Question

difference between classes and structure in c++.​

Answer 1

To understand the main difference between structure and class :-

The C++ class is an extension of the C language structure. Because the only difference between a structure and a class is that structure members have public access by default and class members have private access by default, you can use the keywords class or struct to define equivalent classes.

For example, in the following code fragment, the class X is equivalent to the structure Y:

class X {

// private by default

int a;

public:

// public member function

int f() { return a = 5; };

};

struct Y {

// public by default

int f() { return a = 5; };

private:

// private data member

int a;

};
