What are the benefits of using consts in C++ headers?

Using consts in C++ headers helps improve code readability, maintainability, and can also enhance performance by allowing the compiler to optimize better.

Can you give me an example of how to declare a const in a header?

Sure! You can declare a const in a header like this: const int MAX_SIZE = 100; This makes MAX_SIZE a constant that can be used throughout your program.

Are there any downsides to using consts in headers?

One downside is that if you change the value of a const, you need to recompile all files that include the header, which can slow down the build process.

How does using consts affect memory usage?

Using consts can help reduce memory usage since they are typically stored in read-only sections of memory, preventing unnecessary copies.
