The three most basic data types, character, integer, and floating point, are all covered in this chapter, along with the multiple variations and qualifiers that apply. Variable declarations, scope, and life are introduced in this chapter. The C typedef and enum are shown, as is the format of a C identifier and the C reserved key words.
