@guptashubham210a thats because s1 actually stores only 5 characters but when printed it starts from 0 and keep printing until null encountered so all the garbage elements are not actually stored in s1.

#3

it should be -2 na because last char will be \0 and index starts from 0 so n-1 index and -1 for \0? so n-2

@guptashubham210a
suppose a is hello
so strlen(a) is 5
indexing start from 0 so it should be -1 only

#5

what about \0? so it should be 6 na? or it does not count \0?

@guptashubham210a no it does not count it you can try it on your own also ( try cout strlen)
