1) SizeOf(s1) will give you 6
2) SizeOf(s2) will give you 5.
1) Sizeof function will count the number of characters (5) + the null terminated character at the end of every string (1), hence answer is 6 .
2) As s2 is a character array and NOT a string, the sizeOf function will count the number of elements in the array and hence will return 5.
