1.
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);
fgets reads characters from stream into the string s. It stops when it reads either n - 1 characters or a newline character, whichever comes first.
Therefore, the string str contain "I am a boy\n\0"

Considering all your explanations about \r.
What will str contain if file contains: "india\rbix"?

Reads characters from stream and stores them as a C string into str until (num-1) characters have been read or either a newline or a the End-of-File is reached, whichever comes first.
A newline character makes fgets() stop reading, but it is considered a valid character and therefore it is included in the string copied to str.
A null character is automatically appended in str after the characters read to signal the end of the C string.

Depends on the OS guys. In windows, the line break is \r\n but in linux the line break is \n. So when it reads \r, it automatically understands that it has reached end of line and hence stops further input. GCC must have done the same to allow consistency between various OSes. Not sure though.

Everyone wrote whatever is already known, but the question is still unanswered. Why the hell \r didn't get stored while \n does!
Anyone. Give the to 'to the point answer' plz!

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?
