C Structure with examples. C Structure is a collection of different data types which are grouped together and each element in a C structure is called member. If you want to access structure members in C, structure variable should be declared. Many structure variables can be declared for same structure and memory will be allocated for each separately. It is a best practice to initialize a structure to null while declaring, if we don’t assign any values to structure members. Difference between C variable, C array and C structure: A normal C variable can hold only one data of one data type at a time. Data structures Data structures A data structure is a group of data elements grouped together under one name. An array can hold group of data of same data type. A structure can hold group of data of different data types and. We can also store and access these data for many students using array of structures.

C Structures can be used in drawing and floppy formatting. C Structures can be used to clear output screen contents. C Structures can be used to check computer’s memory size etc. Structures provide a way of storing many different values in variables of potentially different types under the same name.
