title: How to implement "press to enter＂in c++
body: <p>any idea on how to implement a "press any key to move on" in c++?</p>
  
  <p>Based on my understanding, for any input stream function, it all requires users to hit "enter" to read.</p>
  
  <p>But how do I make it like “whenever a key is being hit, it moves on to the next stage without hitting the enter key?"</p>
  
  <p>By the way, the working station is Linux</p>
  
  <p>Thanks a lot</p>
