-string
-======
-
-Description
------------
-
-Text strings can be represented in two ways. you can use the String
-data type, which is part of the core as of version 0019, or you can
-make a string out of an array of type char and null-terminate it.
-This page described the latter method. For more details on the
-String object, which gives you more functionality at the cost of
-more memory, see the
-`String object <http://arduino.cc/en/Reference/StringObject>`_
-page.
-
-
-
-Examples
---------
-
-All of the following are valid declarations for strings.
-
-::
-
-      char Str1[15];
-      char Str2[8] = {'a', 'r', 'd', 'u', 'i', 'n', 'o'};
-      char Str3[8] = {'a', 'r', 'd', 'u', 'i', 'n', 'o', '\0'};
-      char Str4[ ] = "arduino";
-      char Str5[8] = "arduino";
-      char Str6[15] = "arduino";
-
-
-
-**Possibilities for declaring strings**
-
-
-
-
--  Declare an array of chars without initializing it as in Str1
--  Declare an array of chars (with one extra char) and the compiler
-   will add the required null character, as in Str2
--  Explicitly add the null character, Str3
--  Initialize with a string constant in quotation marks; the
-   compiler will size the array to fit the string constant and a
-   terminating null character, Str4
--  Initialize the array with an explicit size and string constant,
-   Str5
--  Initialize the array, leaving extra space for a larger string,
-   Str6
-

-
-**Null termination**
-
-
-
-Generally, strings are terminated with a null character (ASCII code
-0). This allows functions (like Serial.print()) to tell where the
-end of a string is. Otherwise, they would continue reading
-subsequent bytes of memory that aren't actually part of the
-string.
-
-
-
-This means that your string needs to have space for one more
-character than the text you want it to contain. That is why Str2
-and Str5 need to be eight characters, even though "arduino" is only
-seven - the last position is automatically filled with a null
-character. Str4 will be automatically sized to eight characters,
-one for the extra null. In Str3, we've explicitly included the null
-character (written '\\0') ourselves.
-
-
-
-Note that it's possible to have a string without a final null
-character (e.g. if you had specified the length of Str2 as seven
-instead of eight). This will break most functions that use strings,
-so you shouldn't do it intentionally. If you notice something
-behaving strangely (operating on characters not in the string),
-however, this could be the problem.
-
-
-
-**Single quotes or double quotes?**
-
-
-
-Strings are always defined inside double quotes ("Abc") and
-characters are always defined inside single quotes('A').
-
-
-
-**Wrapping long strings**
-
-
-
-You can wrap long strings like this:
-
-::
-
-    char myString[] = "This is the first line"
-    " this is the second line"
-    " etcetera";
-
-
-
-**Arrays of strings**
-
-
-
-It is often convenient, when working with large amounts of text,
-such as a project with an LCD display, to setup an array of
-strings. Because strings themselves are arrays, this is in actually
-an example of a two-dimensional array.
-
-
-
-In the code below, the asterisk after the datatype char "char\*"
-indicates that this is an array of "pointers". All array names are
-actually pointers, so this is required to make an array of arrays.
-Pointers are one of the more esoteric parts of C for beginners to
-understand, but it isn't necessary to understand pointers in detail
-to use them effectively here.
-
-
-
-Example
--------
-
-::
-
-    
-    char* myStrings[]={"This is string 1", "This is string 2", "This is string 3",
-    "This is string 4", "This is string 5","This is string 6"};
-    
-    void setup(){
-    Serial.begin(9600);
-    }
-    
-    void loop(){
-    for (int i = 0; i < 6; i++){
-       Serial.println(myStrings[i]);
-       delay(500);
-       }
-    }
