Raise questions:When writing a program, sometimes only one pointer variable is defined in the main program, and a dynamic array pointed to by this variable is created in the subroutine and assigned a value. In this case, you only need to ensure that the real parameters and form parameters point to the same address.Routine:Main Program:Main Program:

Premise: When xcode is used for development and debugging, it is often necessary to print some debugging information for debugging. As you know, when there are too many information to print, it may not be a problem to run on the simulator, because the simulator uses computer hardware, but when the application runs on the device, these output statements will greatly affect the application performance, to solve this problem, you can write some macros to control the output of the debugging informat
