c - What is wrong with the following macro usage? -


ispowerof(2) in main() causes expected ); error ...what wrong this?

#include<stdio.h>  #define ispowerof2(n)  (!(n & (n-1))  int main(){     int n,p;     clrscr();     printf("\nenter number checked:");     scanf("%d",&n);     ispowerof2(n);     printf("%d",p);  getch(); }

you're missing 1 more bracket:

#define ispowerof2(n)  (!(n & (n-1)))                                     ^

side note: if don't have use macro, use function instead.
