What is the difference between using string type and char[] type to store a name?

Question

In terms of Performance, Effectiveness? Anything? and what are the good practices?

Answer 1

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.

Answer 2

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.

Answer 3

Martin Taylor I know I'm not talking about only c++ I posted just general answer.

Answer 4

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.
