Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_2 2
#define SET_7 7
#define CLEAR_3 3
#define TOGGLE_5 5


uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= (1 << SET_2) | (1 << SET_7);
    reg &= ~(1 << CLEAR_3);
    reg ^= (1 << TOGGLE_5);
    return reg;
}

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