Read the chapter entitled "Memory" in my book Safe C++ Design Principles
(available to c-prog members for free - see the Books section of the
website). It describes how memory is allocated on many systems and most
likely explains why your program didn't crash.
And you should not be writing C code. Write at least C++ code or,
preferably, Safe C++ (or at least using the concepts of Safe C++ in C++
code).
