有人可以通過異常處理指向正確的方式來執行此程序嗎?這是一個堆棧程序。在C++中拋出關鍵字
1)#include<iostream>
2)#include<stdlib.h>
3)#include<string.h>
4)using namespace std;
5)
6)template<class T>
7)class Stack {
8)private:
9) int max;
10) int top;
12) T* items;
13)public:
14) Stack(int size) {
15) max = size;
16) top = -1;
17) items = new T[max];
18) }
19) ~Stack(){delete [] items;}
20)
21) void push(T data) throws Exception{
22) if(full()) {
23) throw new StackException("Out of space!");
24) }
25) items[++top] = data;
26) }
27) T pop(){
28) if(empty()) throws Exception {
29) throw new StackException("No more elements to delete");
30) }
31) return items[top--];
32) }
33)
34) bool full() { return top == max-1; }
35) bool empty() { return top == -1; }
36)};
37)
38)int main() {
39) try{
40) Stack<int> s(10);
41) s.push(1);
42) s.push(2);
43) cout<<s.pop()<<endl;
44) }
45) catch(StackException e){
46) cout<<e.what()<<endl;
47) }
48) return 0;

編輯:我收到以下錯誤。我是新來的異常在C++處理,想知道我在做正確的 -

任何提示什麼是錯的?你面臨什麼問題?你有什麼嘗試? –
「這是我的代碼,修復它」。好吧:不。你對異常有任何疑問嗎? btw:你在混合使用C和C++頭文件嗎? – Zeta
