Question

Here is the code which compiles :

int select_object = 0;

if( select_object )  //condition returns an int
{

     printf("Hello");

}

if condition returns an int and not a boolean will the hello be printed ? When I tested this it printed hello.

Any idea why even for an int it executes the print statement.

THanks

Answer 1

Boolean logic

1 = True

0 = False

1 && 0 = False 0

1 && 1 = True 1

1 || 1 = True 1

1 || 0 = True 1

So the answer is for non-zero it is considered true, for 0 it is considered false. If your value (your int) returns 0 it won’t execute. If it returns a value that is not 0 it will execute.
