Cppcheck is a analysis tool for C/c++code. Unlike C + + compilers and many other analysis tools, it doesn ' t detect syntax errors. Cppcheck only detects the types of bugs, the compilers normally fail to detect. The goal is no false

In the other use of inline in the previous article, it is mentioned that the function implementation differs from the class definition in the class definition.Now let's look at an experiment:A.cpp:[CPP]View PlainCopy #ifndef Test_h

Topic Three:1) Pre-compilationHandle all comments, with spaces instead,Delete all # define, and expand all macro definitions,Processing conditional Compilation Directives # If, #ifdef, #elif, #else, #endifDeal with # include, expand the files

Default functions in C + + and defaults and delete usagesFirst, the default function in the classA. Default member functions in a class1. Default constructors2. Default destructor3. Copy Constructors4. Copy Assignment function5. Move Constructors6.

In C + +, a static member is an entire class rather than an object, and a static member variable stores only one copy for all objects to be shared. So it can be shared across all objects. Using static member variables to implement data sharing
