Yes. Include files can be nested any number of times. As long as you use precautionary measures, you can avoid including the same file twice. In the past, nesting header files was seen as bad programming practice, because it complicates the dependency tracking function of the MAKE program and thus slows down compilation. Many of today's popular compilers make up for this difficulty by implementing a concept called precompiled headers, in which all headers and associated dependencies are stored in a precompiled state. Many programmers like to create a custom header file that has #include statements for every header needed for each module. This is perfectly acceptable and can help avoid potential problems relating to #include files, such as accidentally omitting an #include file in a module. read less

Most of the include files (Header Files) fro STL and C libraries are nested. Very common practice to do it, or rather it becomes unavoidable when you start writing bigger/complex code.

Yes. you can include. but it will increase the size of the binary. Use the conditionaly compilation to avoid more than one time inclusion.
