C++中设置Main函数结束后执行的代码_艾孜尔江撰

#include <iostream>
#include <cstdlib>
using namespace std;


int func1(),func2(),func3();

int main(int argc,char * argv[])
{
	_onexit(func2); //函数注册时入栈，调用时出栈 
	_onexit(func1);                   
	_onexit(func3);
	cout<<"First Line"<<endl;
	cout<<"Second Line"<<endl;
}

int func1()
{
	cout<<"fun1() is executed!"<<endl;
	return 0;
}

int func2()
{
	cout<<"fun2() is executed!"<<endl;
	return 0;
}
int func3()
{
	cout<<"fun3() is executed!"<<endl;
	return 0;
}

效果
