What is file
A file is a container in computer storage devices used for storing data.

Why files are needed?
When a program is terminated, the entire data is lost. Storing in a file will preserve your data even if the program terminates.
If you have to enter a large number of data, it will take a lot of time to enter them all. However, if you have a file containing all the data, you can easily access the contents of the file using a few commands in C.
You can easily move your data from one computer to another without any changes.

What are file operations in C/C?
Creating a new file
Opening an existing file
Closing a file
Reading from and writing information to a file

Working with files

When working with files, you need to declare a pointer of type file. This declaration is needed for communication between the file and the program.

FILE *ptr;

Hashtags :
