One, manual initialization of built-in type objects, because C + + does not guarantee that they are initialized. The object initialization data member is done before entering the constructor user to write the code, in order to specify the

Initialize the member as much as possible using the member initialization method; C + + stipulates that member initialization occurs earlier than the constructor, and constructors are best to use the member initial column rather than using an
