Question:

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

 

C Code:

#include <stdio.h>

void main()
{
  int i = 0;
  int sum = 0;
  while(i < 1000)
  {
    if(0 == i%3)
    {
      sum += i;
    }
    else if(0 == i%5)
    {
      sum += i;
    }
    i++;
  }
  printf("%d\n",sum);
}

 

Answer:
