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 :D
 

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.

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

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

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.
