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
    // set bit 2 and 7
    reg = (reg & ~((1<<7)|(1<<2))) | ((1<<7)|(1<<2));

    // clear bit 3
    reg &= ~(1<<3);

    // toggle bit 5
    reg ^= (1<<5);
    return reg;
}

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