Program crash while using if statement inside a for loop

Question

I am trying to give a shot at Project Euler problem 3 until codeblocks or whatever caused it pissed me off. This is my code, What is wrong with it? I guess more of a bug?

#include <iostream>
using namespace std;

int main()
{
    int x=0;

    for(int y=0;y<=10;y++)
    {
        if(13195%x==0)
        {
            cout<<"I don't know why the program crashes!";
        }
    }
}

-1 for blaming Codeblocks for your bug; *"A poor workman blames his tools."* — JBentley, Apr 17 '13 at 13:43
Sorry, It was frustrating as I had tried for almost about an hour :/ and its ends up being a stupid mistake. — Rohan Bojja, Apr 17 '13 at 18:08

You can't use a 0 as the second operand while doing / or %. What you're essentially saying is "Hey divide by 0 and give me the remainder." Please see the following:

Modulus operator divides it by zero and next finds the remainder, thus you will get divide by zero error

x must not be equal to 0 otherwise division by zero.

Just think how many zeroes in 13195?

x = 0. Dividing a number with zero will crash your code. Make sure x is not 0 before 13195 % x.

The operation A modulo B is defined as: the remainder of the division of A by B. In your code, you have B=0 which means you are trying to divide by zero.
