Compiled program not showing up as compiled and not able to run.
I recently had to reinstall ubuntu and now when I go to where my programs are in the command line they will not run. Normally once ls shows the list they are a different color to mark that it is a program. It does not even do that. It does show a different color for the files, just not for the programs. Also, these programs ran fine before and I just copied everything onto a hard drive and then put it back. So when I do ./program it says bash: ./program: Permission denied. Any help would be greatly appreciated. Also, how do I get a.out? Thanks
