Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object.
Ruby string concatenation.
String objects may be created using new or as literals.
So string concatenation creates 2 more string objects even in our simple example.
If the given object is an integer then it is considered a codepoint and converted to a character before concatenation.
A string is a sequence of one or more characters that may consist of letters numbers or symbols.
A nice to meet you b c do you like blueberries a b c nice to meet you do you like blueberries you can use the operator to append a string to another.

If a match is found the sequence is returned otherwise nil is returned.
Fragments of a ruby string can be accessed using the method of the string class.
In this case a b c creates a new string.
The operator returns a new string which now is ada.
You ll use strings in almost every program you write.
0 13 we ll show you how to do string concatenation in our main program 0 18 in a bit but first let s try it out in a different way.
