The purpose of this lab is to practice the following:

Passing parameters by reference.

Write and run the following code. Write a short paragraph where you explain the output.

Be sure that your explanation includes the mechanics of pass$-$by$-$value and pass$-$by$-$

reference.

$-$void recolor$($int& red, int& green, int& blue$)\{$

$\frac{\frac{?}{?}}{?}$ reduce red value by $10\%$

$//$reduce green value by $15\%$

red red $***\mathrm{.}1$;

green $=$ green $-$ round green $**.15)$ ;

$\}$
