Bit Operations using Macros

Code

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

// Define bitwise macros here
#define set_bit_2_7(x) (x | (1<<2) | (1<<7))
#define clear_3(x) (x & ~(1<<3))
#define toggle_5(x) (x ^ (1<<5))
uint8_t modify_register(uint8_t reg) {
    reg = set_bit_2_7(reg);
    reg = clear_3(reg);
    reg = toggle_5(reg);
    return reg;
}

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