[aersoy]

i have just started C programming actually 5 minutes ago

i use DEV C++ version 4.9.9.2

and my operating system is WinXP home edition SP2

i have created simple program as in the book but i cannot open the exe file

using the below source code

</pre>
#include<stdio.h>
/*function main begins program execution*/
int main ()
{
printf ("Welcome to C!\n");

return 0;
}
</pre>

but the exe file closes as soons as i open it

what should i do to solve this program?

thanx

You should execute the exe file in command line.
Not double click the exe file for executing. Then you will see the message"Welcome to C!"

Your EXE is a "Windows console application". If you launch it from Windows Explorer, Windows opens a command prompt window, runs your program until it exits, and then closes the command prompt window. That all happens super-fast, so you probably won't see your message.

As RDRyan suggests, you can manually open a Command Prompt window, and then run your program from the command line.

insert :
#include "conio.h"
and getch(); after return 0;

hi ITpro, i think the getch(); doesnt allowed in devC++, i tried it..

 

[ITpro]

Oh no , i still use it , if you use C++ syntax in dev C++ use must insert : using namespace std ; before main ()

You ay also try the following :
#include <conio.h>

then at the end of your program, write :

while(!kbhit());//this would pause the program till any key is pressed .

The best solution to this problem is to include:
system( "pause" );
as the last line of your code & immediately before return 0;
This will keep the DOS window open until you press a key.
This is documented in the Dev C++ help files.
