Note I will not grade you on correctness in your answers; I'm just looking to see that you attemped the problems and that you show your work.

Question 1 - Hex to Decimal

Question 4 - Bad string_to_int()

Consider the following incorrect implementation of string_to_int():

int string_to_int(char *s) {
    int result = 0;
    for (int i = 0; s[i] != '\0'; i++) {
        result = result * 10 + s[i];
    }
    return result;
}

This function is supposed to convert a string of digits into an integer. However, it does not work as expected. Identify and explain the problem with this code. Show the corrected version.
