Access Specifiers.First of all, classes are reference types and structs are value types. It will also be our style to use access keywords explicitly and to place public members first and private members last. Le tableau suivant .In a class definition, the default access for members and base classes is private.
Difference between class (Python) and struct (C)
Structure : - Passé par défaut en valeur, pas par référence (modifier une structure dans une méthode n'affecte pas la structure originale que l'on a envoyé à ladite méthode) Classe : - Passée par défaut par référence (inverse de valeur) En gros c'est ça la différence, le reste ce sont des détails. int n; }; creates a new type called struct foo.The struct keyword is used to define, or to refer to, a structure type.En C, vous devez utiliser explicitement l’mot clé struct pour déclarer une structure.Balises :C++Struct and ClassStruct vs Class Structs are stored on the stack whereas Classes .

The only difference is the default public/private access of their members. A union is essentially a way to access same data in different ways (For example, you can access/interpret 4 bytes of memory as 1 integers, or as 4 characters).
La classe est un plan ou un ensemble d’instructions pour construire un type . Another major difference between them is that during inheritance , the class keyword inherits the members in private mode, while the struct keyword inherits the members in public mode by default.; The members are automatically initialized by the structure, whereas constructors and destructors are used for initializing members of a class. This means that structs are copied by value when they are passed around, while classes are copied by reference.

Difference between Structs and Classes: Struct are value types whereas Classes are reference types.The main difference between structures and classes is that by default, all member of the structure are public. The name foo is a tag; it's meaningful only when it's immediately preceded by the struct keyword, because tags and other identifiers are in distinct name spaces.

It can be declared using the class keyword.; The memory allocates on the stack when the structure is .The only two technical difference are that the default access specifier is public: for a struct, whereas it is private: for a class and that the compiler will generate a constructor from brace enclosed initializers for structs but not for classes (given that no ctor is declared). Structure can be declared using the struct keyword. Other thing, is using some features -- like, constructors, destructors and virtual functions, -- could have some performance penalties (but if you use them you .So it doesn't make any performance difference whether you use struct A or class A in your code. – Nicol Bolas.
