With some minor adjustments, we can use the C++ string class to accomplish our goal. We will use the C++ member function ‘append’ from the string class. My solution if fairly clean and simple. Here is the source:
4. Write a program that 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. Use string objects and methods from the
string header file. A sample run could look like this:
Enter your first name: Flip
Enter your last name: Fleming
Here’s the information in a single string: Fleming, Flip
#include <iostream>
#include <string>
using namespace std;
int main()
{
string firstName;
string lastName;
string str;
// Gather input, could use cin.getline here.
cout << "Enter your first name: ";
cin >> firstName;
cin.ignore();
cout << "Enter your last name: ";
cin >> lastName;
// Using C++ string member functions
str.append(lastName);
str.append(" , ");
str.append(firstName);
cout << "Here's the information in a single string: " << str << endl;
cin.get();
return 0;
}
