5. Clear the Bit in an 8-bit Register

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

uint8_t clear_bit(uint8_t reg, uint8_t pos) {
    // Your code here
    reg &= ~(1 << pos);
    return reg;
}

int main() {
    uint8_t reg, pos;
    scanf("%hhu %hhu", &reg, &pos);
    uint8_t result = clear_bit(reg, pos);
    printf("%u", result);
    return 0;
}

#include <stdio.h>

#include <stdint.h>

uint8_t clear_bit(uint8_t reg, uint8_t pos) {

    // Your code here

    reg &= ~(1 << pos);

    return reg;

}

int main() {

    uint8_t reg, pos;

    scanf("%hhu %hhu", &reg, &pos);

    uint8_t result = clear_bit(reg, pos);

    printf("%u", result);

    return 0;

}

The scanf line on the main function seems to be incorrect. It should take &reg, but I get ® instead.
