passing objects as function parameters
 

hhey sir i need some information about his topic urgently

Re: passing objects as function parameters
 

what do you want to know about it? c++ objects are normally passed by reference to avoid expensive duplication and to let other functions use the same object as the calling function.

class MyClass

{

  // blabla

};



void foo(MyClass& obj)

{

    // class passed by reference

}



int main()

{

    MyClass myclass; // create an instance of the class

    foo(myclass); // pass it to another function

}

Re: passing objects as function parameters
 

They can also be passed as pointers, if you want to use them. Thought I believe it's considered better to use references over pointers when possible.

class MyClass

{

  // blabla

};



void foo(MyClass* obj)

{

    // class passed by reference

}



int main()

{

    MyClass myclass; // create an instance of the class

    foo(&myclass); // pass it to another function



    //or....

   MyClass* myclass = new MyClass;//create a pointer to the class and allocate an object at its location

   foo(myclass);//call the function

   delete myclass;//deallocate the object

}
