这在C++ 11下是合法的吗？

string s = R"(This is the first line
And this is the second line)";

......相当于:

string s = "This is the first line\nAnd this is the second line";

我很好奇,如果两个线程同时请求分配内存,是否存在内存分配锁定.我正在使用OpenMP来执行多线程,C++代码.

操作系统:主要是Linux,但也想了解Windows和Mac.

如果我有一个内部类声明,例如:

Class A {
    public static class B {
    }
}

其次是:

Class<?> implClass = getClass().getClassLoader().loadClass("A");

A $ B内部类也会被加载吗？如果B内部类没有被声明为"静态"怎么办？

我正在调试一个大的JavaScript代码库,在某些时候,"console"变量在刷新页面时会变为空.

有没有办法在控制台上设置监视并在该值更改时(或条件(console == null)为真时)执行JavaScript中断执行？

我在Windows 7上使用Chrome.

如何使用hbase shell仅打印特定HBase表中的行键？'scan'命令打印出所有列.

我有一个使用此命令的自定义msbuild任务:

var workspace = Workspace.LoadStandAloneProject(csprojPath);

当我运行它时,它会抛出以下错误:

我正在使用Protobuf.net来序列化一些类.我希望能够序列化SuperHero类(如下),而无需在基类上指定[ProtoInclude].这是因为派生类是自动生成的,但基类不是,因此基​​类不直接知道它的派生类.

    [ProtoContract]
    class Person
    {
        [ProtoMember(1)]
        public int Id { get; set; }
        [ProtoMember(2)]
        public string Name { get; set; }
    }

    [ProtoContract]
    class SuperHero : Person
    {
        [ProtoMember(3)]
        public string Powers { get; set; }
    }

我使用的是最新版本的protobuf.net.

我在Visual Studio 2010专业版中有一个C++ googletest项目.这构建了一个生成XML测试结果输出的控制台应用程序.如何设置它以获取代码覆盖率信息？

我已经尝试过这里的指令来检测代码,但查看代码覆盖率结果似乎需要Visual Studio Ultimate.Visual Studio生成的.coverage文件是否有转换器？
