In these examples, we will discuss another way to declare variables with the method of “extern.” External variables can also be referred to as global variables. The functions can change the values of global variables. The term “extern” is used to declare and define external variables. Thes...
String[] myStringArray = new String[3]; // each element is initialised to null String[] myStringArray = {"a", "b", "c"}; String[] myStringArray = new String[]{"a", "b", "c"}; The third way of initializing is useful when you declare an array first and then initialize it...
I had no luck searching the GCC documentation. I thought I might have the var automatically used globally inside the same macro but I couldn't think of any way to do it. Does anyone know of a way to hide that warning in GCC? Just saw this thread while searching for solutions to this...
When a storage device is connected to Windows, even if only briefly, windows creates registry information for the device. Over time, the registry may contain many entries for devices that will never be used again. This article describes how to remove this ...

Learn how to define value equality for a class or struct. See code examples and view available resources.
You can provide code for a data method by using C# or Visual Basic. The default template that is used for a data method is provided in C#. This topic describes the steps to define a report data method in C#. You can use a data method for advanced scenarios to retrieve and manipulate ...
Globals::administrativeData= NULL; But the error is "cannot convert from 'int' to 'administrativeData'" Probably a better name would be "C++/CLI" (at least this is what your "C++/CLR" makes me think). "NULL" is an old pre-C++11 constant. In modern C++11, a better choice is "nul...
If we are unable to use the assert() function, we must be disabled, so ndebug should be defined. It was decided to declare it using #define NDEBUG code; otherwise, the code compilation should pass. -NDEBUG in the code. The code compilation will pass -DNDEBUG to disable the assert() fu...
When we compare two function pointers then we have to remember that two pointers of the same type compare equal if and only if they are both null, both points to the same function or both represent the same address In your program, if the function pointers are not initialized by the valid...
