嘿傢伙我正在做某種事情，並且正在嘗試實施冒泡排序，合併排序和shell排序。我用一個過時的技術，但我想知道，如果你們可以讓我知道爲什麼我不斷收到以下錯誤：在sortApplication2.exe在0x01135EF7FirstChance異常StackOverFlow合併排序外殼排序泡沫排序
第一次機會異常：0xC00000FD：堆棧溢出（參數：00000000，0x00542000） 。sortApplication2.exe中的0x01135EF7未處理的異常：0xC00000FD：堆棧溢出（參數：0x00000000，0x00542000）。
我正在使用Visual Studio 2012，如果它扮演任何角色。我的代碼有三個不同的文件，所以我會分別發佈。
我的頭文件：
#pragma once
class sort
{
public:
sort();
void random1(int array[]);
void random2(int array[]);
void random3(int array[]);
void bubbleSort(int array[], int length);
/*void merge(int *input, int p, int r);
void merge_sort(int *input, int p, int r);*/
void shellSort(int array[], int length);
};

我知道這是一個很大的代碼。而且我可能有很多方法可以使代碼更好。 我只想知道是什麼導致上面的錯誤，因爲我找不到我的編譯器。
嘗試將代碼縮小到仍顯示問題的*最短*樣本。 –
堆棧跟蹤在這裏也會有所幫助... –
