The not macro, which is part of <iso646.h>, is a convenient object-like macro name that expands to the ! operator. The macro was added in Normative Addendum 1 in an effort to provide support for international character sets that might not have the ! symbols.
Synopsis[edit]
#include <iso646.h>
#define not !
Description[edit]
The not object-like macro expands to the ! operator.
Example[edit]
#include <iso646.h>
int main ()
{
if (not(2 == 1))
return 1;
return 0;
}
