达内IT培训Unix C++第二天源码 是入门Unix 下C++编程的好东西

#include <iostream>
using namespace std;
#include <stdlib.h>
#include <unistd.h>

void f(){cout<<"call f()"<<endl;}
void func(){
	cout << "into func()" << endl;
	_exit(0);
	cout << "out func()" << endl;
}
class A{
public:
	A(){cout<<"A()"<<endl;}
	~A(){cout<<"~A()"<<endl;}
};
int main()
{
	A obj;
	atexit(f);
	cout << "hello" << endl;
	func();
	cout << "world" << endl;
