Introduction to Templates In C++

Templates:


Templates in C++ allow you to create objects of any type. In other programming languages like C# this is also referred to as generics. In the datastructures and algorithms class we are expected to understand what templates are and how to use them.

 
template   <class G>
G sampleFunction(G a){
return a;
}

Note: Templates are compiled when they are required so that means you have to put the class definition and implementation in the same file.
