ptracc.cpp

本课程主要介绍面向对象程序设计的方法和c++语言的基本概念。以c++语言中的面向对象机制为主。学习者在学习过程中可以通过大量的程序实例和相关练习

// ptracc.cpp
// accessing the variable pointed to
#include <iostream>
using namespace std;

int main()
   {
   int var1 = 11;             //two integer variables
   int var2 = 22;

   int* ptr;                  //pointer to integers

   ptr = &var1;               //pointer points to var1
   cout << *ptr << endl;      //print contents of pointer (11)

   ptr = &var2;               //pointer points to var2
   cout << *ptr << endl;      //print contents of pointer (22)
   return 0;
   }
