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

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