In string data type and char[], there is no difference they both same. Char[] is basically an array of characters which make string and string data type is the array of characters so there is no difference. To define a string in c like languages we use char[] because there is no string data type but when c++ and java or other languages comes then they come with a dedicated string data type to create strings easily just using 'string' data type. In terms of performance char[] is faster than string. And also string is an immutable data type. While char[] can be updated.

Using char[] you can manage memory efficiently as it will store specific space for the array of strings whereas using string a specified space will be stored even if it is not filled.

Maninder $ingh I tend to believe that saying that a C-style string performs better than a C++ string,is nothing short of a myth. In what respect(s) is it better? I think that in most cases,the operations performed on a C++ string are faster than their C-style string counterparts.
