What is data structure in C++ with example?

A declaration specifies a unique name for the entity, along with information about its type and other characteristics . In C++ the point at which a name is declared is the point at which it becomes visible to the compiler.

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: struct type_name {

How to declare a structure in C++ programming? The struct keyword defines a structure type followed by an identifier (name of the structure). Then inside the curly braces, you can declare one or more members (declare variables inside curly braces) of that structure.

A “structure declaration” names a type and specifies a sequence of variable values (called “members” or “fields” of the structure) that can have different types . An optional identifier, called a “tag,” gives the name of the structure type and can be used in subsequent references to the structure type.
