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) {
    // Your logic here
    int val = 0, i = 0;
    while(str[i] == '1' || str[i] =='0'){
        val =  (val<<1)| (str[i] - '0');
        i++;
    }
    return val;
}

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

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