        a = 100;
    }
 
    int getA()
    {
        return a;
    }
 
    void setA(int temp)
    {
        a = temp;
    }
 
    ~Test()
    {
        cout<<"Destructor function called."<<endl;
    }
};
 
int main(int argc, char* argv[])
{
    Test testStruct;
    testStruct.setA(10);
    cout<<"Get the value from struct:"<<testStruct.getA()<<endl;     
        Test *testStructPointer = new Test;     
        testStructPointer->setA(20);
    cout<<"Get the value from struct again:"<<testStruct.getA()<<endl;
    delete testStructPointer;
 
    // test the constructor
    Test testConstructor;
    cout<<"Set the value by the construct and get it:"<<testConstructor.getA()<<endl;
 
    return 0;
}

 

是的,完全支持析构函数。

Struct支持继承么?

再让我写代码验证一下:

#include <iostream>
using namespace std;
 
struct A
{
    int a;
    A()
    {
        a = 10;
    }
    void print()
    {
        cout<<"I am from A"<<endl;
    }
};
 
struct B : A
{
    int b;
    B()
    {
        a = 30; // set a to 30
        b = 20;
