Bit Operations using Macros

Code

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

// Define bitwise macros here
#define bit2  (1<<2)
#define bit7  (1<<7)
#define bit3  ~(1<<3)
#define bit5  (1<<5)


uint8_t modify_register(uint8_t reg) {
    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;
}
