In the C programming language, struct is the keyword used to define a composite, a.k.a. record, data type – a named set of values that occupy a block of memory. It allows for the different values to be accessed via a single identifier , often a pointer .
C also provides a special type of member known as a bit field, which is an integer with an explicitly specified number of bits. A bit field is declared as a structure (or union) member of type int, signed int, unsigned int, or _Bool, [note 4] following the member name by a colon (:) and the number of bits it should occupy. The total number of ...
The C language provides the record concept using structs. Most languages designed after Pascal (such as Ada , Modula , and Java ), also supported records. Although records are not often used in their original context anymore (i.e. being used solely for the purpose of containing data), records influenced newer object-oriented programming ...
Structures may be initialized or assigned to using compound literals. A function may directly return a structure, although this is often not efficient at run-time. Since C99, a structure may also end with a flexible array member. A structure containing a pointer to a structure of its own type is commonly used to build linked data structures:
It is sometimes called a structure or by a language-specific keyword used to define one such as struct. It falls into the aggregate type classification which includes homogenous collections such as the array and list .
typedef is a reserved keyword in the programming languages C, C++, and Objective-C.It is used to create an additional name (alias) for another data type, but does not create a new type, [1] except in the obscure case of a qualified typedef of an array type where the typedef qualifiers are transferred to the array element type.

Incomplete Potty Training. At the age of 3 months, puppies are still considered the equivalent of infants. Consider that their small bodies and minds are in the process of developing.
C struct data types may end with a flexible array member [1] with no specified size: struct vectord { short len ; // there must be at least one other data member double arr []; // the flexible array member must be last // The compiler may reserve extra padding space here, like it can between struct members };
