Answer Posted / kapil kumar verma iimt meerut

when we declare array of char it has to be terminated by
null but termination by null in case of string is
automatic.the compiler automatically puts a null char when
we insert a string for example "kapil" for the
string "kapil\0", but for a char array we need assign a
place for it for example a[6] contains five char & a null
char.& secondly
when char array is read through scanf() input function then
spaces are not allowed if characters is read as string
(through gets() function) spaces are allowedand are treated
as a single char.
