Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) 
{
    reg = reg | (1 << 2);

    reg = reg | (1 << 7);

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

    reg = reg ^ (1 << 5);

    return reg;
}

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