There are no common types of user-defined exceptions. If they were common, they'd already be provided as standard. The whole point of a user-defined exception is to differentiate between the common and the uncommon. For common exceptions such as range errors we can simply throw a std::range_error; we don't need a user-defined exception unless we need to throw additional information that cannot easily be provided by the standard library exception.
They are user-defined. In other words: You & Me (Users) define them (make them). There is an endless number of user-defined exceptions
user defined exception is created by user such as arthmetic,number format exception ...
The two types of convertion areImplicitExplicit
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.
throw is the keyword used to invoke the exception.throw new NoBalanceException("No balance please");

A user-defined object is an instance of a user-defined type, typically a class, or an enum.
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.
Integer types, floating point types, Boolean types, character types, string types, pointer and array types, reference types, enumeration and other user-defined types.
User-defined (typedef) and compound types are possible. Heterogeneous aggregate data types
No. There are no built-in functions in C, there are only built-in types and built-in operators for those types. All functions are user-defined, including those defined by the C standard library. There are no user-defined operators in C, but you can implement operators as named functions if required. A header file (*.h file) typically contains a group of related user-defined function and/or user-defined type declarations which can be included in any source file that requires them. Every user-defined function or user-defined type name used by a program must have one (and only one) definition, usually contained in a corresponding source file (*.c file) or library file (*.lib file). Built-in types and their corresponding operators do not require a header file since they are part of the language itself (hence they are built-in).
