2d string and int array

[keewong]

Hi, I just started an assignment, and of course, new to c++, please forgive my ignorance.

I'm trying to create a 2d array, one column stores, a word(string) and the other column stores the word count(int)..

I'm supposed to use classes, and perhaps structs.. i just don't know how to do this..

How can I declare this? I am at a loss, here.

thanks in advance.

You can't create two mixed datatypes in an array so you couldn't have the first be a string and second dimension be an int so yes you would want to use a class or struct. I would probably use struct since it defaults to public. Be sure to have the string header included when you do this with #include <string>. I would do something probably like the following below though:

struct characteristics {
string word;
int counter;
};

Then you can create datatypes of that struct so it'd look like characteristics my_variable; for example. Let me know if this helped.

thanks for your quick reply, Mike,

can I put the struct, you created into a Class Word?

class Word
{
	public:
		void setup();
		void get();
		void set();
    private:
		struct characteristics
		{
			string word;
			int counter;
		};
};

If so.. how can I create new objects in the struct?
Word.characteristics word1; // is this how I create a new word item?

And also, how can I access word1?
cout << word1.word; // i.e. is this how I can access the word?

Overall, sorry - I keep reading the books and notes, but I can't seem to identify what I need to do.. :(

If you are declaring it inside Word, you can use characteristics word1,
Outside Word, Word::characteristics word1

I'm a little out of practice personally with advanced concepts in object-oriented programming, especially when you have classes or structs nested within each other but I do know that a good resource that explains the details of that is Bruce Eckel's first volume of Thinking in C++ Second Edition which is free. Just Google it and you should find it for downloading or viewing online.

Hay Bazzy, that makes perfect sense.. thanks!
and thanks Mike for the reference, I'll check it out.
I think that would work, but I think - I can just do it inside the class without the struct..

class Word
    {
        public:
            void setup(string);
            int getCount();
            string getWord(); 
            void setWord(string);
	    void setCount(int);
	private:
            string word;
	    int wordCount;
       
} word[500];
