This article introduces the knowledge of "how to use templates in C++". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

T.2: using templates to represent algorithms that can be applied to multiple parameter types

Reason (reason)

Generality. Minimizing the amount of source code. Interoperability. Reuse.

Generality. Minimize the amount of code. Interoperability. Reuse.

Example (sample)

That's the foundation of the STL. A single find algorithm easily works with any kind of input range:

This is the foundation of STL (Standard template Library). A simple retrieval algorithm can be easily applied to any type of input range:

Template

/ / requires Input_iterator

/ / & Equality_comparable

Iter find (Iter b, Iter e, Val v)

{

/ /...

} Note (note)

Don't use a template unless you have a realistic need for more than one template argument type. Don't overabstract.

If you do not have actual requirements that require multiple parameter types, do not use templates. Don't be too abstract.

Enforcement (implementation recommendations)

It's hard. You may need to think that judgment.
