Bit Operations using Macros

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

// Define bitwise macros here
#define Set(reg) reg |= (1 << 2) | (1 << 7)
#define Clear(reg) reg &= ~(1 << 3)
#define Toggle(reg) reg ^= (1 << 5)

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    Set(reg);
    Clear(reg);
    Toggle(reg);
    return reg;
}

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