Yes, that's correct. One example of accidental name conflict with macros in C++ could be when a macro is defined with a name that conflicts with a function or type name from a library or the standard library. For instance, if a macro is defined with the name `max` in a C++ program that uses the `algorithm` header from the standard library, it could conflict with the `std::max` function defined in that header, leading to unexpected behavior or errors.

Similarly, if a macro is defined with a name that matches a variable or function name in the current scope, it could override that name and cause unintended behavior. This could be especially difficult to find and debug in large codebases.

In contrast, using constexpr to define constants avoids these kinds of name conflicts since they are evaluated by the compiler at compile time and are treated as regular variables in the program's scope.
