RE: Inheritance

Structures can be inherited. They are almost similar to classes in C++. The only difference is that the default access specifier in struct is public while it is private in a class.
Now I wanted to mention what I observed. You can inherit a class in a structure but you cannot inherit a structure inside a class. You may want to try this out. Because I tried it out.
class A
{
public:
A()
{
cout<<"IN A";
}
int a;
};
struct B : public A //This will work
{
};
struct C
{
//int c;
}
class D: public C //This won't work
{
};
int main()
{
D d;
A abc;
B bad;
B.a = 1;
D.c = 2; //This would not work
system("PAUSE");
return 0;
}
