Working with Time Problem You would like to write portable programs that are aware of the current time or their execution time. Solution Modern C++ provides STL templates and classes that provide portable time handling capabilities. How It Works Getting the Current Date and Time C++11 provides access to different real-time clocks in a given computer system. The implementation of each clock may be different depending on the computer system that you are running on itself however the general intent of each clock will remain the same.

The problem here is that C++11 lambdas do not support the auto keyword as a parameter. Building Listing 2-24 with a C++11 compiler results in the following output. cpp:35:2: note: candidate template ignored: couldn't infer template argument '$auto-0-0' [](auto&& number){ ^ 4 errors generated. makefile:2: recipe for target 'main' failed make: *** [main] Error 1 Thankfully this is a much clearer message than when trying to compile Listing 2-23 and it’s reasonably clear that C++11 does not support auto type deduction for lambda function parameters.

Cpp:17:24: error: constexpr variable 'ARRAY_SIZE' must be initialized by a constant expression constexpr uint32_t ARRAY_SIZE{ ArraySizeFunction(15) }; 30 Chapter 2 ■ Modern C++ Two warnings are presented to show that the constexpr function cannot be used in a constexpr context. This is not a compile error because the function can still be used in a non-constexpr context. The actual error is thrown when the function is used to initialize a constexpr variable. Recipe 2-6. Working with Lambdas Problem You would like to write programs that utilize unnamed function objects.
