Thread: User Input

Say this is my code:

Code:

#include <iostream.h>
int main()
{
  int x;
  cout<<"Please enter a number: ";
  cin>>x;
  cout<<"You entered: "<<x;
  return 0;
}

When it says Please enter a number, how do I enter it? Say I put in a 1, then what do I press? If I press enter, the program will close... How do I fix it? Do I press something else?
I'm compiling with Dev-C++...

Read the FAQ.

while(cin.get() != '\n'); is a cheap way for pausing console apps. Keep in mind that the newline char may be present from your last call to cin, so you can also use cin.ignore(1); after cin >> x;

Can´t I predict when <b>get</b> will not remove the read character?

Thanks for the help, but it didn't work. Although, I did find a code that did work:

Hmm... works for me using dev-c.

Code:

#include <iostream>
using namespace std;
int main()
{ 
  char quit;  
  int x;
  while (quit!='q')
  {
    cout<<"Please enter a number: "<<endl;
    cin>>x;
    cout<<"You entered: "<<x<<endl;
    cout<<"Press q to quit "<<endl;
    cin>>quit;
  }

  return 0;
}

So, that works...

It's always a sense of accomplishment when you can find your own solution. Good work!
