Question

I have a c program

#include <stdio.h>

int main ()
{
  printf("Hello");
}

On Windows:

I compile that program on windows and get a.exe

Now when I double-click on a.exe

Command windows opens

a.exe is run

and automatically close that windows.

To overcome this i have two solution

1> Create a batch file with the following content:

a.exe
pause

2> or add getch() function in my code

On LINUX

Now i want the same thing to happen in linux

I have compiled that program on linux get a.out and whenever i click on that nothing happens?

I have made one shell script:

#!/bin/bash

./a.out &

pause

and run that script by clicking on it but still nothing happened?

Answer 1

The thing you’re not seeing is that it won’t open in anything at all; the program will just execute quietly in the background.

To make the output visible, you’ll need to make a shell script to run the program in a terminal, which can be as simple as this:

#!/bin/bash
gnome-terminal -x "`dirname \"$0\"`"/a.out

Mark the script as executable, and now you should be able to double-click it and see your program open in a terminal window. Note that tying the program to a particular terminal emulator (like gnome-terminal) is probably a bad idea, and you should rethink why you want this behaviour.
