Bit Operations using Macros

Code

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

// Define bitwise macros here
#define set 2
#define set1 7
#define  clear 3 
#define toggle 5 

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= (1 << set);
     reg |= (1 << set1);
     reg &= ~(1 << clear);
     reg ^= (1 << toggle);     
    return reg;
}

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