Bit Operations using Macros

Code

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

// Define bitwise macros here
#define clear (~(1<<3))
#define toggle (1<<5)
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg = reg |1<<2;
    reg = reg |1<<7;

    //reg = reg&~(1<<3);
    reg = reg&clear;

    //reg = reg^1<<5;
    reg = reg^toggle;
    return reg;
}

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