Classes ii overloading operators classes essentially define new types to be used in c code.
In simple terms you can create a single function or a class to work with different data types using templates. It was designed with a bias toward system programming and embedded resource constrained and large systems with performance efficiency and flexibility of.

A tutorial and handbook. While the title of this article is a question it could also be made into a statement. Templates are a feature of the c programming language that allows functions and classes to operate with generic typesthis allows a function or class to work on many different data types without being rewritten for each one.
Templates are powerful features of c which allows you to write generic programs. Templates are of great utility to programmers in c especially when combined with multiple inheritance and operator overloading. A template is a blueprint or formula for creating a generic class or a function.
But they are the most convenient portable solution. Templates are among the most powerful features of c but they are too often neglected misunderstood and misused.
