What are the advantages of C++ templates?

There are several advantages to C++ templates:

1. Code reusability refers to the ability of templates to generate the same code on different data types, allowing for code reuse. This helps reduce repetitive coding, improving code maintainability and readability.
2. Compile-time type checking: By using templates, generic code can be checked for types at compile time, allowing potential type errors to be identified in advance. This helps reduce runtime errors, and enhances the robustness and reliability of the code.
3. High performance: Templates can improve program execution efficiency by generating code for specific data types at compile time. The generated code can operate directly on specific data types without the need for type conversion and dynamic dispatch, thereby enhancing program performance.
4. Flexibility: Templates can adapt to different data types and structures, allowing them to be used flexibly in various scenarios. By parameterizing templates, specific code can be generated to meet different application needs in various scenarios.
5. Scalability: Templates provide a mechanism to extend the capabilities of the C++ language by adding specific functionalities in templates. This makes C++ more flexible and powerful, allowing it to meet more complex application requirements.
