User-input not working

[Serejai]

I'm trying to do the tutorials, but I can't get past the first part because my input variables aren't working. Here's my code:

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

I've looked at it a thousand times... it's character for character with what's on the website. But when I run the program, it prompts for a number, I input one, press enter, and it closes. What am I doing wrong?

try...

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

That worked for me.. (Using Dev C++)

It closes because there's nothing telling it to stop after it finishes the last cout line. Simply place a system("PAUSE"); right before return 0; and after cout<<"You entered "<<thisisanumber;.

So it would be:

#include <iostream>
int main ()
{
    int thisisanumber;
    cout<<"Enter a number:";
    cin>>thisisanumber;
    cout<<"You entered: "<<thisisanumber;
    system("PAUSE");
    return 0;
}

You could also place a few endl's after the cout's to make it look more organized. For example:

cout<<"Enter a number:"<<endl;

So instead of running the program to show:
Enter a number: _
(the underscore is the little blinky thingamajig*

It would look like this with endl:
Enter a number:
_

system("PAUSE") has several drawbacks, and does not offer any advantage over the other solutions.

Since this is the C++ forums, we'll be assuming Serejai is using C++ He should use this method, as suggested by the FAQ.

#include <iostream> 
 
int main(void)
{
std::cout <<"Press [Enter] to continue" <<std::endl;
std::cin.get();
return(0);
}

Apoc's method also works, but it is more for the C audience.

edit: And to add my personal opinion, it is better to have the cursor immediately in front of the prompt. That's the way most console apps do it.

Ty ^_^:; Sorry about not searching FAQs and such. I don't like searching for "related" topics, because my exact problem/experience probably isn't the same as somebody elses. Appreciate all the input.

I don't like searching for "related" topics, because my exact problem/experience probably isn't the same as somebody elses.

This couldn't be further from the truth. Every time a beginner comes to these forums, they ask the exact same questions. I have seen this particular question maybe 30-40 times. Always search the forums first.
