Bit Operations using Macros

Code

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

// Define bitwise macros here
#define set (1<<2)|(1<<7)
#define clear ~(1<<3)
#define toggle (1<<5)

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |=set;
    reg &=clear;
    reg ^=toggle;
    
    return reg;
}

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