Working with files in C involves performing operations like opening, reading, writing, and closing files. Here's an overview of the basic steps involved: 1. Include the necessary header file: - To work with files in C, include the `<stdio.h>` header file at the beginning of your program. It provides functions and definitions for file operations. 2. Declare a File Pointer: - Declare a file pointer variable to store the reference to the file you want to work with. For example: ```c FILE *filePointer; ``` 3.
