write C$++$ codes to create a function of void type named "findQuadratic$()"$ which will take two int parameters, x and y$,$ and perform a calculation based on the equation: f$($x$,$ y$)=2$x $+$ xy $+3$y$.$ Then test the "findQuadratic$()"$ function from the "main$()"$ function using the following values of x and y$.$

x y

$--------$

$-37$

$5-4$

$-2-4$

$711$

Use $"\backslash$t$"$ insert "tab" between every two adjacent values. Make sure the output look similar to the following.

x y f$($x$,$y$)$

$-37-6$

$5-4-22$

$-2-4-8$

$711124$
