Array vs. Structure: Know the Difference
By Shumaila Saeed || Published on February 28, 2024
An array is a collection of elements of the same type placed in contiguous memory locations, while a structure is a user-defined data type that groups different types of data.
Key Differences
An Array is a data structure consisting of a collection of elements, each identified by an array index. A Structure is a complex data type that allows the combination of data items of different kinds.

Arrays are used to store multiple values of the same type in a single variable, facilitating easy access and manipulation using indices. Structures, on the other hand, are used to represent a record, like a student's record, combining various data types, such as strings, integers, and floats.

In an Array, all elements must be of the same type, for example, an array of integers or an array of characters. In contrast, a Structure can store multiple data types; for instance, a structure can have an integer, a string, and a float simultaneously.

Arrays are particularly useful when dealing with a large number of data items that are of the same type, thereby offering efficient ways to organize and process data linearly. Structures provide a means of packing together different types of data elements, making it more suitable for modeling complex data.

Memory allocation in an Array is static and contiguous, meaning it's fixed at compile time, and elements are stored in consecutive memory locations. Structures have a more flexible memory allocation, allowing various types of data to be stored in non-contiguous memory locations.
