File Opening Modes in C and File Copying
In C, you can open files in various modes, each serving a specific purpose:
File Opening Modes
- “r”: Opens a file for reading. The file must exist.
- “w”: Opens a file for writing. If the file exists, it’s truncated; if it doesn’t exist, a new file is created.
- “a”: Opens a file for appending. Writing operations append data to the end of the file.
- “r+”: Opens a file for both reading and writing. The file must exist.
- “w+”: Opens a file for reading and writing. If the
