---->
CODE: code segment will contain machine language code.
DATA: Global variables
STACK:Local variables
HEAP:Used for dynamic aloocation.

---->
BSS:this is Block Started By Symbol: Static variables goes here

--->
I don't know about windows, But when compiling with gcc
you can avoid flags -g,-ggdb
also add flags like -O1,-O2,-O3 etc this decides optimization level.
Remember that, more optimized code is more difficult to debug

BSS:this is Block Started By Symbol: Static variables goes here

This is not true; the DATA segment contains all global variables, whether static
or not, that are explicitly initialized. The BSS segment contains all globals that
aren't explicitly initialized; they're all zero so the segment can be constructed
instead of loaded from the COFF or ELF file.

kind regards,

Jos
