if

The if statement is for flow control.

int i = 7;

if ( i > 10 ) {
    printf( 'i > 10' );
}

You can also do:

if ( i > 10 )
    printf( 'i > 10' );

But don't, because when you add another result:

if ( i > 10 )
    printf( 'i > 10' );
    call_some_func();

Even though it's indented, call_some_func() is always executed,
regardless of the if
