Modulus operator: Why does this output to 18?

[Siz8AqkS]

#include <iostream>
using namespace std;
int main ()
{
    int c;
    c=(3%4)*6;
    cout<<c;
    return 0;
}

Do you know what 3%4 means and what value it gives?

[Siz8AqkS]

I don't know what it means but from the output its value is 3.

[Peter87]

3%4 gives the remainder from the division 3/4.

If you have a%b it gives the value of a-(a/b)*b.
