Clear the Bit in an 8-bit Register

Code

#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);
    if (pos > sizeof(reg)*8)
    {
        printf("\n USER INPUT ERROR: Given position surpasses the Register Size");
    }
    else{
            uint8_t result = clear_bit(reg, pos);
            printf("%u", result);
        }
    return 0;
}
