Bind functionPrior to c++11, it was necessary to bind a function, function object, or member function to different parameter values, such as bind1st, bind2nd, Fun_ptr, Mem_fun, and Mem_fun_ref. In C++11, The method of binding parameters is

network communication often involves byte-order conversion, then understand the host sequence and network order what similarities and differences.① host byte order HBO (host byte order)Use small-endian (Little-endian), low-to-high sequential storage.

Asynchronous run (), Run_one (), poll (), Poll_One ()in order to implement a listening loop, the Io_service class provides 4 methods, such as run (), Run_one (), poll (), and Poll_one (). When you use Service.run () Most of the time, you can. You

Immediately after the pointer and domain space we learned, we continued to stroll through the Unreal 4 wiki.1. Odd Shape TI saw Hungarian notation when I was learning to program early, and remember that Microsoft's developer Charles proposed it,

Depending on the result of the operation, other arithmetic shifts and logical shifts have no effect other than the right shift of negative numbers.(It usually happens in negative numbers)Logical right Shift: When you shift to the right, because the

Containers are very convenient and often used to store more than one piece of data, and then the data can be deleted and modified.Sometimes you want to delete a piece of data while traversing, but the program causes the program to crash when you

C language code is organized in a file, in all source files of a source program, an external variable (note is not a local variable) or function can only be defined in one source program, if there is a duplicate definition, the compiler will error.

C++98 the concept of lvalue and rvalue, but the general programmer does not need to understand too deeply, because for c++98, the division of left and right values is generally of little use, but to the C++11, its importance began to appear. The C++9
