Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    uint8_t maskSet = (1 << 7) | (1 << 2);
    uint8_t maskClear = (1 << 3);
    uint8_t maskToggle = (1 << 5);
    reg |= maskSet;
    reg &= ~(maskClear);
    reg ^= maskToggle;
    return reg;
}

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