CodeBlocks HelloWorld C示例不工作：未聲明錯誤「ptrdiff_t」

我一直使用MinGW或Dev-C++在Microsoft Windows上使用C++編寫代碼，但現在必須使用代碼塊。我已經下載並使用標準程序進行安裝。CodeBlocks HelloWorld C示例不工作：未聲明錯誤「ptrdiff_t」

我試圖運行supersimple HelloWorld.cpp示例文件，但我得到了很多編譯錯誤：

#include <iostream> 
using namespace std; 

int main() 
{ 
    cout << 「Hello World!」 << endl; 
}

這裏是我的編譯器錯誤的列表：

看來，在標準庫中，某些結構不存在（ptr_diff_t,size_t等）。

有人可以幫我，讓我編譯我簡單的HelloWorld.cpp？

謝謝！

必要的包括你的程序是''和''。 –

@Kerrek SB，請參閱http://www.cplusplus.com/reference/iostream/;我相信你通常不需要將istream或ostream直接包含在內，因爲它們都被iostream覆蓋。我不知道問題出在哪裏，因爲Eclipse和MinGW可以很好地工作。我猜這是一個配置問題。你能得到用於編譯的命令行，並從命令提示符嘗試它嗎？ – cosimo193

@ cosimo193：該網站是可憎的。不過，我認爲你（不知不覺）正確地認爲C++ 11 *要求''包含''; C++ 03沒有這樣說。 –

這是這是導致該問題的引號：

瞭解如何「」是""不同？這就是它沒有編譯的原因。它們在C++中不是有效的字符。

您正在使用錯誤的引號..更改「和」到""
