C++ 异常处理 terminate函数使用

code：

#include <iostream>
using namespace std;

void terminator(){
	cout << "I 'll be back!" <<endl;
	exit(0);
}

void (*old_terminate)() = set_terminate(terminator);


class B{
public :
	class A{};
	void f(){
		cout<<"B::f()"<<endl;
		throw A();
	}
	~B(){
		throw 'c';
	}
};

int main(){
	try{
		B b;
		b.f();
	}catch(...){
		cout<<"inside catch(...)"<<endl;
	}
	return 0;
}
