function with n number of arguments
rarely we could need of such function but
i m sure whilst programming, programmers have used such functions of
their framework functions/base library functions e.g, in case of c
language you must have used printf() function (if u didn’t use it i can
say u r n’t c programmer :D) it takes n number of arguments, hmm still
confuse ok let me tell u how ………..
printf(”sum of %d and %d is %d”,1,2,1+2) ; i hope now you got my point.
but what if you have to make function with n number of arguments using .net (c#.net) then don’t worry main hoon na 
simply u would need to know/utilize PARAMS keyword of c# let me give u any example
private object Sum(params object[] numbers)
{
int sum = 0;
foreach (object o in numbers)
if (o.GetType() == typeof(int))
sum += (int)o;
return (object)sum;
}
i used object to make it more flexible for you.
