modulo

[CJC0117]

Can someone please help me with this:

#include<cstdlib>
#include<iostream>
int main()
{
    int i;
    for(i=1;i<6;i++)
    {
        if(i%5!=0);
            std::cout<<i<<" "<<i%5<<std::endl;
    }
    system("pause");
    return 0;
}

Why does the console window show this:

1 1
2 2
3 3
4 4
5 0

Since the remainder of 5/5 is 0, 5 0 shouldn't be printed out, right?

Just a guess, but if you put parenthesis around i%5, it might work.

I already tried. Doesn't work. Neither does this:

#include<cstdlib>
#include<iostream>
int main()
{
    int i;
    i=5%5;
    if(i!=0);
        std::cout<<i;
    system("pause");
    return 0;
}

The output is 0. Doesn't make any sense to me.

Unless you are a complete beginner with one of your first programs, you are about to feel really stupid.

Semicolons mark the end of a statement. "if(anything);" will be completely disregarded.

lol, yeah I do feel stupid now. I'm not a complete beginner. Just made a very dumb mistake. Thanks!

I figured you weren't, just wanted to make sure nobody was left out. Everyone makes those mistakes.
