File Streams and FILE Pointers
A file stream in C is an abstract connection between your program and an external file or device, such as a disk file, keyboard, or screen. This stream allows you to perform input and output (I/O) operations on files in a consistent and controlled way. When you use file streams, you can read data from files or write data to files without worrying about the details of how the data is actually stored or transmitted.
FILE *file;
The FILE pointer is a special type in C used to represent and manage file streams. It acts as a handle or reference to an open file, allowing you to perform various operations such as reading, writing, or closing the file. When you open a file using functions like fopen, you receive a FILE * pointer. You then use this pointer in other file-related functions to specify which file you want to interact with. This approach keeps file operations organized and prevents confusion between different open files.
The FILE structure and its associated functions are defined in the standard header file stdio.h. You must include this header in your C programs to work with files.
