指针、动态数组和内存泄漏

我的完整代码链接在底部。

我遇到的第一个问题是,在第一次需要增加大小后,动态分配的数组变得混乱。相关代码如下。

    while (counter <= arraySize)
    {
        cout <<"Please enter an integer number. Use 999999 (six 9's) to stop\n";
        if (counter == arraySize)           //If the counter is equal to the size of the array
        {                                   //the array must be resized
            arraySize +=2;
            int *temp = new int[arraySize];
            for (counter = 0; counter < arraySize; counter++)
            {
                temp[counter] = arrayPtr[counter];
            }
            delete [] arrayPtr;
            arrayPtr = temp;
            counter ++;                     //the counter has to be reset to it's original position
        }                                   //which should be +1 of the end of the old array
        cin >> arrayPtr[counter];
        if (arrayPtr[counter] == sentinel)
        {
            cout << "Sentinel Value given, data entry ending.\n";
            break;
        }
        counter ++;
    }

这会产生一个意外的操作,它不等待哨兵值,而是开始列出内存中超过该点的整数(因为没有边界检查)。

下一个问题是我的排序函数拒绝运行。我试着在5个值上进行测试,程序在到达代码的特定部分时崩溃。

sorting (arrayPtr);

但函数本身看起来是这样的:

void sorting (int *arr)
{
    int count = 0, countTwo = 0, tempVal;

    for (count = 0; arr[count] != 999999; count++)          //I figured arr[count] != 999999 is easier and looks better
    {                                                       //A bunch of if statements
        for (countTwo = 0; arr[countTwo] != 99999; countTwo++)
        {
            if (arr[countTwo] > arr[countTwo+1])
            {
                tempVal = arr[countTwo];
                arr[countTwo] = arr[countTwo+1];
                arr[countTwo+1] = tempVal;
            }
        }
    }   
}

在此问题上的任何帮助都将不胜感激。
