c++函数模板二栈实现

1 没有使用模板的栈实现

 1 #include <iostream>
 2 #include <string>
 3 using namespace std;
 4
 5
 6 class Stack
 7 {
 8 public:
 9     Stack(int size = 1024);
10     ~Stack();
11     bool isEmpty();
12     bool isFull();
13     void push(int data);
14     int pop();
15 private:
16     int* space;
17     int top;
18
19 };
20
21 Stack::Stack(int size)
22 {
23     space = new int(size);
24     top = 0;
25 }
26 Stack::~Stack()
27 {
28     delete[]space;
29 }
30 bool Stack::isEmpty()
31 {
32     return top == 0;
33 }
34 bool Stack::isFull()
35 {
36     return top == 1024;
37 }
38 void Stack::push(int data)
39 {
40     space[top++] = data;
41 }
42 int Stack::pop()
43 {
44     return space[--top];
45 }
46
47 int main()
48 {
49     Stack s(100);
50     int i = 0;
51     /*if (!s.isFull())
52     {
53         s.push(10);
54     }*/
55     while (!s.isFull()&&i<1024)
56     {
57         s.push(i);
58         i+=10;
59     }
60     i = 0;
61     while (!s.isEmpty()&&i<1024)
62     {
63         cout << s.pop() << endl;
64         i += 10;
65     }
66     cin.get();
67     return 1;
68 }

2 使用模板以后的栈实现

 1 #include <iostream>
 2 #include <string>
 3 using namespace std;
 4
 5 template<typename T>
 6 class Stack
 7 {
 8 public:
 9     Stack(int size)
10     {
11         space = new T[size];
12         top = 0;
13     }
14     ~Stack();
15     bool isEmpty();
16     bool isFull();
17     void push(T data);
18     T pop();
19 private:
20     T* space;
21     int top;
22
23 };
24
25 template<typename T>
26 Stack<T>::~Stack()
27 {
28     delete[]space;
29 }
30 template<typename T>
31 bool Stack<T>::isEmpty()
32 {
33     return top == 0;
34 }
35 template<typename T>
36 bool Stack<T>::isFull()
37 {
38     return top == 1024;
39 }
40 template<typename T>
41 void Stack<T>::push(T data)
42 {
43     space[top++] = data;
44 }
45 template<typename T>
46 T Stack<T>::pop()
47 {
48     return space[--top];
49 }
50
51 int main()
52 {
53     Stack<double> s(100);
54     if (!s.isFull())
55         s.push(10.4);
56     if (!s.isFull())
57         s.push(10.5);
58     if (!s.isFull())
59         s.push(10.6);
60     if (!s.isFull())
61         s.push(10.7);
62     if (!s.isFull())
63         s.push(10.8);
64     if (!s.isFull())
65         s.push(10.9);
66
67     Stack<string> s1(100);
68     if (!s1.isFull())
69         s1.push("ni");
70     if (!s1.isFull())
71         s1.push("hao");
72
73     while (!s1.isEmpty())
74     {
75         cout << s1.pop() << endl;
76
77     }
78     cin.get();
79     return 1;
80 }

可以其他类型可以自己多敲敲哦
