Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET0   2
#define SET1   7
#define CLEAR  3
#define TOGGLE 5 

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= (1<<SET0) | (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;
}
