Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    uint8_t res = reg;
    res |= 1 << 2;
    res |= 1 << 7;
    res &= ~(1 << 3);
    res ^= 1 << 5;
    return res;
}

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