Revisiting the concept of arrays - Strings vs. Char Arrays

Review the following code:

string hello1 = "hello!";
char[] hello2 = new char[10]{'h','e','l','l','o','!','','','',''};

hello1 = "Hi!";

hello2[1] ='h';
hello2[2] ='i';
hello2[3] ='!';

int len1 = hello1.Length;
int len2 = hello2.Length;

Speak to the ramifications of this code and how strings are handled vs. how arrays of char are handled - declared, initialized, modified. What does this mean for how you use these particular language constructs?

Explanation / Answer

From the question :

string hello1 = "hello!"; // hllo1 is a string variable which stores hello!

char[] hello2 = new char[10]{'h','e','l','l','o','!','','','',''}; // It is arrays of char hello2 contains hello!

hello1 = "Hi!"; // hello1 data modified with Hi!

hello2[1] ='h'; // hello2[1] contains h
hello2[2] ='i';   // hello2[2] contains i
hello2[3] ='!';   // hello2[3] contains !

int len1 = hello1.Length; // Here length is 3
int len2 = hello2.Length; // Here length is 10
