Structures and Functions in c++

Structures and Functions in c++

n this article, you'll find relevant examples to pass structures as an argument to a function, and use them in your program.

Structure variables can be passed to a function and returned in a similar way as normal arguments.

Passing structure to function in C++

A structure variable can be passed to a function in similar way as normal argument. Consider this example:

Example 1: C++ Structure and Function

1. #include <iostream>
2. using namespace std;
4. struct Person
5. {
6. char name[50];
7. int age;
8. float salary;
9. };
11. void displayData(Person); // Function declaration
13. int main()
14. {
15. Person p;
17. cout << "Enter Full name: ";
18. cin.get(p.name, 50);
19. cout << "Enter age: ";
20. cin >> p.age;
21. cout << "Enter salary: ";
22. cin >> p.salary;
24. // Function call with structure variable as an argument
25. displayData(p);
27. return 0;
28. }
30. void displayData(Person p)
31. {
32. cout << "\nDisplaying Information." << endl;
33. cout << "Name: " << p.name << endl;
34. cout <<"Age: " << p.age << endl;
35. cout << "Salary: " << p.salary;
36. }

Output

Enter Full name: Bill Jobs
Enter age: 55
Enter salary: 34233.4

Displaying Information.
Name: Bill Jobs
Age: 55
Salary: 34233.4
