The android Java SDK is nice and all, but what if you want to runSome C service or code? Well, it turns out that this isn' t exactlyDifficult. You can compile an application using a standard LinuxCross-compiler, install it and run your programs from

C ++ inline functions 1. Differences between inline and macro definitions (1) inline is related to the compilation period, while macros are related to the pre-processor, which are not processed in the same period. (PS: General high-level language

When C ++ does not have a template mechanism, we use a common function. To implement an addition function, it can sum two parameters, and return values of the appropriate type based on the parameter type, you must manually write all the code:Short

Simply put, a process copies a piece of code into multiple copies and allows them to execute them simultaneously. Inter-process communication aims to make them run in an orderly manner. In short, threads allow multiple functions to be executed at

Debug is usually called a debug version. It contains debugging information without any optimization, so that programmers can debug programs easily. Release is called a release version. It is often optimized to optimize the code size and running
