Question

As title stated, I’m writing function taking 2 boolean as parameters but don’t know what is the best way to do! What are your suggestions?

Answer 1

Using two int values should work fine:

void func(int x, int y)
{
   if(x) // x is non-zero
   {
      // do something
   }
   if(y) // z is non-zero
   {
      // do something
   }
}

func(0, 1); // x is false, y is true

You could #define true and false to be something like 1 and 0:

#define FALSE 0
#define TRUE 1

func(FALSE, TRUE);
