Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_BIT_2       2
#define SET_BIT_7       7
#define CLEAR_BIT_3     3
#define TOGGLE_BIT_5    5


uint8_t modify_register(uint8_t reg) {
    reg |= ((1 << SET_BIT_2) | (1 << SET_BIT_7));
    reg &= ~(1 << CLEAR_BIT_3);
    reg ^= (1 << TOGGLE_BIT_5);
    return reg;
}

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