Constants
In C++ we learnt that a variable is a container (storage area in memory location) to hold data (integer numbers, floating numbers, strings etc.), Also we explain that the placement of variable definitions as given above is very important. Generally they should be declared before all, at least before the usage. You can declare all given types above as a global variable or local…

If you are looking to a way to reliably determine whether C++ code is being compiled in 32 bits or 64 bits there is way to check in C++ code.
For a cross platform compilation (cross compiler environments like FireMonkey framework in C++ Builder) there is no single reliable method to check if your application is running as a 32bits or 64bits application. Note that lower bits applications (i.e…
