In a file contains the line "I am a boy\r\n" then on reading this line into the array str using fgets(). What will str contain?
Answer: Option
Explanation:
Declaration: char *fgets(char *s, int n, FILE *stream);

@Richard.
\0 is a default null character that will be stored automatically at the end of the file when we use file related functions in C.

And the question still remains the same. Why not ?
"\r\r\n" is stored and why not?
"\r\n" is returned?
"\r\r\n" is stored and why not?
"\r\n" is returned?

Hi dear.
I think the answer will be D, because newline return require.
For Linux \n.
For windows \r\n.
For mac os \r.

Yes @Suman.
But that overwrites 'ind' and changes it to 'bix' and hence the output.
