Question

使用g++ file.cpp -std=c++11

在Windows上编译以下程序

#include<bits/stdc++.h>
using namespace std;

int main() {
    int x = 0;
    cout << x;
    return 0;
}

给出了一个错误，您可以在下面的链接中看到（由于stackoverflow的与文本约束相比代码太多而无法在此处发布错误，抱歉以这种方式发布！）

任何指针哪里出错了？（使用gcc 5.3）

Answer 1

使用std = gnu ++ 11

g++ file.cpp -std=gnu++11

无法用g ++编译头位/ stdc ++ 11
