I created a simple C program a while ago. It's a simple command-line generator that takes some number, prints the results and stops. I always ran it in the editor's command line enviroment that automatically paused after the program ran, so I omitted adding a getchar() at the end.
I now regret this, because I managed to lose the source. All I have now is the complied .o and .exe file, and the latter - of course - exits immediately after it prints the output, so it's unusable. It wasn't that long, about 100 lines, but I'd like to avoid rewriting it. (Also, I might even learn something new from this way.)
Now I have very basic knowledge of C, and about zero on computer-degree x86 assembly (though I learnt the basics of 8086-assembly for microcontrollers, it won't be that helpful now I guess), so I'm kinda stuck here. Can I either add that getchar() like pausing function to the complied code, or is there any way I can make that .exe stop before exiting while still keeping it standalone?
The program will run on a Windows 10 system.
I would write some sort of batch script in which you call your program and then just run pause, which waits for you to hit a key before it continues.
wrapper.bat:
yourprogram.exe
pause
Of course you can disassemble your executable into raw x86 assembly code, then look up the code for a simple getchar() on Windows, add that and reassemble. However, it would probably be less time consuming to rewrite the program, depending on how complex it was or just create a wrapper batch-script.
