>=1)
{
  total+=n*n*n;
  n--;
}

#include<conio.h>
#include<math.h>
main()
{
int n=3;
int k=1,total=0;
do
{
    total=total+(pow(k,3));
    k=k+1;

Given that two int variables, total and amount, have been declared, write a loop that reads integers into amount and adds all the non-negative values into total. The loop terminates when a value less than 0 is read into amount. Don't forget to initialize total to 0. Instructor's notes: This problem requires either a while or a do-while loop.  1

Given that two int variables, total and amount , have been declared, write a sequence of statements that: initializes total to 0 reads three values into amount , one at a time. After each value is read in to amount , it is added to the value in total (that is, total is incremented by the value in amount ). Instructor's notes: If you use a loop, it must be a for loop. And if you use a loop control variable for counting, you must declare it.  1
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 .  3
