A programmer selects an appropriate data structure and uses it according to their convenience. Structure within structure (or) nesting of structure is used to create complex records. A structure can not derive/inherit from any structure or class. In line 15, the prototype of function print_struct() is declared which accepts an argument of type array of structures.. How it works: In lines 7-13, a structure company is declared with four members namely name, ceo, revenue, pps.. This is also known as nesting of structure. The declaration is same as the declaration of data type in structure. Unions provide an efficient way of using the same memory location for multiple-purpose. You can define a union with many members, but only one member can contain a value at any given time. We use struct keyword to declare a structure. Creating Structure variable and Union variable to access their respective members is the same with keyword difference. The C Programming language has many data structures like an array, stack, queue, linked list, tree, etc. In this tutorial, we will learn about structures in C its need, how to declare, define and access structures. 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 Structure type variable can store more than … C provides you with an additional and simpler approach where you can use a special data structure, i.e., structure, in which, you can group all the information of different data type regarding an entity. Structure is a user defined data type. Data structures Data structures A data structure is a group of data elements grouped together under one name. All the structure elements are stored at contiguous memory locations. In C, a structure declaration can be placed inside another structure.
