fgets prototype :char * fgets(char *str,int n,FILE *fp)
fgets reads n-1 characters or till it encounters \n in input whichever comes firsts
fgets reads n-1 characters or till it encounters \n in input whichever comes firsts

Function fgets(char *s,int n ,FILE char *stream)
It stop when it read n-1 char or a newline whichever come first.
Hence in the given question it read only 4 char.

In the file the 7th character is 'N' and fgets reads n-1 character.so r is not printed.After 7 character,str gets the null character and stoped. So the remaining 4 will be printed.
