118. Convert Binary String to Integer Without strtol function or Libraries

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

uint16_t binary_to_uint(const char *str) {
    uint16_t val = 0;
    while (*str == '1' || * str == '0'){
        val = (val << 1) | ( *str - '0');
        *(str++);
    }
    // Your logic here
    return val;
}

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

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