Ex 2: Validating Password

Jin builds his website and wants to develop the back-end of the sign-up page for jAccount. In one of his programs, he has to write a function that checks if the password user submitted to the webserver is valid:

• Contains at least 1 alphabetic characters;
• Contains at least 1 numerical characters;
• Contains at least 1 non-alphanumeric characters.

The function takes a password (an array of chars) as input, returns true if the password is valid and returns false if not.

bool isValidPassword(char password[]){
    // TODO: Implement this function.
}

You are told that no password contains more than 50 characters. Please help him implement the function.
