The differences between a class and a struct in C++ are: struct members and base classes/structs are public by default. class members and base classes/structs are private by default. Both classes and structs can have a mixture of public, protected and private members, can use inheritance, and can have member functions. I would recommend you:

Jan 11, 2025 · In C++, a structure works the same way as a class, except for just two small differences. The most important of them is hiding implementation details. A structure will by default not hide its implementation details from whoever uses it in code, while a class by default hides all its implementation details and will therefore by default prevent ...

Aug 2, 2021 · This section introduces C++ classes and structs. The two constructs are identical in C++ except that in structs the default accessibility is public, whereas in classes the default is private. Classes and structs are the constructs whereby you define your own types.

Dec 26, 2023 · The choice between using a struct or a class in C++ comes down to the need for encapsulation and functionality. Use structs when you have data that doesn’t require strict control, and use classes when you need to control access to the data and provide functionality.

Apr 12, 2025 · Here is the main difference between Structure and Class in C++: A structure is a user-defined data type that groups related variables. A class is a user-defined data type that acts as a blueprint for objects. Declared using the struct keyword. Declared using the class keyword. Default access specifier is public. Default access specifier is private.

Dec 2, 2024 · In C++, both structures (struct) and classes (class) are user-defined data types, where they both give access to group different data elements (variables) and functions together. However, they still possess a few differences between them. In this article, we will see and go through its differences.

Jun 13, 2017 · Contrary to a struct, a class is made to offer an interface, that has some degree of separation from its implementation. A class is not just there to store data. In fact a user of a class is not supposed to know what data the class is storing, or if …

The difference between struct and class keywords in C++ is that, when there is no specific specifier on particular composite data type then by default struct or union is the public keywords that merely considers data hiding but class is the private keyword that considers the hiding of program codes or data.

Feb 12, 2025 · Understanding the distinction between `class` and `struct` in C++ is crucial for writing clean and maintainable code. While both can be used to define composite data types, their default access levels and intended use cases differ significantly.

In C++, the primary difference between a struct and a class is that members of a struct are public by default, while members of a class are private by default. Here’s an example demonstrating this distinction:
