Data structures can be declared in C++ using the following syntax: struct type_name {member_type1 member_name1; member_type2 member_name2; member_type3 member_name3;..} object_names; Where type_name is a name for the structure type, object_name can be a set of valid identifiers for objects that have the

A data structure is a group of data elements grouped together under one name. These data elements, known as members , can have different types and different lengths. Data structures can be declared in C++ using the following syntax:

Data structures A data structure is a group of data elements grouped together under one name. These data elements, known as members, can have different types and different lengths. Data structures are declared in C++ using the following syntax: struct structure_name {member_type1 member_name1; member_type2 member_name2; member_type3 member_name3;..

Other data types Type aliases (typedef / using) A type alias is a different name by which a type can be identified. In C++, any valid type can be aliased so that it can be referred to with a different identifier. In C++, there are two syntaxes for creating such type aliases: The first, inherited from the C language, uses the typedef keyword:

In order to use a variable in C++, we must first declare it specifying which data type we want it to be. The syntax to declare a new variable is to write the specifier of the desired data type (like int, bool, float...) followed by a valid variable identifier.

In this case we have defined four data types: C, WORD, pChar and field as char, unsigned int, char* and char[50] respectively, that we could perfectly use in declarations later as any other valid type:

A class is an expanded concept of a data structure: instead of holding only data, it can hold both data and functions. An object is an instantiation of a class. In terms of variables, a class would be the type, and an object would be the variable.

Aug 13, 2017 · A concrete data type is the way an ADT is actually implemented. For example, a C++ compiler treats an int as a machine 32 (or larger) word, and uses the machine capabilities to perform mathematical operations on it.

Jan 3, 2022 · c++ has most of the classic data structures built into it, except for graphs (including nonbinary trees), and many of the algorithms. You will use those built in ones when coding after your studies of the container concepts.

C++ supports a wide variety of types based on the fundamental types discussed above; these other types are known as compound data types, and are one of the main strengths of the C++ language. We will also see them in more detail in future chapters.
