$1.$ Write a C$++$ program that does the following:

a$.$ Create a C$++$ file with the name problem$4.$cpp$.$

b$.$ Write the function areVeryDifferent$$which determines whether the two integer parameters are very different if they differ by more than $10.$

c$.$ Type in the following main function into your C$++$ program file:

int main$()$

$\{$

$$int x $=4,$ y $=10,$ z $=-4$;

$$if $($areVeryDifferent$($x$,$ y$))$

$$cout $<<"$x and y are very different." $<<$ endl;

$$if $($areVeryDifferent$($x$,$ z$))$

$$cout $<<"$x and z are very different." $<<$ endl;

$$if $($areVeryDifferent$($y$,$ z$))$

$$cout $<<"$y and z are very different." $<<$ endl;

$$

$$return $0$;

$\}$

d$.$ The output from this program is:

y and z are very different.
