Introduction to C + + Classic-Example 5.15-general processing steps for recovering dynamic memory

1: The correct step should be as shown in the following code:

//5.15.cpp: Defines the entry point of the console application. //#include"stdafx.h"#include<iostream>voidSwapintAint*b) {    inttemp = *A; *a = *b; *b =temp;}intMain () {int* PI =New int; *pi =3; intK =5; Swap (PI,&k); Std::cout<<"*pi:"<<*pI<<std::endl;//using the Std namespacestd::cout<<"K:"<<k<<Std::endl; DeletePI;//Reclaim Dynamic MemoryPI = NULL;//empty the Pi to prevent the use of destroyed memory. And the previous statement cannot be reversed, otherwise it will cause a memory leak    return 0;}//after delete, do not forget to empty the pi to prevent the use of memory that has already been destroyed.
