程序代码：

#include"stdafx.h"
#include<iostream>

using namespace std;

int* newPointerGet(int* p1)
{
    int k1 = 55;
    p1 = new int;
    *p1 = k1;
    return p1;
}

int* PointerGet(int* p2)
{
    int k2 = 55;
    p2 = &k2;
    return p2;
}

int main()
{
    cout << "输出函数各自返回指针所指向的内存的值" << endl;
    int* p = NULL;
    p = newPointerGet(p);
    int* i = NULL;
    i = PointerGet(i);
    cout << "newGet:" << *p<<endl ;
    cout << "Get:" << *i << endl;//*i 的值不是55，显示为：260090768，每次编译显示的值还不一样。
    cout << "i 所指向的内存没有被立刻销毁，执行一个输出语句后：" << endl;
    cout << "newGet:" << *p << endl;
    cout << "get:" << *i << endl;
    delete p;
    cout << "销毁内存后：" << endl;
    cout << "newGet:" << *p << endl;
    return 0;
}
