Convert Binary String to Integer Without strtol function or Libraries

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



uint16_t binary_to_uint(const char *str) {
    // Your logic here
    int count = 0;
    uint16_t result = 0;
    for (int i = 0; str[i] != '\0'; i++){
        result = result * 2 + (str[i] - '0');
}
    return result;
}
int main() {
    char bin[20];
    scanf("%s", bin);

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