    in your .bat file you should just need 2 commands: first run the command to compile the program, then on the next line type the name of the file. (both assuming current directory, otherwise specify complete path, of course).

    thats the easy part. what you need to know is the command to compile your source code, which i imagine would be on the compiler's website or in its documentation.

    Is there any particular reason that you want to do this?

    Anyway, assuming MinGW is in your path, something like this should work.
    Code:
    g++ program.cpp -o program.exe
    program.exe
    You might want to specify the paths to program.cpp or .exe, etc.

    You can also compile multiple files this way, by specifying more than one .cpp file -- or you can only compile the .cpp files that need compiling . . . but you quickly lose track of which ones need recompiling and which ones do not.

    If you start using multiple source files, use make. Even if you're only using one source file, a Makefile can make (sorry) your life a lot easier.

    Here's a very simple makefile to compile program.cpp into program.exe.
    Code:
    program.exe: program.o
    	g++ program.o -o program.exe
    
    program.o: program.cpp
    	g++ -c program.cpp
    Save that as "Makefile", type make, and bam, away you go. (Or call it whatever and use make -f whatever.)

    Note that you have to use tabs in Makefiles. Not spaces.

    If you want to learn more, find a make tutorial. There are lots out there.

    So what happens if the compilation fails?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Can you be more specific than "it doesn't work".
    Does it for example complain about not being able to find gcc.
