Convert Binary String to Integer Without strtol function or Libraries

Code

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

uint16_t binary_to_uint(const char *str) {
    // Your logic here
    uint16_t result = 0;
    while (*str == '0' || *str == '1') {
        result <<= 1;                 // shift left
        if (*str == '1')
            result |= 1;              // set bit if '1'
        str++;
    }

    return result;
    return result;
}

int main() {
    char bin[20];
    scanf("%s", bin);

    printf("%u", binary_to_uint(bin));
    return 0;
}
