Stack and Heap
In the previous chapter, we ran an investigation of the memory layout of a running process. System programming without knowing enough about the memory structure and its various segments is like doing surgery without knowing the anatomy of the human body. The previous chapter just gave us the basic information regarding the different segments in the process memory layout, but this chapter wants us to just focus on the most frequently used segments: Stack and Heap.
As a programmer, you are mostly busy working with Stack and Heap segments. Other segments such as Data or BSS are less in use, or you have less control over them. That's basically because of the fact that the Data and BSS segments are generated by the compiler, and usually, they take up a small percentage of the whole memory of a process during its lifetime. This doesn't mean that they are not important, and, in fact, there are issues that directly relate to these segments. But as you are spending...
