对应c++拷贝方式，我倒是较熟悉。但是对应指针的拷贝，我有些迷糊，所有做了一个简单的程序测试一下。
1 //object.h
2
3 #ifndef OBJECT_H_
4 #define OBJECT_H_
5
6 #include <iostream>
7
8 class object{
9 public:
10 object(){
11 std::cout << "object()" << std::endl;
12 }
13
14 object(const object&){
15 std::cout << "object(const object&)" << std::endl;
16 }
17
18 ~object(){
19 std::cout << "~object()" << std::endl;
20 }
21 };
22
23 #endif /* OBJECT_H_ */
main.cpp
1 #include <iostream>
2 #include "object.h"
3
4 int main(int argc, char **argv) {
5 object obj1;
6 object obj2(obj1);
7 object obj3 = obj2;
8
9 std::cout << "---------------------" << std::endl;
10
11 object *pObj1 = new object();
12 object *pObj2(pObj1);
13
14 std::cout << "pObj1=" << pObj1 << std::endl;
15 std::cout << "pObj2=" << pObj2 << std::endl;
16
17 std::cout << "---------------------" << std::endl;
18
19 return 0;
20 }
输出结果：
经过测试我们可以发现：
object *pObj1 = new object();
object *pObj2(pObj1);
这只是一种简单的值（地址）的拷贝。现在，pObj1和pObj2指向同一个对象。
