Structure: Initially (in C) a structure was used to bundle different type of data types together to perform a particular functionality. But C++ extended the structure to contain functions also. The major difference is that all declarations inside a structure are by default public. Class: Class is a successor of Structure. By default all the members inside the class are private.

Structure does support inheritance.

try out the following code.

#include<iostream>

using namespace std;

struct Base
{
    int A;
};

struct Derived:public Base
{
    int B;
    void display();
};

void Derived::display()
{
    cout<<endl<<"A = "<<A<<endl;
}

int main()
{
    Derived D;
    D.A = 111;
    D.display();
    getchar();
    return 0;
}

Try out private and protected inheritance as well. It works. :)

All data members of the class is by default private,
Whereas all data members of structure is by default public.

Beware, whatever is supported by a class is also supported by struct whether its inheritance, polymorphism, encapsulation, data hiding etc. etc. as of C++ 11. Only difference is, for a class default access specifier is private whereas for struct its public.
