Bit Operations using Macros

Code

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

#define set2bit 1<<2
#define set7bit 1<<7
#define clear3bit 1<<3
#define toggle5bit 1<<5
// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    reg |= (set2bit | set7bit);
    reg &= ~(clear3bit);
    reg ^= toggle5bit;
    return reg;
}

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