Download swapFunction.c, or copy it into your current directory on a CSE system by running

$ cp /web/cs1511/17s2/week05/files/swapFunction.c .

You have been given an incomplete main function, as well as a swap function to implement.

First, complete the void swap(int *a, int *b) function, which takes in pointers to two integers, and must swap their values around so that they are swapped once the function is complete.

Then, on line 17, call the swap function on the two variables, a and b, which have been read in. Do not change any other part of the main function.

Some Examples

Enter two numbers: 1 33
The numbers swapped are 33 and 1.

Enter two numbers: 17 -17
The numbers swapped are -17 and 17.

To run some simple automated tests:

$ 1511 autotest swapFunction

To run Styl-o-matic:

$ 1511 stylomatic swapFunction.c
Looks good!
