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
    // to set bit 2 and 7;
    int mask = 1<<2;
    reg = reg | mask;
    mask = 1<<7;
    reg = reg | mask;
    //clear bit3;
    mask = 1<<3;
    reg = reg & (~mask);

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

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