c# - Array value in a set of value ranges isn't displaying -


i'm trying make simple program display discount depending on how many items customer purchases.

using system; using system.collections.generic; using system.linq; using system.text;  namespace consoleapplication11 {     class program     {         const int size = 4;         static void main(string[] args)         {             int itemsbought = 0;             double discountitem = 0;             int[] items = new int[size] { 0, 10, 26, 61 };             double[] discount = new double[size] { 0.0, 0.05, 0.10, 0.15 };              inputitems(ref itemsbought);             getdiscount(items, discount, ref itemsbought, ref discountitem);              console.writeline("your discount {0}", discountitem);          }          private static void getdiscount(int[] items, double[] discount, ref int itemsbought, ref double discountitem)         {             int idx = 0;             (idx = 1; idx >= items.length; idx++)             {                 while (itemsbought >= items[idx])                 {                     discountitem = discount[idx];                     idx++;                 }             }         }         private static void inputitems(ref int itemsbought)         {             console.writeline("enter amount of items bought");             while (!int.tryparse(console.readline(), out itemsbought))                 console.writeline("error, whole numbers only");         }     } } 

somehow know logic of bad not sure. topic 1 being of course discount aligns input displaying. it's displaying "the discount 0" no matter value inputed.

your for loop wrong. first, isn't executing because condition idx >= items.length;. should opposite: idx < items.length;. second, i'm not sure why setting idx 1 in initializer...

the inner while loop doesn't want to, i'm not sure want in first place.
