How do i check which is the largest element in a function which takes default parameters?

Create a function called max that returns the maximum of the parameters it takes. It can
take as parameters only positive integers. The function can take 1 , 2  ,3  or 4 parameters. DO
NOT USE FUNCTION OVERLOADING. (hint use default parameters)  Test your function in
main for 2 3  and 4 parameters. Read the parameters from the user. Below we show the
example input output :

Answer 1

Set the default parameters as small as possible that is the minimum value that data type can hold.
