Hi,
The var-arg is infact an array, So when we can pass the array object to the method and iterate through its elements , Why do we need var-arg and we need to rememeber the additional syntax that comes along with it.
I am just wondering why var-arg is required?
Thanks
Deepak

Well imagine a situation where you dont know the number of arguments that you are going to pass to a function. In such cases you could just call the function with var args like so...

func(1,2,3,4) or func(1,2)
