How to Complete a Swap() Function while Using Other Functions from Other Files (C++)

Question

Complete the Swap() function in main.cpp to exchange the values of the num field of two Number objects, num1 and num2. Since both num1 and num2 are changed inside Swap(), reference operators (&) are used to pass num1 and num 2 by reference.

Hint: Refer to the given Number class to see the definitions of num field and other functions available.

Ex: If num1 is 19 and num2 is 178, calling Swap(num1, num2) will swap the values so that num1 becomes 178 and num2 becomes 19.

Swap(num1,num2);

cout << "num1 = " <<num1.GetNum()

return 0;
