Bit Operations using Macros

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

// Define bitwise macros here
#define setbit(reg) reg|=(1<<2)|(1<<7)
#define clearbit(reg) reg&=~(1<<3)
#define togglebit(reg) reg^=(1<<5)
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    setbit(reg);
    clearbit(reg);
    togglebit(reg);
    return reg;
}

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