C++ strings

In the previous chapter we briefly mentioned strings and we learned that a string can hold alphanumeric data in anything from a single character to a whole book. We didn't look at declaring, initializing, or manipulating strings. So let's do that now.

Declaring strings

Declaring a string variable is simple. We state the type, followed by the name:

String levelName; 
String playerName; 

Once we have declared a string we can assign a value to it.

Assigning a value to strings

To assign a value to a string, as with regular variables, we simply put the name, followed by the assignment operator, then the value:

levelName = "Dastardly Cave"; 
playerName = "John Carmack"; 

Note that the values need to be enclosed in quotation marks. As with regular variables we can also declare and assign values in a single line:

String score = "Score = 0"; 
String message = "GAME OVER!!"; 

This is how we can change our string variables.

Manipulating strings

We can use the #include...
