C rewind() functionThe rewind() function sets the file pointer at the beginning of the stream. It is useful if you have to use stream many times. Syntax: Example: File: file.txt File: rewind.c Output: this is a simple textthis is a simple text As you can see, rewind() function moves the file pointer at beginning of the file that is why "this is simple text" is printed 2 times. If you don't call rewind() function, "this is simple text" will be printed only once.
