Need help with Function.

**kishorepalle** · 11-15-2004

Hello guys, I am doing a C Project.

The thing where I am stuck at is, Comparing the returned value of a function with a zero. I don't know if it can be done like by comparing the function name with a zero directly. If we cannot do that how can we catch the returned value into a var (so that we can compare this to a zero).

It will be really great if anyone can provide some idea if I am
doing anything faulty.

Best Regards,
Kishore

foo();
Calls a function called foo

if ( bar() == 0 )
Calls a function called bar, and compares it's return result with 0

Otherwise, you use the return value just like you assign any type:

Code:

int bar( void )
{
    return 1;
}

int main( void )
{
    int foo;

    foo = bar( );
    return 0;
}
