Detecting Enter Key?

[Code Assassin]

Hello,

How would you make a program detect when the user enters the enter key. I don't want the exact answer, just a hint to nudge me in the right direction.

Thanks.

If it's a console app then using 'cout.get()' will wait untill the enter key is pressed

I've tried that and it's not working. Any other suggestions?

There are some good tips in here for keeping the console open, not sure if it's specifically aimed to the enter key or not.

I think I've found what I've been looking for :

cout << "Press ENTER to quit.";
  cin.ignore( numeric_limits<streamsize>, '\n' );

Thanks.

EDIT: This code doesn't work either. How do you do it!?

Any other suggestions for making cin detect when a user inputs the Enter Key.

Have you tried cin.get()?

Thanks for your reply. I'll see if it works...

apparently the cin.get() works

cout << "Press the ENTER key";
  if (cin.get() == '\n')

Here it is. Very simple:

#include <iostream>
#include <cstring>
#include <cmath>

using namespace std;


double get_key();


int main(){
    
    
    double n;
    
    
    
    while(true){
                
                cout << "Input number to get square root: "<< endl;
                
                n = get_key();
                
                if(n == 0.0){
                     break;
                     }
                     
                     cout << "Result: " << sqrt(n) << endl;
                     
                     }
                     
                     system("PAUSE");
                     return 0;
                     
                     }
                     
                     
                     double get_key(){
                            char lenght[100];
                            
                            cin.getline(lenght, 100);
                            if(strlen(lenght) == 0.0)
                                          return 0;
                                          return atof(lenght);
                                          
                                          }
