In Java, we were unable to write methods to swap the values of two variables because everything in Java is pass$-$by$-$value: local variables inside of the method are copies of the variables that were passed in$.$ In C$++,$ however, we can take advantage of pass$-$by$-$reference to finally implement a swap function!

Task: Edit Swap.cpp

In this part of the assignment, we have provided a file called Swap.cpp that is currently essentially blank. In this part of the assignment, you will fill in the code in order to write a global function called swap that swaps the values of two int arguments. Be sure to only modify Swap.cpp: do not modify Swap.h$.$
