Clear the Bit in an 8-bit Register

Code

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

uint8_t clear_bit(uint8_t reg, int pos){
    reg &= ~(1 << pos);
    return reg;
}

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