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"

@Nayna
Let us know the difference between the \r and \n.
\r - is moves the cursor to the left-most position of the CURRENT line.
\n - is moves the cursor to the left-most position of the NEXT line.
Example:
1. printf("India\rBIX");
Output: BIXia
2. printf("India\nBIX");
Output:
India
BIX
Note: It may not work as I said in 32-bit platform. But works fine in Turbo C (under DOS 16-bit platform).
Hope the understand the difference. Have a nice day!

Hello guys!
I hope you are doing well.
1. Well there is fputs() Function in C which reads string in the format of "\r\n"
2.But at the time of reading fgets() function reads only "\n"...Not like previously... "\r\n"
3. And \0 is there just because In C string always ended with null (\0) character.
