Bit Operations using Macros

Code

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

// Define bitwise macros here
#define Macro_bitwise(x) (1 << x)

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    uint8_t clear_3 = ~(Macro_bitwise(3));
    uint8_t toggle_5 = Macro_bitwise(5);

    reg |= Macro_bitwise(2);
    reg |= Macro_bitwise(7);
    
    reg &= clear_3;
    reg ^= toggle_5;

    return reg;
}

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