Could you Cite examples to show difference between structures and classes?

Answer 1

The only difference between a struct and a class is that struct members are public by default while class members are private by default. To demonstrate, consider the following code:

#include<iostream>

struct struct_object

{

int m_data;

};

class class_object

{

int m_data;

};

int main()

{

struct_object s;

class_object c;

s.m_data = 42; // ok -- s.m_data has public access by default.

c.m_data = 42; // access denied -- c.m_data is private by default.

}
