Casting int to bool in C/C++

Question

I know that in C and C++, when casting bools to ints, (int)true == 1 and (int)false == 0. I\'m wondering about casting in the reverse direction...<

Answer 1

There some kind of old school 'Marxismic' way to the cast int -> bool without C4800 warnings of Microsoft's cl compiler - is to use negation of negation.

int  i  = 0;
bool bi = !!i;

int  j  = 1;
bool bj = !!j;
