Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET(num,pos) num|(1<<pos)
#define TOGGLE(num,pos) num^(1<<pos)
#define Clear(num,pos) num&= ~(1<<pos)
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
   reg = SET(reg,2);
   reg = SET(reg,7);
   reg = Clear(reg,3);
   reg = TOGGLE(reg,5);
    return reg;
}

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