hi,

why do we use : in flash mx 2004.

I went through the following example

function Product (id:Number, prodName:Name, price:Number)  
{  
this.id:Number = id;  
this.prodName:String = prodName;  
this.price:Number = price;  
}

Is it something like “C language”, where we declare char, int etc.,
