$6\mathrm{.}22\mathrm{.}1$: LAB: Swapping variables

Define a function named SwapValues that takes four integers as parameters and swaps the first with the second, and the third with the fourth values. Then write a main program that reads four integers from input and calls function SwapValues $0$ to swap the input values. The main program then prints the swapped values on a single line separated with spaces and ending with a newline.

The program must define and call the following function:

void SwapValues $($int& userVal$1,$ int& userVal$2,$ int& userVal$3,$ int& userVal$4)$

Ex: If the input is:

$3,8,2,4$

function SwapValues$()$ stores $8,3,4,$ and $2$ in userVal$1,$ userVal$2,$ userVal$3,$ and userVal$4,$ respectively. The main program then outputs:

$8$

Function SwapValues $0$ swaps the values referenced by the parameters and does not print any output.
