(1) Basic types
Basic data types are also referred to as “arithmetic types”. The arithmetic types consist of integral types and
floating-point types.
(a) Integral types
Integral data types are subdivided into four types. Each of these types has a value represented by the
binary numbers 0 and 1.
• char type
• Signed integral type
• Unsigned integral type
• Enumeration type
(i) char type
The char type has a sufficient size to store any character in the basic execution character set. The
value of a character to be stored in a char type object becomes positive. Data other than characters is
handled as an unsigned integer. In this case, however, if an overflow occurs, the overflowed part will
be ignored.
