Method
When the author of this book first started learning C and, later, C++, he used to
write small pieces of code, compile them, and then look at the assembly language
output. This made it very easy for him to understand what was going on in the
code that he had written. He did it so many times that the relationship between
the C/C++ code and what the compiler produced was imprinted deeply in his mind.
It ’ s easy to imagine instantly a rough outline of C code ’ s appearance and function.
Perhaps this technique could be helpful for others.
Sometimes ancient compilers are used here, in order to get the shortest (or sim-plest) possible code snippet.
