usually defined as an integer value. And as the standard changes, the __cplusplus macro will generally be a larger value than the previous table.For example, in the C++03 standard, the value of __cplusplus is predetermined to 199711L, and in C++11 Standard, the macro __cplusplus is predefined as 201103L. This change can be used for the code.For example, when a programmer wants to make sure that the code is

The terminal processing of Linux systems is a very large system that needs to deal with many different types of devices and requirements. The content includes: modem, terminal emulation, pseudo terminal and so on.
The way the Linux system handles the terminal is to communicate with the system and run the program through a serial interface connected to the console. Because more and more manufacturers are involved in the production of terminals, and each manufacturer for their own terminal design

C ++ concurrent programming learning notes Getting started
What does a multi-threaded C ++ program look like?
It looks like all other C ++ programs, usually a combination of variables, classes, and functions. The only real difference is that some functions can run concurrently,
Of course, to run functions concurre

1. What is hosting C ++?
To answer this question, you must first understand what is managed ). Hosting is. net is a new programming concept integrated with the general language runtime (CLR). Therefore, we can regard "hosting" as ".. net ". So what is "general language runtime "? The general language runtime is the execution lead of. NET Framework applications. It provides many services, including code
