In c++ can we input something without printing it on screen and also how to clear screen in iostream?

Question

I use cin and it always prints the value which is inputted.Is there any way to input any value without showing in on screen? Like-
cout<<"press any key to exit";
cin>>key;
return 0;
//I dont want to see the input of cin on the screen
.Any alternatives?
