How to fix "Expression result unused" warning in C++ LLVM compiler?

Question

C++ / C#

cin;

Assign the answer to a variable, and then just use it like that ... well, you yourself understand, complete imbecility. And to see a yellow warning is not a hunt, and according to the rules this should not be. How to get out of the situation?
