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
    for(int i=0;i<8;i++){
        if((i==2) || (i==7)){
            reg |= (1<<i);
        }
        if(i==3){
            reg &= ~(1<<i);
        }
        if(i==5){
            reg ^= (1<<i);
        }
    }
    return reg;
}

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