If a C++ program contains code to declare both num1 and num2 as integers with a value of O and then accept any two numbers from the user from the keyboard (to replace the values currently in num1 and num2). Write the code to swap the values in num1 and num2. The value in num1 ends up in num2 and the value of num2 ends up in num1. Note - you will likely need to declare an additional variable. (5 points)
