/*
    Read a list of strings and we will store them in 2D character array
    
    - cin                                  : It doesn't read spaces & newline
    - cin.get()                            : Read single character (including spaces & newline)
    - cin.getline(char* ch, int size)      : Read a line from an input stream (Syntax for Character Array)
    - getline(istream& cin, string& str)   : Read a line from an input stream (Syntax for String)
        
        Where,
        char*    : It is a character pointer that points to the array.
        size     : It acts as a delimiter that defines the size of the array means input cannot cross this size.
        string&  : It is a string object, the input is stored in this object after being read from the stream.
        istream& : It is an object of istream class and tells the function about the stream from where to read the input from

    Syntax:
    1. istream& getline (istream& is, string& str, char delim);
