c++ arrays c++11

可疑std:：array C++11库已损坏？我该怎么办？,c++,arrays,c++11,C++,Arrays,C++11,从谷歌我似乎找不到明确的答案，但我不知道该怎么办。我怀疑我用array C++11库为g++编写的一个更大的程序可能有问题，并编写了一个测试程序。我使用的是g++4.8.1 main.cpp： #include <iostream> #include <array> int main() { std::array<int,5> vector; return 0; } 有错误 In file included from main.cpp:2:

从谷歌我似乎找不到明确的答案，但我不知道该怎么办。我怀疑我用array C++11库为g++编写的一个更大的程序可能有问题，并编写了一个测试程序。我使用的是g++4.8.1

main.cpp：

#include <iostream>
#include <array>
int main()
{
    std::array<int,5> vector;

    return 0;
}

有错误

显然，从错误中可以看出，我包含了很多对std:：array文件的引用，这似乎是错误的根源。我该怎么办

提前谢谢

编辑：添加了编译命令和g++版本。

这是一个有效的C++11程序

您得到的错误很可能是由于方言选择：C++98模式不提供std:：array容器。请参阅

具体而言，您的错误可归结为以下几点：

main.cpp: In function 'int main()':
main.cpp:5:2: error: 'array' is not a member of 'std'
  std::array<int,5> vector;
  ^
main.cpp:5:13: error: expected primary-expression before 'int'
  std::array<int,5> vector;
             ^
main.cpp:5:13: error: expected ';' before 'int'

因此，只需将-std=c++11添加到命令行中，事情就可以正常进行。

无法使用以下命令复制：

错误消息与未提供选项-std=c++11一致

将该选项添加到命令行

之后，不知何故，一个输入错误进入了OP的命令行。应该是什么

template<typename _Tp, std::size_t _Nm>
  struct array
  {

变成

template<typename _Tp, std::size_t _Nm>
  struct Array
  {

在处理其余的.g/C++时，会导致一个BAZLLION编译器错误。把你的变量命名为C++类是不明智的。@保尔麦肯齐：他命名变量向量是完全有效的。他没有使用using声明将std:：vector引入范围。我不认为这是幸运的。是的，避免混淆标识符是很好的，但我认为这里的人们有点太挑剔了。@Cornstales:他没有看到这是无效的，他说这是不明智的，他是对的。void std:：Array:：swapint&’…嗯，这很奇怪。打开C:\MIW\LB\GC\\MIW32（4.C++），C++的C++数组，行到81行左右，是否是结构数组或结构数组？如果是问题，你会看到不同的错误：/Ur/Prime/C++/4.90/BIT/C++0xYAdvult.H:32：2:错误：错误：这个文件需要编译器和库支持ISO C++ 2011标准。此支持目前处于试验阶段，必须使用-std=c++11或-std=gnu++11编译器选项启用。
