Modifying a Scrabble algorithm to build a password tool,

Question

I'm trying to update it from using the string library to using char*, but it keeps giving me an error while trying to use get_char while compiling.

#include <stdio.h> #include <stdlib.h> #include <ctype.h>

#define MAX 13; #define MIN 8;

//points assigne for lettering int POINTS[] = {1, 3, 3, 2, 1, 4, 2, 4, 1, 8, 5, 1, 3, 1, 1, 3, 10, 1, 1, 1, 1, 4, 4, 8, 4, 10};

int main(void) { //Asking client for password entry char* password = get_char("What is your Password?: ");

if(strlen(password) > MAX)
{
    printf("Usage, Password is too long. Must be no more than 13 Characters\n");
    return 1;
}

if(strlen(password) < MIN)
{
    printf("Usage, Password is too short. Must be at least 8 Characters\n");
    return 1;
}

int score =0;

for(int i = 0; i < strlen(password); i++)
{
    if(isupper(password[i]))
    {
        score += POINTS[password[i]-65];
    }
    else if(islower(password[i]))
    {
        score += POINTS[password[i]-97];
    }
    return score;
}
printf("Password score: %i\n", password);

}

get_char is a function in the CS50 library; to use it, cs50.h needs to be included. Here is one place to start if you don't want to use the cs50 library at all.
