The memory layout in the C programming language can be divided mainly into 4 zones or segments.
The first one is the .text segment, which contains the program instructions. Then we have the segment containing the global and static variables, which in turn is divided into bss and ds register. The next segment is the stack which we have already talked about in other classes of this C course and finally we have the heap segment which is the one destined to the dynamic memory.
The latter is the one we will understand in more detail given the importance of dynamic memory in the C programming language.
