Difference Between Class and Structure in C++

Difference Between Class and Structure in C++

In the era of programming, We are aware of how C++ programming has evolved over time. Through this article, we are looking at the various difference between class and structure in C++. A structure will perform the same way as a class regardless of those two differences. Their major function is hiding implementation details. Hence, in short, the structure will provide its implementation details for its users. Whereas, a class won’t show its implementation details and thus will indeed restrict the programmer from accessing it. The table below represents the difference between class and structure.

Class And Structure

Class Structure
Members of the class are not revealed to everyone.Members of the class are revealed to everyone.
A “class” is a blueprint, and an “object” is what you create based on that blueprint.
In structure, use that blueprint to create an actual structure in memory, we call it an “object” or “structure instance.
All programming languages have default behavior even though their members are private.In OOP languages, use class keywords to create a blueprint for objects with attributes and behaviors.


Whereas, class is responsible for grouping data.



A structure is declared using the struct keyword. It’s like a lightweight version of a class for organizing data.
It functions for data abstraction and further inheritance.

Whereas, class is responsible for grouping of data.



Null values are present in class.Null values are absent in structure.

Syntax for class

class class_name{

         data_member;

         member_function;

Syntax for structure

struct structure_name{

         type structure_member1;

         type structure_member2;

   };

FAQ- Difference Between Class and Structure

Q 1. What is a structure in C++ for example?

Ans.Structures (structs) group related variables (members) of different data types together. Example: An employee’s will include details of salary, position, experience, etc. Hence, it will be stored in one single variable using structures.

Q 2. How many types of structures are there in C++?

Ans. In C++, structures can have two types of members: data members (variables of different types) and member functions (normal C++ functions).

Q3.What is an array of structures in C++?

Ans. An array is a collection of data items of the same type, like int, char, float, etc. In contrast, a structure allows elements of different data types to be grouped together under a single name.
