CodeBlocks HelloWorld C示例不起作用：错误“ptrdiff_t”尚未声明

标签： c++ codeblocks

我总是使用MinGW或Dev-C ++在Microsoft Windows上用C ++编写代码，但现在我必须使用代码块。 我已经下载并使用标准程序安装它。

我试图运行超简单的HelloWorld.cpp示例文件，但是我收到了很多编译错误：

#include <iostream>
using namespace std;

int main()
{
  cout << “Hello World!” << endl;
}

这是我的编译器错误列表：

似乎在标准库中缺少某些结构（ptr_diff_t，size_t等）。

有人可以帮助我，让我编译我的简单HelloWorld.cpp吗？

谢谢！

答案 0 :(得分：0)

这是引起问题的引号：

了解“”与""的不同之处？这就是它没有编译的原因。它们不是C ++中的有效字符。

答案 1 :(得分：0)

您使用了错误的引号。将“和”更改为""
