How to Declare a String in C++

C style strings can run the risk of buffer overruns.

One useful class in the C++ standard library is the string class. The string class was designed as a safer and easier alternative to the so-called "C style" strings, or char arrays. C++ strings do not run the risk of accidental buffer overrun, can expand themselves as needed, and provide a set of functions to edit and search through themselves.

Instructions

Add the std Namespace

1. Add the std namespace with the "using" keyword. For example, type:

   using namespace std;

2. Declare a string, optionally using a constructor to assign a starting value. For example, type:

   using namespace std;

   string example_string;

   string constructor_string("This is the string's text.");

3. Assign values to strings as you would other variables. Strings can be added to each other and assigned using the normal +, = and += operators.

   using namespace std;

   string example_string;

   string constructor_string("This is the string's text.");

   example_string = "This is the string's assigned value.";

   example_string += " This text was added to the string's original value."
