CHAPTER 1 GENERAL
<1> Declaration of type and storage class
The data type and storage class of an identifier that indicates a data object are declared. For details, see
CHAPTER 3 DECLARATION OF TYPES AND STORAGE CLASSES.
<2> Operator and expression
These are the statements that instruct the compiler to perform an arithmetic operation, logical operation,
assignment, etc. For details, see CHAPTER 5 OPERATORS AND EXPRESSIONS.
<3> Control structure
This is a statement that specifies the program flow. C has several instructions for each of the control
structures such as Conditional control, Iteration, and Branch. For details, see CHAPTER 6 CONTROL
STRUCTURES OF C LANGUAGE.
<4> Structure or union
A structure or union is declared. A structure is a data object that contains several subobjects or members
that may have different types. A union is defined when two or more variables share the same memory. For
details, see CHAPTER 7 STRUCTURES AND UNIONS.
<5> External definition
A function or external object is declared. A function is one element when a C language program is divided
by a special-purpose or characteristic action. A C program is a collection of these functions. For details,
see CHAPTER 8 EXTERNAL DEFINITIONS.
<6> Preprocessing
This is an instruction for the compiler. #define instructs the compiler to replace a parameter that is the same
as the first operand with the second operand if the parameter appears in the program. For details, see
CHAPTER 9 PREPROCESSINGS (COMPILER DIRECTIVES).
<7> Declaration of function prototype
The return value and argument type of a function are declared.
