If name in C++ is not fully qualified, e.g. std::cout, it can lead to an unintentional error, such as mentioned at https://en.cppreference.com/w/cpp/language/qualified_lookup. But using a fully qualified name for ::std namespace, e.q. ::std::cout, is very rare, as I have noticed.
I want to programmatically get a list of available functions in the current MATLAB namespace, as well the available functions in a package. How can this be done?
So I know any header from the C Compatability Headers:Places in the global namespace each name that the corresponding cxxx header would have placed in the std namespace
I have some well-formed code looks like this:So, is there any portable tricks by using the NAMESPACE_BEGIN() macro to obtain namespace name "Foo" in test()?
Is this standard in C++? In C#, I liked declaring nested namespaces like this:The alternative was this, which is a little uglier:
We already know that Function arguments used to have the limit of 255 explicitly passed arguments. However, this behaviour is changed now and since Python-3.7 there's no limit except sys.maxsize which is actually the limit of python's containers. But what about the local variables?
