Explain passing and returning objects, C/C++ Programming

Assignment Help:

Passing and Returning Objects

Objects can be passed to a function and returned back just like normal variables. When an object is passed by content, the compiler makes another object as a formal variable in the called function and copies all the data members from the actual variable to it. Objects can also be passed by address, which will be discussed later.

e.g.

                class check

                 {

                  public :

                check add(check);

                void get()

                                 {

                                   cin >> a;

                                 }

                                void put()

                                 {

                                   cout << a;

                                 }

                  private :

                                int a;

                 };

void main()

 {

  check c1,c2,c3;

  c1.get();

  c2.get();

  c3 = c1.add(c2);

  c3.put();

 }

check check :: add ( check c2)

 {

  check temp;

temp.a = a + c2.a;

return ( temp);

 }
