Fundamentals of C + + entry (1) How to write a simple class and instantiate it

The Basic of C + + Class

A simple class, that stored a data.

Key Points

1.include<iostream>
2.using namespace Std;
3.the function of the class is as followed:
1) Store a data

3) constructor using 0 as default data
4) or give a initial data in parameter
4.main:
1) int Main
2) return 0
3) Instance Object statement
4) Endl
5) System ("Pause")
