有分段故障C++

我知道我不是最好的，但我試圖學習。我嘗試編譯我的程序，它工作。我運行該程序，但是當我到達最後時，它說轉儲出現分段錯誤。我認爲這涉及到我想要做的排序。它在我嘗試通過竊取頁面進行排序之前就起作用了。在我做到這一點後，交換停止工作。任何想法爲什麼？有分段故障C++

它崩潰，因爲它有可怕的格式。只是在開玩笑。認真地：正確地格式化您的代碼：P – user463035818

爲什麼不讓您的'播放器'和'選擇'陣列？你重複5次相同的代碼。 – PaulMcKenzie

林不知道爲什麼。我是新來的，並不完全確定我在做什麼。它工作正常，直到我試圖理清我的txt文件。它打印並正在工作。我正在嘗試這樣做，類似於我在課堂上必須做的一個項目，但是我自己去做了。我知道它可能不是最漂亮的，但在這一點上，如果我能讓它工作，我會對此感到滿意。 – DaBears5423

我不知道它是唯一的問題，但它是一個（大！）的問題。

您分配了5 Player空間

Player* PlaArray = new Player[5];

，但您嘗試使用他們的10

if (pick5 == "5"); 
{ 
    for(int x = 0; x<10; x++) 
    { 
     inFile.open("C.txt"); 
     getline(inFile, position, ','); 
     getline(inFile, firstname, ','); 
     getline(inFile, lastname, ','); 
     getline(inFile, team, ','); 
     getline(inFile, pointsPG, ','); 
     getline(inFile, reboundsPG, ','); 
     getline(inFile, assistsPG, ','); 
     getline(inFile, stealsPG, '\n'); 
     PlaArray[x].setFirstname(firstname); 
     PlaArray[x].setLastname(lastname); 
     PlaArray[x].setPosition(position);

這是不好的。

p.s .:和是的：tobi303是對的：你有一個可怕的格式。我們在開玩笑，但建議這是一個很好的建議：正確格式化您的代碼。

p.p.s：抱歉我的英文不好。

謝謝你擺脫了錯誤！我應該做些什麼來改善格式？它也不會交換？任何想法如何解決這個問題？ – DaBears5423

+0

爲了更好的格式，您應該使用支持自動縮進的文本編輯器。我使用'vim'，但也有其他的。對於交換，刪除你的函數並使用標準交換（如果你使用C++ 98或者#include ，添加'#include '，如果你使用C++ 11或C++ 14 ） – max66
