Help with vanishing screen

I posting this message seeking some assistance on an issue I am experiencing. I have been helping a friend with writing C programs as he is currently in school. I have taken C a while ago, and I experienced this same problem. However, I do not remember what the fix is.

Problem:

I am using Borland C++ for my compiler. The programs compile fine with no errors. When I run the program, the screen comes up asking for the user's input. I type the input, press enter, and the screen immediately disappears. When I took the class, I used fflush() or getchar(). I have tried these functions and they don't solve this problem. From previous conversations with more experienced C programmers, I realize that using fflush is not a good programming practice. Therefore, I would rather learn the right way.

Unfortunately, I do not have the code handy to paste into this post, but if you need it, I can certainly add it later this evening. I would like to mention that it does this on all the C programs I have attempted to compile and run on two different high powered computers. If you need any additional information, please let me know.

I am hoping it might just be a setting with the Borland software or some kind of C function I can add that will prevent this from happening.

I think what you are describing is your program asking for input and then displaying the answer, but closing before you can read anything. To fix this try adding the system("pause") like this:

Code:

---

int main(void)
{
  //code here
  system("pause");
  return 0;
}

---

This way, before you program exits it will pause and say press any key to continue.

Thanks for the suggestion. What you described is exactly the problem I am experiencing. I will certainly try adding that code to see if that will delay the termination so I can view the results.

Make sure to post in the right forum next time. This is not a game programming question.

I apologize Lurker for posting in the wrong forum. I was reading the game programming forum and forgot where I was when I posted.

I have another suggestion just in case Sean's doesnt work.

Since you are using Borland C++, you might want to consider conio.h. Borland put a function in there called getch() which acts similar to getchar().

Just throw in a getch() and it should do the trick:

int main (void)
{
....code....

getch();
return 0;
}

Thanks for the suggestion DavidP. I will give this a shot as well. I do appreciate the response.
