這是阿爾巴哈里（Albarhari）的例子public class Stack{int position;object[] data = new object[10]; // Why 10 nor 1? public void Push (object obj) { data[position++] = obj; } //do not understood; Why there is no looppublic object Pop() { return data[--position]; } //do not understood Why there is no loop}Stack stack = new Stack();stack.Push ("sausage");string s = (string) stack.Pop(); // Downcast, so explicit cast is neededConsole.WriteLine (s); // sausage我重寫了這里聽過的代碼public class Stack{    object[] data = new object[1];    public void Push(object obj) { data[0] = obj; }    public object Pop() { return data[0]; }}        Stack stack = new Stack();        stack.Push("abigale ff");        string s = (string)stack.Pop();         Console.WriteLine(s); // abigale ff為什么用10 in new object[10];而不是1或100 in為何在數(shù)據(jù)位置使用增量？我不了解數(shù)據(jù)位置的工作原理。{ data[position++] = obj; }以及 { return data[--position]; }它如何工作而沒有循環(huán)？我嘗試在彈出之前推送2個(gè)值，然后在彈出之前寫入它，但它僅顯示第二個(gè)值
