What is definition struct?

In programming, a struct or structure is a collection of variables that are grouped together under a single name, which can be used to store a logically-related set of data. A struct allows the programmer to define a custom data type that combines different types of variables, such as integers, floats, or even other structs. Structs are especially useful for organizing data in object-oriented programming languages, such as C++, Java, and Python. They provide a way to encapsulate data and functionality within a single object, which can make complex code easier to read and maintain. A struct definition typically includes the data types and names of the variables that will be contained within the struct, and may also include methods or functions that can be used to manipulate the struct's data.
