Answer 2

when you enter string whose length is greater than or equal to 7 characters it will copy 6th and 7th character to the string d at d[0] and d[1] repectively and at d[2] we are assigning NULL character which indicates the end of the string so when you print d it will only print upto 2 characters.

Answer 3

If the end of the source string (which is signaled by a null-character) is found before num(here 15) characters have been copied, destination is padded with zeros until a total of num characters have been written to it.

so when you print destination string it will print only till null encoutered.
