There is no DataType called String in C++.
String can be created using character array and delimited by
null character i.e. '/0'.
like char name[]={'n','i','t','h','i','n','
','d','e','v','a','n','g','0'}
or
char name={"nithin devang"}//it will automaticall append
null char.
Null character is having value (ASCII) Zero. (0 character
dont have ascii value 0)
--
If you still wish to use the keyword string you may declare
a macro
#define String char[];
my answer surety %=98%

Answer / ganesh chincholkar
Yes true string is not a datatype in C++ but it is implemented through Standard Template Library. And the string class has dynamic memory allocation.
eg:-
string str;
cin>>str;
string str gets dynamically allocated storage and that storage size is not permanent and can be modifies later.
after:
what happens behind screen is actualy:
string str = new char[strlen(str) + 1];
when you take input of the string str its size is calculated and you get the desired meomry.
