Bit Operations using Macros

Code

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

// Define bitwise macros here
#define BIT_2  (2)
#define BIT_3  (3)
#define BIT_5  (5)
#define BIT_7  (7)

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= (1 << BIT_2);
    reg |= (1 << BIT_7);
    reg &= ~(1 << BIT_3);
    reg ^= (1 << BIT_5);
    return reg;
}

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