Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_BITS (uint8_t)132    // 1000 0100
#define CLEAR_BIT (uint8_t)8     // 0000 1000
#define TOGGLE_BIT (uint8_t)32   // 0010 0000

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    //Set Bits
    reg |= SET_BITS;
    //Clear Bits
    reg &= (~CLEAR_BIT);
    //Toggle Bits
    reg ^= TOGGLE_BIT;
    return reg;
}

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