Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>

// Define bitwise macros here

 #define SET(reg) (reg & 247) 
 #define CLR(reg) ((reg | 132)) 
 #define TOG(reg) ((reg ^ 32)) 

uint8_t modify_register(uint8_t reg) {

     reg = SET(reg);
     reg = CLR(reg);
     reg = TOG(reg);
     return reg;
    // Apply operations in order
   
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", modify_register(reg));
    return 0;
}
