I noticed this on my second program, I made hello world with only "Hello World!" on the text and another one with a few lines.
Hello World is 180 KB (the exe) and the one with a few lines is (500+KB) Why?? I use Visual Studio 6.0, why so big? are they supposed to be that big?
Probably because VC++ does debug with the code, and when you debug, the file is larger than normal.
the standard version of VC++ does not optimize as much as say, the enterprise edition
So what your saying i make a file with 1 line is 200 KB, then a file like a game engine or full software will be around 2-3 gigs or something? Thats not possible
It has to do mostly with optimizing, and a little with include files. When your program is compiled, it is transalted into asembly which is a lower level language than C++. When the compiler is on debug instead of release, it does not optimize the code, meaning the translation is not as effecient as it would be on release. Also, include files like iostream, fstream, conio... are pretty big, especially iostream. I hope this answers your question.
Ya I kinda get it now, but lets day if you add like 20 iostream, does that add up all 20? or does it link to the only one it includes to the exe
iostream.h, like every class to my knowledge, has preprocessor commands "#ifndef ___" "#define" CODE HERE "#endif". If it is already defined, it will not do it again. No matter how many times you type #include<iostream.h> it will only be included once.
Full sized games might be as large as a couple megs. If you put your compiler into release mode, or to turn on optimizations, and turn of debugging, the code will be a lot smaller.
For example, the program that I'm working on goes from 253 Kb in debug compiled, down to 88 Kb in release compiled. And that's just the standard, there's lots of things I could do to reduce that even farther. Oh, and my code is around 25 pages long.
howdy,
where can i find doc's that detail the different compiler switches that turn on/off things like debug, release, optimization......
i use gcc 2.96 and BCB 5.

You have probably compiled the debug version, look into your project settings and change to release version. Then you will see that the program us much smaller.
The program isn't only 1 line, #include <iostream.h> iostream.h is probly like 1000 lines
OIC but how do I change it to release mode anway?
Build->Set Active Configuration->Release
Assuming you're using VC++.
Alright cool I did one with like 30 lines of text and its only 30 KB thanks a ot all
I was gonna say, 180k!
The game I finished a while back had a TON of stuff in it, and it was 800k. It was like 400 MB in artwork as well :D
for gcc use -O2 to optimize it.Quote:
