Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SETBIT27    (1 << 7 | 1 << 2)
#define CLR3        ~(1 << 3)
#define TOG5        (1 << 5); 
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= SETBIT27; 
    reg &= CLR3; 
    reg ^= TOG5; 
    return reg;
}

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