Answer: Option
Explanation:
Declaration: char *fgets(char *s, int n, FILE *stream);

If we are writing.
printf ("hello\n welcome");
Output will be:
Hello.
Welcome.
But when we a are writing.
Printf ("hello\n");
Why? Hello\n is printed.
I mean this time \no is also printed.
Why? Please explain.
printf ("hello\n welcome");
Output will be:
Hello.
Welcome.
But when we a are writing.
Printf ("hello\n");
Why? Hello\n is printed.
I mean this time \no is also printed.
Why? Please explain.

Hi,
If \r is in printf () then the the characters after it are printed first, now let the number of characters printed till now is N then the first n characters are skipped and following characters are printed upto \r.

In this program,
\r same like \0.
So output print to \r .
And cursor automatically go new line,
That wise \n is must print in c this is rule in C "I am a boy\n\0" is output.
\r same like \0.
So output print to \r .

@Sundar. Please, explain again.
printf("india\rBIX") should print india since you said the control shifts to a leftmost position that is i?
