In a real-world application, we need to group different types of logically related data. For example: If we want to create a record of students that consists of name, roll no, and marks. Then to store such records we use structure. The structure is a collection of heterogeneous data types which are grouped together under a single name. A structure can contain any valid data types like int, char, float, or even arrays and other structures. Each variable in structure is called structure member. To define a structure, we use the 'struct' keyword.
