崩溃的时候在弹出的对话框按相应按钮进入调试，按Alt+7键查看Call Stack即“调用堆栈”里面从上到下列出的对应从里层到外层的函数调用历史。双击某一行可将光标定位到此次调用的源代码或汇编指令处，看不懂时双击下一行，直到能看懂为止。

这是数组访问越界。 你可以先确定奔溃，大体位置，然后一个个调试。

#include<iostream>

using namespace std;

const int MaxSize =5;
int Fill_array(double*, int);
void Show_array(const double*, int);
void Reverse_array(double*, int);

int main()
{
    double array[MaxSize];
    int n = Fill_array(array, MaxSize);
    cout << n << " elements wan entered!" << endl;
    Show_array(array, n);

    Reverse_array(array, n);
    Show_array(array,n);

    if (n <= 2)
        cout << "The element is less than 3,we can not reverse it without the first and the last one." << endl;
    else
    {
        Reverse_array(array + 1, n - 2);
        Show_array(array, n);
    }

    //system("pause");
    return 0;
}


int Fill_array(double*array, int num)
{
    int i;
    cout << "Please enter numbers(q to quit): ";
    for (i = 0; i < num; ++i)
    {
        if (!(cin >> array[i]))
            break;
    }
    //array[i] = '\0';   /*这是做什么？array是double，不是char* 类型*/
    return i;
}


void Show_array(const double *array, int num)
{
    for (int i = 0; i < num; ++i)
        cout << array[i] << " ";
    cout << endl;
}


void Reverse_array(double *array, int num)
{
    double temp;
    for (int i = 0, j = num-1; i<j; ++i, j--)
    {
        temp = array[i];
        array[i] = array[j];
        array[j] = temp;
    }
}

哪儿有内存溢出的，没发现； 正常运行； 有一处,array是double类型，不是char*类型，所以没必要将'\0'赋值给array[i]
