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

C++ Program to Store and Display Information Using Structure By Simple Method This program stores the information (name, fname id and course ). In this program, a structure,  student  is created. This structure has three members:  name  (char),  fname  (char) and  id  (int ) and course (char ). #include<iostream> using namespace std; // declaring the strct struct Student{ int id; char name[10]; char fname[10]; char course[10]; }; int mian() { //create the struct type object Student s1; //get student info cout<<"Enter Your Name "<<endl; cin>>s1.name; cout<<"Enter Your Id "<<endl; cin>>s1.id; cout<<"Enter Your Father Name "<<endl; cin>>s1.fname; cout<<"Enter Your Course Title"<<endl; cin>>s1.course; //display student info cout<<"Your Name is"<<s1.name; cout<<"Your Id is"<<s1.id; cout...

C++ Program to Add Complex Numbers by Passing Structure to a Function

Add Complex Numbers by Passing Structure to a Function This program takes two complex numbers as structures and adds them with the use of functions. Example: Source Code to Add Two Complex Numbers // Complex numbers are entered by the user #include <iostream> using namespace std ; typedef struct complex { float real ; float imag ; } complexNumber ; complexNumber addComplexNumbers ( complex , complex ); int main () { complexNumber n1 , n2 , temporaryNumber ; char signOfImag ; cout << "For 1st complex number," << endl ; cout << "Enter real and imaginary parts respectively:" << endl ; cin >> n1 . real >> n1 . imag ; cout << endl << "For 2nd complex number," << endl ; cout << "Enter real and imaginary parts respectively:" << endl ; cin >> n2 . real >> n2 . imag ; ...
