Web Reference: May 21, 2025 · A class declaration can appear inside the body of a function, in which case it defines a local class. The name of such a class only exists within the function scope, and is not accessible outside. A C++ program consists of various entities such as variables, functions, types, and namespaces. Each of these entities must be declared before they can be used. A declaration specifies a unique name for the entity, along with information about its type and other characteristics. In C++ the point at which a name is declared is the point at which it becomes visible to the compiler. You can't refer to a function or class that is declared at some later point in the compilation unit. Variables should be declared as close as possible before the point at which they're used. Oct 21, 2025 · Classes are generally declared in global scope and are accessible to every function or other classes once they are defined. But C++ also provides facility to define a class within a function.
