String program problem

[ztein]

The program asks the user to enter his or her first name and then last name, and
that then constructs, stores, and displays a third string consisting of the user’s last name, followed by a comma, a space, and first name. I'm using string objects and methods from the string header file.

But it issues the following error during the compilation:

#include <iostream>
#include <string>

int main()
{
	using namespace std;
	string firstName;
	string lastName;
	cout << "Enter your first name: ";
	getline(cin, firstName);
	cout << "Enter your last name: ";
	getline(cin, lastName);
	string * fullName = new string;
	strcpy(fullName, lastName);
	strcat(fullName, ", ");
	strcat(fullName, firstName);
	cout << "Here's the information in a single string: " << fullName << endl;
	system("pause");
	return 0;
}

What's up with that?

[bluezor]

Do you really need to use a new string?
It works if you just use a regular string for fullName;

Don't use strcpy and strcat they are meant for char*.
Use the std::string operators = and + instead.
And bluezor is right don't create a new string.
