C++ template handle class with no member
WebOct 16, 2024 · Templates are the basis for generic programming in C++. As a strongly-typed language, C++ requires all variables to have a specific type, either explicitly declared by the programmer or deduced by the compiler. However, many data structures and algorithms look the same no matter what type they are operating on. WebFunction templates are special functions that can operate with generic types. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type. In C++ this can be achieved using template parameters.
