That seems pretty big. Im using DevC++. Is that normal?O ya and can someone tell me how to create one of those white boxes in a post so i can put my coding in it and it wont look so big.

It is easily possible to get small EXEs with Dev-C++, you just need to know how. Make sure you have Best Optimisation turned on, and Generate Debugging Information turned off. Then, add -s to the linker command-line paramaters. If that doesn''t give you small enough, get UPX and compress the executable. My tetris clone becomes <50k when using the above techniques.

One possible size optimization is to write the module prologue yourself, and not link to the c++ runtime libraries at all.
However, this is relatively difficult compared to other suggestions here.

what does the -s option do? I''m looking to do the samething for my programs too but I''m using Borland''s compiler and I was wondering if there''s a similar option under that? I already have debug info turned off and have optimisation set to create smallest possible exe. But the resulting exe file is still well over 100k for a simple console program.
