C++源码：C++语言中的内存动态分配

// C++ :   Example for (new and delete)
// C++中的动态内存分配

#include <iostream>
#include <malloc.h>

using namespace std;

void fun1();

main()
{
fun1();
}

void fun1()
 {
  int *i=new(int);   //申请内存 用 new
  const int w11=123;
  *i=10;
  cout<<"\n\n        You are Wellcome !   C++中的动态内存分配  \n\n\n";
  cout<<"C+++:   i="<<i<<"\n";
  cout<<"C+++:  *i="<<*i<<"\n";
  cout<<"C+++:  CONST W11= "<<w11<<"\n";
  cout<<"C+++:  Size of INT:  "<<sizeof(int);
  cout<<"\nC+++:  Size of Char: "<<sizeof(char);
  cout<<"\nC+++:  Size of long :"<<sizeof(long);
  cout<<"\n\n         End.    \n\n";
  free(i);     //注意：对于C++对象，释放其所占内存 用 delete ！
