Use of increments little prob.

Question

Hi i have a problem with this program. Its not too complex, but frustrating. Here is the question......Write a complete c++ program to find the sum of first 5 odd numbers using while loop. Make sure to write an output statement to show the sum. Hint: Variable sum needs to be initialized to 0. Here is what I have so far

#include <iostream>
using namespace std; 
int main () 

{ 
    int x, b,c;
     x= 1;
     b=1;
     c=0;

    do 

    {

    x+=2;

    cout<<x<<endl;
}

    while (x<=5);

   {
          c= c +x;

          x++;
          cout<<x<<endl;




    system ("pause"); 

    return 0; 

Answer 1

Here's one way:

#include <iostream>
using namespace std; 
int main () 

{ 
    int x,b,c;
     x = 1;
     b = 1;
     c = 0;

    while (b <= 5) { 

       c = c + x;

       x+=2;
       b++;
    }
    cout<<x<<endl;

    system ("pause"); 

    return 0; 
}
