Compound condition in C: if (0.0 < a < 1.0)

Question

I recently noticed that the following expression compiles in my compiler (Clang):

float a;
if (0.0 < a < 1.0) { ... }

Does this do wh

Answer 1

Maybe we can think in this way(just for fun):

if(0.0 

==>

if((0.0 

think :

if 0.0 < a == true, then (true <1.0) == false!

else if 0.0 < a == false ,then (false <1.0) == true!

So I can translate if(0.0 to if(!(0.0

Interesting , right?
