How can I debug templates in C++20?
Debugging templates in C++20 can be tricky due to their complexity. You can use static assertions, type traits, and the new concepts feature to help identify issues.
What are static assertions and how do they help?
Static assertions allow you to check conditions at compile time. If the condition fails, it generates a compilation error, helping you catch template errors early.
Can you give an example of using concepts for debugging?
Sure! You can define a concept to constrain template parameters. If a type doesn't meet the concept's requirements, it will fail to compile, making it easier to identify the issue.
What tools can I use for debugging C++ code?
You can use tools like GDB, Valgrind, or IDEs like Visual Studio and CLion, which have built-in debugging support.
