Create a $C++$ program called lab$1\_1.$cpp that reads three numbers from a user. Then it calls a function named find$\_$max$(),$ which takes three integers are arguments, finds the largest of the three numbers, and then returns the largest number. This result is finally printed onto the screen.

Here is your function prototype:

int find$\_$max$($int $x,$ int $y,$ int $z$;

Here is your main function $($note you must use this main, you aren't allowed to modify it$)$:

int main$()$

$\{$

int num$1,$ num$2,$ num$3,$ largest;

cout $$ "Please enter three numbers: $"$;

cin $$ num$1$ num$2$ num $3$ ;

$//$write the statement that calls find$\_$max$()$ and stores

$\frac{\frac{?}{?}}{?}$ the value returned in largest

cout $$ "The largest number is $"$ largest $".$ In$"$;

return $$;
