Structure Vs Class in C++

The structure in C++ is similar to that of a class, with a few exceptions. Both the structure and the stage, the most important thing is safety. The property is not secure as it was not able to hide its usage details from the end user, while the category is as secure as it could hide its planning and design details. The differences between structure and class in C ++ will be discussed in this article.

C++ Structure

A structure is a collection of variables of different data kinds with the same name. A structure declaration acts as a template for constructing a structure instance. The structure's syntax is as follows:

Struct name  //syntax
.  .  .  

The keyword "struct" tells the compiler that a structure has been defined. The "name" specifies the structure's name. The structure declaration is commonly followed by a semicolon because it is viewed as a statement.

C++ Class

In C ++, the category is similar to structure C because it has a list of data members and a set of tasks that can be performed on it. To put it another way, the classroom is the basis of programs that focus on things. A class model is a type of user-defined object with its own set of data members and member functions that can be accessed and used. A C++ class is equivalent to the blueprint of an object. Syntactically, the structure and the class are comparable. The following is the C++ class syntax:

class name  //syntax
// private data members and member functions.  
Access specifier;  
Data member;  
Member functions (member list){ . . }  


The class keyword is used in this syntax to tell the compiler that a class has been declared. Data hiding is the core function of OOP, which is accomplished using three access specifiers: "public," "private," and "safe." When declaring data members or member functions in a class, if no access specifier is supplied, they are all deemed private by default. Others can use the public access specifier to access program functionalities or data. Only the class's private members can be contacted by a member of that class. The secure access specifier is utilized during inheritance. The access specifier cannot be modified once it has been defined in the program.


  • All members of the structure are public by default. The class, on the other hand, is entirely private.
  • A particular approach can be used to describe operators that will work on the new data form.
  • Draft members will be started automatically. Builders and destroyers, on the other hand, are used to launch class members.
  • Memory is allocated to the stack when the outline is used. In the classroom, however, memory is given in abundance.
  • In structure, flexibility cannot be implemented at the time of declaration, although it may be possible in the classroom.
  • Any member of the framework cannot have empty values. On the other hand, class variables may have empty values.
  • A category is a type of reference, but a structure is a type of value.

A side-by-side examination of the structure and class in C++

CharacteristicsStructure in C++Class in C++
ExplanationA structure is a collection of variables of different data kinds with the same name.A class in C++ is a single structure that contains a collection of linked variables and functions.
PrimitiveAll members are set to 'public' if no access specifier is supplied.All members are set to 'private' if no access specifier is given.
DeclareStruct name  //syntax {  Struct_name1;  Struct_name2;  Struct_name3;  .  .  .  Struct_nameN;  }; class name{ data member; member function; };
InstanceThe 'structure variable' is the name for a structure instance.The term 'object' refers to a class instance.
InheritanceIt is not compatible with inheritance.It is compatible with inheritance
Allocation of memoryThe stack is used to allocate memory.The heap is used to allocate memory
NatureType valueType reference
OccasionData classificationFurther inheritance and data abstraction
UtilizationIt's for tiny amounts of information.It stores a large amount of data.
Null valueImpossibleNull values are possible.
Builder and destroyer are required.It's possible that it only has a parameterized function Object () { [native code] }.It could contain any number of constructors and destructors.

Common between Structure and class in C++

  • Any of the members of a class or structure can be declared private.
  • Inheritance procedures are supported by both class and structure.
  • In C++, class and structure have the same syntactic meaning.
  • The name of a class or structure can be used as a stand-alone type.
NOTE: The inability to hide data, the inability to treat 'struct' data as built-in types, and the lack of inheritance support are all limitations of Structure in C. These flaws were overcome by the C++ structure. In C++, a class is an enhanced form of the structure. The programmer has made it simple to utilize the class to store both data and functions, whereas the structure simply stores data.
