Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) 
{
    //reg |= (1<<2);
    //reg |= (1<<7);
    //reg &= ~(1<<3);
    //reg ^= (1<<5);

    return ((((reg | (1<<2)) | (1<<7)) &~(1<<3)) ^ (1<<5));
}

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