You can store a single ASCII character in a variable of type "char". All other basic types are for storing numeric data (double, float, long, short, int). You can also use the char type in conjunction with arrays in order to store strings, i.e.:
char myname[9] = 'Gsibbery';
Variables of type char must be enclosed in single quotation marks as I have above.
What in particular don't you understand about it?
