Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_2_7(x) (x | 0b10000100)
#define CLEAR_3(x) (x & 0b11110111)
#define TOGGLE_5(x) (x ^ 0b00100000)

uint8_t modify_register(uint8_t reg) {
    return TOGGLE_5(CLEAR_3(SET_2_7(reg)));
}

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