Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_BITS 0x84
#define CLEAR_BITS 0x08
#define TOGGLE_BITS 0x20
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= SET_BITS;
    reg &= ~CLEAR_BITS;
    reg ^= TOGGLE_BITS;
    return reg;
}

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