Why is a condition like (0 < a < 5) always true?

Question

I implemented the following program in C

    #include 
    int main() 
    {
       int a  = 10 ; 
       if(0 < a < 5) 
       {
               


        

Answer 1

  if(x

It actually is valid syntax, but it doesn't do what you want.

Realize that x returns a bool, i.e. true or false. You then compare it against whatever value "z" has. So the intention of "x" looks wrong.

It can be:

if(x < y && y < z)
