The statement #include is used in C++ to include the source file or import the header files containing definitions of function declarations, macro definitions to be shared between several source files and variables using the preprocessor. On the other hand, #import is a Microsoft-specific statement used for binary library like DLL or .Lib files. It is very similar to include that it load all the header function definitions from the DLL file so that the user can use the header file just like the case with #include.
The statement #include allows the user to include the same file many times while #import ensures that the preprocessor only includes a file once.
