Working with Binary Files

Binary files store data in raw format, which allows efficient reading and writing without converting data to text.

In this lesson, you will learn:

• How to write data to a binary file using fwrite().
• How to read data from a binary file using fread().
• The difference between binary and text file handling.

Opening a Binary File

Binary files are opened using the fopen() function with a mode containing b.

Example:

FILE *filePtr = fopen("data.bin", "wb");

This opens data.bin for writing in binary mode.
