Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    if((reg&(1<<5))!=0){
        reg &=~(1<<3);
         reg &=~(1<<5);
         reg|=(1<<2);
         reg|=(1<<7);
    }
    else {
        reg &=~(1<<3);
         reg |=(1<<5);
         reg|=(1<<2);
         reg|=(1<<7);
    }
    return reg;
}

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