Class, Structure and Overload operator equal

[jcc]

Hi,

Im learning the c++ object and structure and operator

A few question:
1. how do you copy the structure address to the operator overload (equal)

struct MyStruct
{
char Name[50];
struct MyStruct *next;
}


class MyClass
{
MyClass();
void Add(MyStruct*);
MyClass operator=(MyClass &);
MyStruct * Head;
}



MyClass::MyClass

:Head(NULL)
{
}

void Add(MyStruct* Add)
{
MyStruct* Entry = new MyStruct;

Entry = Add;
Entry->next = Head;
Head = Entry;
}

MyClass MyClass::operator=(const MyClass &copy)
{

// how can we copy the pointer and return it
}



// main

MyClass* A = new MyClass();
MyClass B; // copied here
MyStruct* Data;
Data = new MyStruct;
strcpy(Data->Name,'first name');

A->Add(Data);

Data = new MyStruct;
strcpy(Data->Name,'Second name');

A->Add(Data);



B=A;




I hope the above example code can help to explain what im trying to achieve

You should call that one "assignment" operator. "Equals" would be == in C++. You can't use operators directly with pointers, so you'd either have to do this:
*B=*A
or this
B->operator=(*A);

Btw, try to use pointers only when it's necessary - if you are just passing something around, just use references.
