Return Custom Data Types
In C++, you can return custom structures and classes from functions. When you return an instance of a struct or class from a function, you essentially return a copy of the object ( the same as returning simple data types).
This allows you to encapsulate related data and behavior within a single structure or class instance, pass it around between functions, or use it in different parts of your program.
To return a structure/class, you must use the structure/class name as a type specifier in the function signature.
main.cpp
Code Description
This C++ code demonstrates the usage of custom structures and functions to create and return instances of a custom structure named
Person
. Here's the breakdown of the code:Person
Struct:string name
and int age
.- Description: Defines a structure named
Person
with attributes name
to store the person's name and age
to store the person's age.createPerson()
Function:Person
(returns a Person
object).- Description: This function creates a new
Person
object, initializes its name
and age
attributes, and then returns the copy of the created object.main()
Function:main()
function, the createPerson()
function is utilized to create a Person
object named person1
. The object is initialized with specific values and then accessed for its name
and age
attributes. The results are then printed to the console using cout
, showcasing the content of the created custom structure.
