Bit Operations using Macros

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg =reg |(1<< 2);
    reg =a |(1<< 7);
    reg =b & ~(1<<3);
    reg =c ^ (1<<5);
    return reg;
}

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