Answer 2

Answer:

To create a new file or open an existing one, use the fopen() function.

FILE*fp;

fp = fopen('abc','r');

Explanation:

The fopen() function has the following syntax:

fp = fopen(char filename, char mode); FILE *fp;

In this example, the pointer fp is of the FILE data type and points to an open or recently created file. The name of the file you want to open or create is the "filename" reference. The term "mode" refers to the reason the file is being opened.

Reading, writing, or adding data to a file are all possible modes. The standard input output library contains the fopen() function as well as all the other functions covered in this lecture.
