Write an overloaded function max that takes either two, three, or four parameters of type double and returns the largest of them.

You will use this main function to test your program.

int main$()$

$\{$

double result;

result $=$ max$(10\mathrm{.}0,20\mathrm{.}0)$;

cout $<<$ "Max$(10\mathrm{.}0,20\mathrm{.}0)="<<$ result $<<$ endl;

result $=$ max$(11\mathrm{.}5,21\mathrm{.}2,5\mathrm{.}3)$;

cout $<<$ "Max$(11\mathrm{.}5,21\mathrm{.}2,5\mathrm{.}3)="<<$ result $<<$ endl;

result $=$ max$(1\mathrm{.}8,2\mathrm{.}2,1\mathrm{.}7,2\mathrm{.}1)$;

cout $<<$ "Max$(1\mathrm{.}8,2\mathrm{.}2,1\mathrm{.}7,2\mathrm{.}1)="<<$ result $<<$ endl;

return $0$;

$\}$

Sample Output: Red colored texts are user inputs. Other texts are the output of the program.

Max$(10\mathrm{.}0,20\mathrm{.}0)=20$

Max$(11\mathrm{.}5,21\mathrm{.}2,5\mathrm{.}3)=21\mathrm{.}2$

Max$(1\mathrm{.}8,2\mathrm{.}2,1\mathrm{.}7,2\mathrm{.}1)=2\mathrm{.}2$
