堆栈与队列算法-以数组来实现堆栈

以数组结构来实现堆栈的好处是设计的算法都相当简单。不过，如果堆栈本身的大小是变动的，而数组大小只能事先规划和声明好，那么数组规划太大了浪费空间，规划太小了则不够用，这是以数组来实现堆栈的缺点。

C++代码

用循环来控制元素压入堆栈或弹出堆栈，并仿真堆栈的各种操作，其中必须包括压入（push）与弹出（pop）函数，并在最后输出堆栈内的所有元素。 

#include<iostream>
using namespace std;

class Stack {
private:
	int MaxStack;
	int* data;
	int top;
public:
	Stack(int tempMaxStack) {
		this->MaxStack = tempMaxStack;
		data = new int[MaxStack];
		top = -1;
	}
	bool IsEmpty() {
		if (top == -1)
			return true;
		else
			return false;
	}

	void Push(int tempData) {
		if (top < MaxStack) {
			++top;
			data[top] = tempData;
		}
	}

	void Pop() {
		if (top != -1) {
			top--;
		}
	}

	int GetTop() {
		if (top != -1) {
			return data[top];
		}
	}
};

int main() {
	Stack* stack = new Stack(10);

	int value;
	cout << "请输入10个数据：" << endl;
	for (int i = 0; i < 10; i++) {
		cin >> value;
		stack->Push(value);
	}
	cout << "================" << endl;

	while (!stack->IsEmpty()) {
		cout << "从堆栈中弹出数据：" << stack->GetTop() << endl;
		stack->Pop();
	}
	cout << "================" << endl;

	delete stack;

	return 0;
}

扑克牌发牌算法

C++代码

以数组仿真扑克牌洗牌和发牌的过程。以随机数生成扑克牌后放入堆栈，放满52张牌后开始发牌，使用堆栈功能来给4个人发牌。 

#include<iostream>
#include<iomanip>
using namespace std;

class Card {
private:
	int card[52];
	int stack[52];
	string suit[4] = { "草花", "方块", "红桃", "黑桃" };
	int top;
public:
	Card() {
		for (int i = 0; i < 52; i++) {
			card[i] = i + 1;
			stack[i] = card[i];
		}
		top = -1;
	}

	bool IsEmpty() {
		if (top == -1)
			return true;
		else
			return false;
	}

	void Push(int tempData) {
		if (top < 52) {
			top++;
			stack[top] = tempData;
		}
	}

	void Pop() {
		if (top != -1) {
			top--;
		}
	}

	int GetTop() {
		if (top != -1) {
			return stack[top];
		}
	}

	void SwapCard() {
		srand((unsigned)time(NULL));
		for (int i = 0; i < 52; i++) {
			int j = rand() % 51 + 1;
			int temp = card[i];
			card[j] = card[i];
			card[i] = temp;
		}
		int i = 0;
		while (i != 52) {
			Push(card[i]);
			i++;
		}
	}

	void DealCard() {
		while (!IsEmpty()) {
			cout << "[" << suit[(GetTop() - 1) / 13] << setw(3) << GetTop() % 13 + 1 << "]\t";
			if (top % 4 == 0)
				cout << endl;
			Pop();
		}
	}
};

int main() {
	Card* card = new Card;
	cout << "洗牌中，请稍等：" << endl;
	card->SwapCard();
	cout << "发牌:" << endl;
	cout << "东家\t\t北家\t\t西家\t\t南家" << endl;
	cout << "======================================================" << endl;
	card->DealCard();

	return 0;
}
