Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>
// Define bitwise macros here
#define Set2 (1U<<2)
#define set7 (1U<<7)
#define clear (1U<<3)
#define Xor (1U<<5)

uint8_t modify_register(uint8_t reg) {
    reg|= Set2;
    reg|= set7;
    reg&= ~(clear);
    reg^= Xor;
    return reg;
}
int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", modify_register(reg));
    return 0;
}
