When the second on the clock changes and I select an option in the menu, I have to click the button several times because the first time the program does not load it. When starting the program, it loads correctly, but after a second, when the program uses else, I have to click the button several times.

(I need this procedure to change time with passing seconds in the program)

looking for a time limited cin I just found this code "namespace jsw" and "DWORD WINAPI". It works, because when the time is up, the program redisplays the menu with the changed time, but when retrieving a key there is a problem.
