Can someone tell me what is a \'text segment\' in C, and if possible show me a simple example?

    The 'text' segment of a program on Unix systems is the code — the machine code, the functions that make up the program (including, in particular, main() if the program is written in C or C++). It can also include read-only data. The other segments in a classic program are the 'data' segment and the 'bss' segment. The 'data' segment holds initialized data; the 'bss' segment holds zeroed data. Once running, the data and bss segments are indistinguishable.

    You also end up with the stack and 'the heap'.
