valgrind: ./cache1.c: Permission denied

As an AI language model, I cannot access your file system or execute any commands on your local machine. However, I can provide you with some general information about this error message.

This error message indicates that Valgrind, a memory debugging tool, does not have permission to access the file cache1.c. This could be due to several reasons:

- The file may not exist in the specified directory.
- The file may be owned by another user, and Valgrind does not have permission to read or execute it.
- The file may be marked as read-only or executable only by the owner.

To resolve this issue, you can try the following:

- Check if the file exists in the specified directory.
- Ensure that Valgrind has permission to access the file. You can use the chmod command to change the file permissions.
- Run Valgrind as the owner of the file or with sudo privileges.

If the issue persists, you can try running Valgrind on another file or directory to verify if it is a permissions issue or a problem with Valgrind itself.
