Bit Operations using Macros

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

// Define bitwise macros here

#define SET_BIT(r,b) ((r) |= (1 << b))
#define CLEAR_BIT(r,b) ((r) &= ~(1 << b))
#define TOGGLE_BIT(r,b) ((r) ^= (1 << b))


uint8_t modify_register(uint8_t reg) {
    // Apply operations in order

    //Set bit 2 and 7
    SET_BIT(reg,2);
    SET_BIT(reg,7);

    // Clear bit 3
    CLEAR_BIT(reg,3);

    // Toggle bit 5
    TOGGLE_BIT(reg,5);

    return reg;

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
