C read file until eof

File handling in C is the process in which we create, open, read, write, and close operations on a file. C language provides different functions such as fopen(), fwrite(), fread(), fseek(), fprintf(), etc.

to perform input, output, and many different C file operations in our program.

Why do we need File Handling in C?

So far the operations using the C program are done on a prompt/terminal which is not stored anywhere.

The output is deleted when the program is closed.

But in the software industry, most programs are written to store the information fetched from the program. The use of file handling is exactly what the situation calls for.

In order to understand why file handling is important, let us look at a few features of using files:

• Reusability: The data stored in the file can be accessed, updated, and deleted anywhere and anytime providing high reusability.
• Portability: Without losing any data, files can be transferred to anotherin the computer system.

  The risk of flawed coding is minimized with this feature.

• Efficient
