Question #1 : What you can do is to check the compiled object file (.obj) where you can see the result of the compilation (before linkage). Check http://en.wikipedia.org/wiki/Object_file for details. But this is not exactly what you want and I don't know of a tool to 'expand' C/C++ source code and show you the result. Of course, you can search for such a tool, it may exist, or maybe check for some compiler options to do that.
Question #2: You can find a detailed answer here : http://experts.about.com/q/C-1040/message-box.htm Question #3: Well, you can always read the header files :). Otherwise, from what I know you can directly got to the type / function definition using a shortcut in VS7. I didn't try with VS6. Question #4: Yes, this is correct. The explanation is that the compiler transforms indexing operator [] in the content of the memory location at adress 'a' indexed by 'i'. a[i] is equivalent with *(a+i) which is the same with *(i+a) (addition is commutative). And because i[a] is *(i+a), a[i] == i[a]. You should really study pointers and pointers operations. It's very important knowledge if you want to learn C. Hope this helps. Question #1 Is there any way to do the precompile and output it to a file ? I want to look at the expanded source with all the includes and conditional stuff. Question #2 The demo "Hello World" program starts with - int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) I'm trying to figure out what the APIENTRY is ? If it is a type then I looked in all the include files to see were it might be defined and can find no reference to its definition. #3 As a more general question, I see many references to types and am trying to figure out an easy wasy to track them back to the source of definition so that I might see what they are. Is there any easy way to do this ? #4 >From WIKIPEDIA - x[i] = 1; *(x + i) = 1; *(i + x) = 1; i[x] = 1; /* strange, but correct */ Supposedly all 4 examples yield the same results. They listed the last example just because it demonstrates something that doesn't seem correct but works. But they left the explanation out. = = = = I've got a bunch more questions, this is quite overwhelming at first. If anyone wants to offer some tutoring, I wouldn't mind the help. Thanks a lot. <!-- #ygrp-mlmsg {font-size:13px;font-family:arial,helvetica,clean,sans-serif;} #ygrp-mlmsg table {font-size:inherit;font:100%;} #ygrp-mlmsg select, input, textarea {font:99% arial,helvetica,clean,sans-serif;} #ygrp-mlmsg pre, code {font:115% monospace;} #ygrp-mlmsg * {line-height:1.22em;} #ygrp-text{ font-family:Georgia; } #ygrp-text p{ margin:0 0 1em 0; } #ygrp-tpmsgs{ font-family:Arial; clear:both; } #ygrp-vitnav{ padding-top:10px; font-family:Verdana; font-size:77%; margin:0; } #ygrp-vitnav a{ padding:0 1px; } #ygrp-actbar{ clear:both; margin:25px 0; white-space:nowrap; color:#666; text-align:right; } #ygrp-actbar .left{ float:left; white-space:nowrap; } .bld{font-weight:bold;} #ygrp-grft{ font-family:Verdana; font-size:77%; padding:15px 0; } #ygrp-ft{ font-family:verdana; font-size:77%; border-top:1px solid #666; padding:5px 0; } #ygrp-mlmsg #logo{ padding-bottom:10px; } #ygrp-vital{ background-color:#e0ecee; margin-bottom:20px; padding:2px 0 8px 8px; } #ygrp-vital #vithd{ font-size:77%; font-family:Verdana; font-weight:bold; color:#333; text-transform:uppercase; } #ygrp-vital ul{ padding:0; margin:2px 0; } #ygrp-vital ul li{ list-style-type:none; clear:both; border:1px solid #e0ecee; } #ygrp-vital ul li .ct{ font-weight:bold; color:#ff7900; float:right; width:2em; text-align:right; padding-right:.5em; } #ygrp-vital ul li .cat{ font-weight:bold; } #ygrp-vital a { text-decoration:none; } #ygrp-vital a:hover{ text-decoration:underline; } #ygrp-sponsor #hd{ color:#999; font-size:77%; } #ygrp-sponsor #ov{ padding:6px 13px; background-color:#e0ecee; margin-bottom:20px; } #ygrp-sponsor #ov ul{ padding:0 0 0 8px; margin:0; } #ygrp-sponsor #ov li{ list-style-type:square; padding:6px 0; font-size:77%; } #ygrp-sponsor #ov li a{ text-decoration:none; font-size:130%; } #ygrp-sponsor #nc { background-color:#eee; margin-bottom:20px; padding:0 8px; } #ygrp-sponsor .ad{ padding:8px 0; } #ygrp-sponsor .ad #hd1{ font-family:Arial; font-weight:bold; color:#628c2a; font-size:100%; line-height:122%; } #ygrp-sponsor .ad a{ text-decoration:none; } #ygrp-sponsor .ad a:hover{ text-decoration:underline; } #ygrp-sponsor .ad p{ margin:0; } o {font-size:0;} .MsoNormal { margin:0 0 0 0; } #ygrp-text tt{ font-size:120%; } blockquote{margin:0 0 0 4px;} .replbq {margin:4;} --> ____________________________________________________________________________________ Yahoo!
