Bit Operations using Macros

Code

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

// Define bitwise macros here
#define BIT2 (1 << 2)
#define BIT3 (1 << 3)
#define BIT5 (1 << 5)
#define BIT7 (1 << 7)


uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg |= (BIT2);
    reg |= (BIT7);
    reg &= ~(BIT3);
    reg ^= (BIT5);
    return reg;
}

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