short int
int
long int
double
float
char
these are all datatypes
a data types is a type of sytem
Composite datatypes are the datatypes which can be constructed with in a program by using prmitive datatypes and other composite types.the act of constructing a composite data type is called composition..............

there are many predefined words in c.. some are void,datatypes,printf,scanf etc
No Primitive data types do not have objects. As of Java 1.5, all primitive types in Java have "wrapper" classes. These classes serve two purposes: # They keep all type-specific methods together in one place. # They allow primitive types to be used in situations which take advantage of generics (also introduced in Java 1.5).
char: A one-byte integer with implementation-defined signedness.signed char: A signed one-byte integer.unsigned char: An unsigned one-byte integer.wchar_t: A wide character of implementation-defined size and signedness.short: A signed integer with at least 16 bits.unsigned short: An unsigned integer with at least 16 bits.int: A signed integer with at least 16 bits.unsigned int: An unsigned integer with at least 16 bits.long: A signed integer with at least 32 bits.unsigned long: An unsigned integer with at least 32 bits.long long: A signed integer with at least 64 bits.unsigned long long: An unsigned integer with at least 64 bits.float: A floating-point number with 32 bits of precision.double: A floating-point number with 64 bits of precision.long double: A floating-point number with 80-96 bits of precision.
The usual C datatypes, nothing special.
Composite datatypes are the datatypes which can be constructed with in a program by using prmitive datatypes and other composite types.the act of constructing a composite data type is called composition..............
structure is a collection of dissimilar datatypes whereas array is collection of similar datatypes.....

In different languages we have different datatypes . Like in c++ we have int for integers , string for strings . In database we have datatypes, number for storing integer and varchar2 for storing string or characters.Like in languages like c we have datatypes such as char for characters , int for integers etc . In database we have datatype to denote the type of the field example numbers for storing integer, Varchar for characters.
One of the built-in datatypes.
Class Object Message
structure is a collection of variables of different datatypes.
There are far too many to provide a comprehensive list -- and new datatypes are being created all the time. However, datatypes can be split into two broad categories: built-in types and user-defined types. The built-in types include all the primitive datatypes inherited from C (including int, long, short, char, float, etc), which can be signed or unsigned and are often called intrinsic types. Built-in types also include the containers found in the standard template library (STL), including string, vector and list, along with their associated iterators. To make use of the STL types, you must include the appropriate library headers. User-defined types are those you define yourself, typically class, struct or union definitions, as well as enums and typedefs. User-defined types also include those types provided by a third-party, excluding the built-in types. Since user-defined types are not strictly part of the language, and new types are created every day, it would be impossible to list them all.
Char is fixed length, while Varchar is variable length.
all the three are user defined datatypes
Array is not a struct. Array only has one datatype, struct has arbitrary different datatypes.
