    Why is my .exe file so big

    I wrote a simple connect 4 game but when i compile it, the .exe turns out to be 400+ kb big
    Im using the latest Dev C++
    I remember I compiled an even more complicated version of my game using MSVC 6 and the file was only 50 kb

    How (if possible) do i make DevC++ compile my game more efficiently?

    Make sure you turn off debugging symbols.

    GCC always creates huge files.
    According to Dante Shamest (don't know if he is here, but he is at cpp-home.com), it has to do with expanding templates:

    Tools > Compiler Options > Settings > Linker > Generate debugging information > No

    Have you read MinGW's FAQ on this topic?
    http://www.mingw.org/mingwfaq.shtml#faq-C++size

    What about Dev-C++'s unoffical FAQ?
    http://www14.brinkster.com/aditsu/dev-cpp-faq.html
    C + C++ Compiler: MinGW port of GCC
    Version Control System: Bazaar

    well there is something i didnt know.

    The default syntax for the actual statements is AT&T, which is quite different from the well-known Intel syntax. However, you can switch to the Intel syntax by adding -masm=intel to the compiler options.

    Holy crap thats off topic!! However quite a golden gem piece of information. Thanks, I always just compiled with masm32 and linked normally. Anyway, i played with quite file sizes and exes a bit seeing what works with gcc vs. vc++, when fully optimized and and without debugging the gcc produced exes are almost always about 5-50k larger on very small executables. Sometimes the sizes are very similar. But its noteworthy to mention on a very large project the size difference, percentage-wise, only gets smaller and smaller. The difference in size is always about 5-50k depending on what you are doing.

    Along those lines, gcc and visual c++ have different default environments. Some things are on by default in gcc that will increase the file size, whereas they are off in visual c. The real jump that kills me is when i write stuff in assembler that I know will result in an exe about 10k with either compiler and the assembler output is like 1.5k. Thats always a sweet jump. Unless there is a size requirement for your program (i.e. you need to make a big program fit on a floppy) i don't see why it matters in any event.
