tccicomputercoaching.com • Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types.

• The simple idea is to pass data type as a parameter so that we don’t need to write same code for different data types.

• Template allows a function or class to work on many different data types without being rewritten for each one.

tccicomputercoaching.com • For example if we want to sum of two different types of numbers then we have to do individual user defined function for each type of data. • This increases time and memory space. But using template function we have to write once generic function, so, it will decrease the length and complexity of programme.
