Bit Operations using Macros

#include <stdio.h>

// Define bitwise macros here
#define set 132u
#define clear  3
#define toggle  5

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= set;
    reg &= ~(1 << clear);
    reg ^= (1 << toggle);

}

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