Actually user defined data type made by user like array,structure,union,pointer. the data type which is define by user or programer according to his need is called user define data type and also called the programer define data type........

What is the need for structure datatype?
A structure is not a data type. We use structures to define new data types (user-defined data types). If we didn't have the ability to create user-defined types we'd be limited solely to the built-in data types and arrays of those types.
What are the two types of conversions for user defined data type?
The two types of convertion areImplicitExplicit
What is use of user defined data in c?
to create user defined functions the user defined data is needed nd its useful to the programmer to create its own data.
Difference between built in data type and user-defined datatype?
A built in data type is a framework's native data type. By default you'd probably have some built in generic data types, such as integer, string, boolean and so on. In the other hand sometimes you can extend the framework's data types, by programminga user-defined data type. In this data type you have to define it's behaviour and structure, and once defined, you can use it the same way you use the default data types. In PostgreSQL or Oracle, you can define data types. You can read about it on their webs.
What are the properties of data types?
When we enter a variable then we know it what type it belong ,but the compiler does not know it ,for knowing it we declare data types. Storage representations & machine instructions to handle constants differ from machine to machine.The variety of data types available allow the programmer to select the type appropriate to the needs of the application as well as the machine. ANSI C supports 3 types of data types 1.Primary data types 2.Derived data types 3.User defined data types JAVA has 2 types 1.In Built data types 2.User Defined datatypes
Is struct is user defined data type?
yes, a structure is a user-made data type so that user can manipulate multiple data types simultaneously. a structure covers up sum limitation of arrays as in it provides heterogenous data type.
What is data in link list?
Data in the link list could be anything, it could be user defined data types or standard data types. Like link list of a text file data could be list of strings.
Which data type can store any data?
There is no such data type. However, when we use user-defined data types of our own type, then that type of data can be stored in a variable. So as a term, you may say that user-defined data type can store any data. As the data-type used in any variable will be depending upon us.
What is the difference between basic data types and derived data types and user defined data types in C plus plus?
By basic types you presumably mean primitive types or built-in types. These include char, int, long, short, wchar_t, float, double and bool, amongst others. Most are simply variations of each other, but their lengths are implementation dependant. The only exception is char which is always 1 byte in length. User-defined types are those you yourself define or are defined for you. These include typedefs, enums, classes, structs and unions, but can also include some implementation-specific built-in types and all third-party types. Regardless, all user-defined types build upon the primitive data types or other user-defined types. In the case of class and struct types, methods (or member functions) can be associated with those types, thus combining data and the specific methods that act upon that data into a single entity. Objects are specific instances of a class or struct. A derived type is a class (or struct) which inherits from another class (or struct). A derivative cannot inherit from a primitive, enum or union. Derived types are also, by definition, user-defined types.
Is string is primitive or user defined data type?
String - is primitive data typestring - is user defined data type
What is the need for operator overloading?
1. Most fundamental data types have pre-defined operators associated with them. For example, the C++ data type int, together with the operators +, -, *, and /, provides an implementation of the mathematical concepts of an integer. To make a user-defined data type as natural as a fundamental data type, the user-defined data type must be associated with the appropriate set of operators. 2. Increases user readabitily.
What does the initials C.C. mean after a person who is a Free Mason?
User-defined (typedef) and compound types are possible. Heterogeneous aggregate data types
