What Is The File? Explain The Modes Of Files.

3 years ago

C Programming

File:- A file is an object which stored data or information. In computer, the data used in the future we will require a file. Because the ram is volatile the data is lost but the file is stored. In a room memory and store our data for a long time.

Modes Of Files

We can use one of the following modes in the open () function.

Mode	Description
“r”	Open for reading. If the file does not exist, fopen() returns null.
“RB”	Open for writing. If the file does not exist, fopen() returns null.
“w”	Open for writing. If the file exists, the content will be overwritten.
“wb”	Open for writing in binary. If the file exists, the content will be overwritten.
“a”	O pen forappendd. If the file does not exist, it will be return created.
