OPERATOR:  string:  +  +=
The string operators are used to join strings together. This is referred to as concatenation.
 
Note the String library contains several useful functions for manipulating strings.
 
There are two string operators:
 
 + 
The + operator joins two strings together to create a third string. The second string is simply added directly onto the end of the first string. No extra characters or blank spaces are automatically added. (You may wish to add blank spaces for appearance.)
 
 += 
The += operator modifies a string by joining a second string onto the end. The new string contains both strings.
