In c++, is a string considered a data type?

Question

For instance
what type of data type is the string "middleName" ?
Thanks in advance

Answer 1

I'm surprised that nobody gave you a very good answer.



There's two ways to represent strings:



1) C-strings

These are char arrays. Of course a char is a data type.



2) the class

C++ also has a class In this case a string is an object of this class.

Answer 2

string is the name of a data type in C++ (to be pedantic, it is an typedef alias to the template specialization std::basic_string)



however "middleName" does not name a type. It is a string literal, which is an instruction to the compiler to create a nul-terminated array of char in the read-only section of the program's data segment, initialized with the characters "middleName" with NUL (character '\0') added at the end. When a string literal is used in an expression, it evaluates to the pointer to the first character in the array. That pointer has the type const char*.

Answer 3

It's a char array in native C++ (char *). However, many class libraries will include a String class of some type that will help you to extract substrings, etc.

Answer 4

Yes and know.... The C++ specification does not contain the keyword string, as I remember However you can create your own data type though classes and name it string. :D

Answer 5

Its a char. Example :

char *mn = "middleName";
