The link between classes and objects and function templates and function-template specializations is the most comparable.
It is possible to define default type arguments for type parameters in both class templates and function templates. Function-template specializations and overloaded functions vary in that they: Specializations of function-templates are produced by the compiler, not the programmer.
C++'s templates are strong capabilities that let us create general-purpose applications. Using a template, we can build a single function that handles several data types.
