What version of C++ does Google use?

Google has one of the largest monolithic C++ codebases in the world. We have thousands of engineers working on millions of lines of C++ code every day. To help keep the entire thing running and all these engineers fast and productive we have had to build some unique C++ tools, centering around the Clang C++ compiler.

Are templates runtime?

However, templates are instantiated at compile-time and thus cannot be instantiated with types that are only known at runtime. This is where the type erasure pattern comes in.

What is Constexpr in C ++ 11?

The keyword constexpr was introduced in C++11 and improved in C++14. constexpr indicates that the value, or return value, is constant and, where possible, is computed at compile time. A constexpr integral value can be used wherever a const integer is required, such as in template arguments and array declarations.

What is compile time C++?

Compile-time is the time at which the source code is converted into an executable code while the run time is the time at which the executable code is started running. Both the compile-time and runtime refer to different types of error.

What is compile time and runtime polymorphism in C++?

C++ Compile-time Polymorphism vs Run-time Polymorphism Also called dynamic or late binding. Achieved through overloading. Achieved through overriding. The function to be executed is known during compile time. The function to be executed is known during run time.

Does Google still use C++?

Alphabet hires C++ developers as Google cloud engineers, network and system specialists, security experts and database engineers. Investment banks, hedge funds and high frequency trading funds are also big users of C++ expertise in high speed trading systems.

What causes a compile-time error when using a namespace?

In any other context, an expression classified as a namespace causes a compile-time error. A type.

Does MSVC conform to the C++ standard?

The MSVC compiler toolset in Visual Studio version 15.7 now conforms with the C++ Standard. For more information, see Announcing: MSVC Conforms to the C++ Standard and Microsoft C/C++ language conformance.

Why do I get compile-time errors when using an expression?

Most of the constructs that involve an expression ultimately require the expression to denote a value. In such cases, if the actual expression denotes a namespace, a type, a method group, or nothing, a compile-time error occurs.

When was the first draft of the C++ standard published?

The first draft for formal comments was produced in September 2008. The Final International Draft standard (FCD) unanimously approved by the ISO C++ committee on March 25, 2011. It was formally approved by a 21-0 national vote in August 2011. The standard was published this year (2011).
