Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    reg |=  (1U << 2);   // set bit 2
    reg |=  (1U << 7);   // set bit 7
    reg &= ~(1U << 3);   // clear bit 3
    reg ^=  (1U << 5);   // toggle bit 5
    return reg;
}

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