Summary

A short summary.

So far, I have introduced templates programming step by step with some examples. I didn't explain many things by myself, I tried to show you how it works.

Bearing all of this in mind, it's time to go over the profits of templates and the reason of being so interesant.

• Templates are type-safe: The compiler is able to do the type checking before a error occurs.

If you write general code for a common base class you lose this benefits. Moreover  is expected you may derive this class, which makes it even more difficult to maintain.

• Easiness writing them: With just one class we may have an infinity number of uses

Remember the example of max, with which one we saved many definitions. 

• Optimize the runtime by compiling time: This point, I'd like to flesh out through metaprogramming but stay with the idea.

• Good possibility to reuse code.
