棧是一種線性的邏輯結構，可依賴陣列和連結串列這兩種物理結構實現。

棧包含入棧、出棧的操作，是一種FILO的結構。using System;

namespace Test01

{

public class MyStack

{

public int size = 0;

int[] stack;

public MyStack(int capacity)

{

stack = new int[capacity];

}

public int Pop()

{

if (size <= 0)

{

Console.WriteLine("棧為空");

return -1;

}

int value = stack[size - 1];

return value;

}

public bool Push(int value)

{

if (size > stack.Length)

{

Console.WriteLine("棧已滿");

return false;

}

stack[size] = value;

size++;

return true;

}

public void Println()

{

for (int i = 0; i < size; i++)

{

Console.WriteLine(stack[i]);

}

}

}

class Program

{

static void Main(string[] args)

{

MyStack myStack = new MyStack(10);

myStack.Push(111);

int value = myStack.Pop();

myStack.Println();

}

}
