What is C++ library versioning and why is it important?

C++ library versioning refers to the practice of assigning version numbers to libraries to manage changes and compatibility. It's important because it helps developers understand which versions of a library are compatible with their code, ensuring stability and reducing bugs.

How do I implement versioning in my C++ library?

To implement versioning, you can use semantic versioning (SemVer), which consists of three numbers: major, minor, and patch. For example, version 1.2.3 indicates major version 1, minor version 2, and patch version 3. Update these numbers based on the changes you make to the library.

What are some common practices for managing library dependencies?

Common practices include using package managers like vcpkg or Conan, specifying version ranges in your project files, and regularly updating dependencies to avoid security vulnerabilities.

Can you give an example of a versioning scheme?

Sure! A common versioning scheme is Semantic Versioning (SemVer). For instance, if you release a new feature that is backward compatible, you would increment the minor version (e.g., from 1.0.0 to 1.1.0). If you introduce breaking changes, you would increment the major version (e.g., from 1.0.0 to 2.0.0).
