⟩ Define the syntax and semantics for a function template?

Templates is one of the features of C++. Using templates, C++ provides a support for generic programming.

We can define a template for a function that can help us create multiple versions for different data types.

A function template is similar to a class template and it syntax is as follows:

template <class T>

Return-type functionName (arguments of type T)

{

//Body of function with type T wherever appropriate

}
