i got this signature
and inside it doesCode:void what(char *str, int flag){
where flag is 0Code:what(str-1, !flag);
so whats !0 means
or what !number is in terms of integer??
(i know it from the if expressions and it has nothing to do with integers)

If number is 0, it results in 1, otherwise it results in 0.

!0 means it's true(any non-zero quantity).

so !8 is 0
and !0 is 1
i think you are mistaken because
if we say differs false(0)
it could be any number that differs 0
4 ,8, 19
etc..
how do you know its 1
Because that is how operator! works in C.

!x is basically short for
(x) == 0 ? 1 : 0
Any non-zero value is regarded as 'true', but the result of any boolean expression will always be 0 or 1

Code:#include <stdio.h> int main() { int x; x=!0; printf("%d",x);// outputs 1 }
