$//$ This program takes two numbers $($payRate & hours$)$

$//$ and multiplies them to get grosspay.

$//$ It then calculates net pay by subtracting $15$

Exercise $3$: Are the parameters gross and net, in the modified calPaycheck func$-$ tion you created in Exercise $1$ above, pass by value or pass by reference?

Exercise $4$: Alter the program so that gross and net are printed in the function compute computePaycheck instead of in main$().$ The main$()$ function executes the statement

cout $<<"$We hoped you enjoyed this program" $<<$ endl; after the return from the function calPaycheck.

Exercise $5$: Run the program again using the data from Exercise $2.$ You should get the same results. All parameters should now be passed by value.
