C++ 派生类的析构函数的执行顺序
C++中派生类是不会继承父类的构造函数和析构函数的,这一点要明确。派生类中构造函数的执行顺序是先父类的构造函数然后当前类,析构函数则相反。举例如下:
#include <iostream>
using namespace std;
class A
{
public:
A() { cout << "A constructor" << endl; };
~A() { cout << "A destructor" << endl; };
};
class B : public A
{
public:
B() { cout << "B constructor" << endl; };
~B() { cout << "B destructor" << endl; };
};
class C : public B
{
public:
C() { cout << "C constructor" << endl; };
~C() { cout << "C destructor" << endl; };
};
int main()
{
C c;
return 0;
}上述代码执行后效果如下:
