一个分别在栈和自由存储区创建和删除对象的例子

//Create objects on the free store//using new and delete#include <iostream>using namespace std;class SimpleCat{public: SimpleCat(); ~SimpleCat();private: int itsAge;};SimpleCat::SimpleCat(){ cout << "Constructor called." << endl;}SimpleCat::~SimpleCat(){ cout << "Destructor called." << endl;}int main(){ cout << "SimpleCat frisky..." << endl; SimpleCat Frisky; cout << "SimpleCat *pRags = new SimpleCat" << endl; SimpleCat *pRags = new SimpleCat; cout << "delete pRags..." << endl; delete pRags; cout << "Exiting, watch Frisky go..." << endl; //system("pause"); return 0;}/* 用MinGW Develop Studio编译器的运行结果：SimpleCat frisky...Constructor called.SimpleCat *pRags = new SimpleCatConstructor called.delete pRags...Destructor called.Exiting, watch Frisky go...Destructor called. */

由于用Dev编译器查看结果必须在return语句前面加一句

system("pause");

而此时程序还没有结束，因此对象Frisky还没有被解析，所以上一个显示结果的最后一句

Destructor called.

将不会显示。
