Explanation by: Chandani

str1 is initialized with the characters and there are only 5 characters. Thus, the length of the str is 5. While, str2 is initialized with the string "Hello", when we initialized the string in this way - a null ('\0') character is inserted after the string. Thus, the length of str2 is 6.
