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."
