    What I've learned: 1. In try-catch structure, throw passes a value to the catch section.

    1. Class(arg) also can create object of the class "Class" called "arg"?? I thought I could use a parameterized constructor to get the letter length and override what() method to print it out. I'm still wandering how's it possible for my exception class to accept the letter number "n".

    2. "exception" header imports "exception" base class. We can define our own exception class ourselves.

    class BadLengthException : public exception
{
    private:
		int n;
    // override what() to return the letter length
    public:
    BadLengthException(int length)
    {
        n = length;
    }
    
    int what()
    {
        return n;
    }
};

    class BadLengthException : public exception{
    private :
        std::string size;
        
    public:
    BadLengthException() noexcept= default;
    ~BadLengthException() = default;
    BadLengthException(int n) : size{std::to_string(n)} {}
    virtual const char * what() const noexcept override{
        return size.c_str();
    }
        
};
