how to initialize string pointer?

Question

I want to store the static value in string pointer is it posible?

If I do like

string *array = {"value"};

the error occurs

error: cannot convert 'const char*' to 'std::string*' in initialization

Answer 1

you would then need to write

string *array = new string("value");

although you are better off using

string array = "value";

as that is the intended way to use it. otherwise you need to keep track of memory.

Answer 2

A std::string pointer has to point to an std::string object. What it actually points to depends on your use case. For example:

std::string s("value"); // initialize a string
std::string* p = &s; // p points to s

In the above example, p points to a local string with automatic storage duration. When it it gets destroyed, anything that points to it will point to garbage.

You can also make the pointer point to a dynamically allocated string, in which case you are in charge of releasing the resources when you are done:

std::string* p = new std::string("value"); // p points to dynamically allocated string
// ....
delete p; // release resources when done

You would be advised to use smart pointers instead of raw pointers to dynamically allocated objects.
