In this blog post, you will learn about templates in C++ with the help of programming examples. Templates are powerful features of C++ that allow us to write generic programs. It allows us to define a family of classes, functions, or variables, an alias for a family of types, or a concept. That means as a
An enumeration is a distinct type (user-defined type) with named constants that are known as enumerators. The name of the enumeration becomes an enum name within its scope. In C++, the enumeration type is declared with an enum key. These enum keys can be only an enum or enum class or enum struct. The enum
