【C語言】秀出數值的二進位表示

#include <stdio.h>

void showBinary(int value, int size) {
   int i ;
  
   for(i=(size<<3)-1 ; i>=0 ; i--)
       (value & (1<<i) ) ? putchar('1') : putchar('0') ;
}

int main() {
   int i=5 ;
   char j = 15 ;
  
   //example1: show int type, value is 5
   showBinary(i, sizeof(i)) ;
   putchar('\n') ;
   //example2: show char type, value is 15
   showBinary(j, sizeof(j)) ;
  
   getchar() ;
   return 0 ;
}
