C++ Primer Plus Chapter 4 Exercise 4

c plus plusWith 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;
cout << "Enter your last name: ";
cin >> lastName;

// Using C++ string member functions
str.append(" , ");

cout << "Here's the information in a single string: " << str << endl;

return 0;
