Given three numbers A, B and X. Print the summation of numbers between A and B inclusive that are divisible by X.

#include<iostream>
using namespace std;
int main()
{
    int a,b,x,sum=0,i;
    cin>>a>>b>>x;
    for(i=a;i<=b;i++)
    {
        if(i%x == 0)
        {
            sum = sum+i;
        }
    }
    cout<<sum;
    return 0;
}
