Creating beginner program

[nergal]

Hello all, I'm a new user and for 3 years, I've been doing some coding using a scripting language called Pawn for a game called Team Fortress 2.

From those 3 years, I've been using Pawn to create plugins for servers such as my own but I've just about had it with Pawn and I want to branch out to a REAL programming language.

My few choices were C, C++, Java, Python, and Lua.

I ultimately decided that I want my first language to be C++ :D

the tutorial section taught me pretty much what I already learned from using Pawn scripting but when I got to pointers, I got completely stumped :)

I figured that, in order to help me and others learn (I learn by example), I made an educational program for programming students to quickly learn about C++. The program is modeled after a Vending Machine!

#include <iostream>
using namespace std;

struct venditem_t //struct names usually have "_t" as their suffix in terms of conventional C++ programming.
{
	int m_iCode;
	string szItemName;
	float m_flPrice;
};
/*it should be noted that structs can work basically the same way as classes do but structs have their data public by default*/

class CVendingMachine /*name is preceded with C to note that it's a class, classes have their data private by default*/
{
	/*most member variables have "m_" or just "m" prefixed to their name to denote it's a member of a class.*/
	int m_iVendSpace[20]; //space of rows for items to be vended from.
	venditem_t m_iItem[20]; //make an instance of a struct in a class.
	bool m_bHasDrinks; //does machine vend drinks too?
};

int main()
{
	//do shit here
	return 0;
}

To get a basic gist of what I'm trying to do, I'm basically remaking the tutorials section but into a single, giant program for beginners and differently-experienced programmers to dissect and see. It'll essentially be a reference guide on what C++ can do.

Considering that many of you posting are 10x alot better than me at the moment, How can I implement all of the capabilities that C++ has into this one program so that I and others can learn?
