What does 'permission denied' mean? If you see the error message, it means that Terminal can't complete the command you're trying to run because it is unable to access the file you want to work on.
And as the name of the error suggests, it can't access the file because it doesn't have permission..
Conclusion.
The Bash permission denied error indicates you are trying to execute a file which you do not have permission to run.
To fix this issue, use the chmod u+x command to give yourself permissions.
If you cannot use this command, you may need to contact your system administrator to get access to a file..
For solving this error, you need to add the correct permissions to the file to execute.
However, you need to be a “root” user or have sudo access for changing the permission.
For changing the permission, Linux offers a chmod command.
The chmod stands for change mod..
Kill your running .exe application from the task manager.
i.e. for Windows press ctrl + alt + del -\x26gt; select your .exe application -\x26gt;press delete and then Enter key. for Linux versions type "kill PID" of your .exe application on the terminal and press Enter.
Now you can recompile you C++/c code using Dev C++..

Permission denied means you don't have permission to perform an attempted operation on a file.
This could mean things like trying to write to a read-only file or trying to execute a file not marked as executable..

One is that root owns the output file; the other is that absolutely nobody has permission to read the input file (except root, which is exempt from the permission system).
The easy answer is to just delete the output file, and to fix permissions on the input file with something like chmod 644 shell.c (no sudo needed).
If you receive another permission denied error, you can make it executable by doing chmod +x ex1.
Normally compilers are smart enough to set the executable bit by themselves. jeez i'm an idiot, I compiled but was running ex1.c not ex1, thanks! I just needed to do a fresh build and then it ran fine.
You can't just run a file with C code.
I still get permission denied! Step 1:
If gcc -o shell shell.c gave you a "permission denied" error, then you probably had a file named shell that you didn't have permission to overwrite.
If you had that problem before using sudo, then there's no way for us to tell how it happened.
Try removing the shell file ( sudo rm shell) rerun the ls command, then run gcc -o shell shell.c.
