C++ Code:

/*
功能：结构体继承自结构体
结论：
1. 结构体可以继承自结构体
2. 结构体同样有构造函数和析构函数
*/
#include <iostream>
using namespace std;
struct MNode
{
int val;
MNode()
{
val = 10;
cout<<"MNode(): "<<val<<endl;
}
~MNode()
{
val = 20;
cout<<"~MNode(): "<<val<<endl;
}
};
struct MList: public MNode
{
char name[10];
MList()
{
strcpy(name, "World");
cout<<"MList(): val="<<val<<", name="<<name<<endl;
}
~MList()
{
strcpy(name, "World2");
cout<<"~MList(): val = "<<val<<", name = "<<name<<endl;
}
void display()
{
cout<<"MList::display(): val="<<val<<", name="<<name<<endl<<endl;
}
};
int main()
{
MList a;
a.display();
strcpy(a.name, "Hello");
a.val = 100;
a.display();
return 0;
}

运行结果：
