Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_SECOND_BIT(x)   x |= (1<<2)
#define SET_SEVENTH_BIT(x)   x |= (1<<7)
#define CLEAR_THIRD_BIT(x)   x &= ~(1<<3)
#define TOGG_FIVTH_BIT(x)   x ^= (1<<5)



uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    SET_SECOND_BIT(reg);
    SET_SEVENTH_BIT(reg);
    CLEAR_THIRD_BIT(reg);
    TOGG_FIVTH_BIT(reg);
    return reg;
}

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