Random File Processing in C Using ftell(), fseek(), and rewind():

Random file processing in C enables efficient navigation and manipulation of files by accessing specific file locations without sequential reading. This is achieved using functions like ftell(), fseek(), and rewind().

- ftell(): Determines the current position of the file pointer in the file stream. It returns a `long` integer indicating the byte offset from the beginning of the file.
- fseek(): Moves the file pointer to a specific location. You can set the pointer to an absolute position, move it relative to the current position, or seek from the end of the file, offering flexibility for reading or writing operations.
- rewind(): Resets the file pointer to the beginning of the file. It is a simpler alternative to fseek() when the goal is to start over from the beginning.

These functions are essential in scenarios requiring non-linear file access, such as updating records in a binary file, reading specific data chunks, or implementing file-based databases. Mastering these functions enhances file manipulation capabilities and optimizes program efficiency.
