我的任务是添加一个异常处理程序，它指出“Error！ONLY INTEGER INPUT ALLOWED”。处理程序应该捕获双精度和字符串。我尝试过尝试和捕捉方法，但我不知道在哪里放置它以便它可以工作。我也读过关于catch all方法，这看起来像我需要做的。我刚刚完成了交换和比较的计数器方法，我相信它工作正常。

#include<iostream>
#include<conio.h>
using namespace std;

int main()
{
    int hold, swapNumber = 0, compare = 0, array[10];
    const string Error = "Error! ONLY INTEGER INPUT ALLOWED!";

    cout << "Enter 10 numbers: " << endl;
    try
    {
        for ( int i = 0; i < 10; i++ )
        {
            cin >> array[i];
            if ( !cin ) // Error in reading input stream
            {
                throw Error;
            }
        }
    }
    catch ( const string& E )
    {
        cout << E << endl;
        return 0;
    }
    cout << endl;

    cout << "Originally entered array by the user is: " << endl;
    for ( int k = 0; k < 10; k++ )
    {
        cout << array[k] << endl;
    }
    cout << endl;

    for ( int i = 0; i < 9; i++ )
    {
        for ( int k = 0; k < 9; k++ )
        {
            compare++;
            if ( array[k] > array[k + 1] )
            {
                hold = array[k];
                array[k] = array[k + 1];
                array[k + 1] = hold;
                swapNumber++;
            }
        }
    }

    cout << "Sorted Array is: " << endl;
    for ( int i = 0; i < 10; i++ )
    {
        cout << array[i] << endl;
    }
    cout << endl;

    cout << "Number of times Swapped: " << swapNumber << endl;
    cout << "Number of times Compared: " << compare << endl;

    getch();
}

如何在冒泡排序中为字符串和双精度实现异常处理程序？
