Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    int pos;
    for(pos=7;pos>=0;pos--)
    {
        if(pos==2|| pos==7)
        reg=reg|(1<<pos);
        else if(pos==5)
        reg=reg^(1<<pos);
        else if(pos==3)
        reg=reg&~(1<<pos);
    }
    return reg;
}

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