not sure if i am doing this right but i need to make a validity check of a double that is between 1111111111 and 9999999999 and i was doing this for it:
the reason im asking for help is if i dont pass this class i get kicked out of college so help would be appreciatedCode:if(upc < 1111111111) {Console.WriteLine("error UPC is to small"); Invoice.UPC // so lost there dont know how to redo the class where it asks to input the UPC else ( upc > 9999999999) { Console.WriteLine("UPC is too big"); Invoice.UPC else if() Console.WriteLine"UPC is {0}",upc); } }im not very good at codeing but i want to learn
