Bit Operations using Macros

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

// Define bitwise macros here
#define set(r, b)    r |= 1 <<b
#define clear(r,b)   r &= ~(1<<b)
#define tog(r,b)     r ^= 1<<b
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    set(reg,2);
    set(reg,7);
    clear (reg,3);
    tog (reg,5);
    return reg;
}

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