1. varchar is non unicode and char is unicode character datatype
2. char is ‘n’ bytes whereas varchar is actual length in bytes of data entered in terms of storage size
3. varchar is variable in length and char is the fixed length string
4. For varchar, if a string is less than the maximum length then it is stored in verbatim without any extra characters while for char if a string is less than the set length it is padded with extra characters to equalize its length to given length
static void Main(string[] args)

string s1 = "Delhi";
string s2;
s2 = s1.Insert (6, "Jaipur");
Console.WriteLine(s2);
}c = s1.CompareTo(s2);
