STL：栈解旋

栈解旋概念&＃xff1a;当throw抛出异常后&＃xff0c;创建的class类对象就会被析构。

案例&＃xff1a;

class Person {
public:Person() {cout << "对象构建&＃xff01;" << endl;}~Person() {cout << "对象析构!" << endl;}
};
//栈解旋概念&＃xff1a;当throw y抛出异常后&＃xff0c;p1、p2就行进行析构函数。
int divide(int x, int y) {Person p1, p2;if (y &＃61;&＃61; 0) {throw y;}return x / y;
}
void test01() {try {divide(10, 0);}catch (int e) {cout << "异常捕获&＃xff01;" << endl;}
}
int main() {test01();
}


结果&＃xff1a;
