Info

STRUCT, TYPEDEF, ENUM & UNIONStructure (struct)• With array, we can only declare one data type per array.• For different data type, we need another arraydeclaration.• It is single type aggregate data type.• Struct overcomes this problem by declaring compositedata types which can consist different types.• A structure is a collection of related data items stored inone place and can be referenced by more than onenames.• These data items are different basic data types. So, thenumber of bytes required to store them may also vary.• A structure type is a user-defined composite type.• It is composed of fields or members which can bedifferent types.www.tenouk.com, © 2/93
STRUCT, TYPEDEF, ENUM & UNION• In C++, a struct is same as a class except that itsmembers are public by default.• In order to use a structure, we must first declare a structuretemplate.• The variables in a structure are called elements or members.• In C, you must explicitly use the struct keyword to declare astructure however in C++, this is unnecessary, once the typehas been defined.• In C99, the allowable data types for a bit field include qualifiedand unqualified _Bool, signed int, and unsigned int.• The default integer type for a bit field is signed.• You have the option of declaring variables when the structuretype is defined by placing one or more comma-separatedvariable names between the closing brace and the semicolon.www.tenouk.com, © 3/93
