Honestly I would split the tags in 2, As agreed with @
Future C# and C++ isn't the same and currently most of the Tutorials or Threads that get made don't even have that current tag, they have individual tags.
I'dd also agree with the fact that its better to devide them as not every programmer knows the diffirence.. We can see the diffirence in syntax for C# and C++, but someone who's new to programming might not know that and confuse himself and give bad suggestions/feedback on the thread from the OP.
