    Help with debugging a program which needs the command prompt

    Hi!

    I'm a very beginner in programming and I would like to debug a program to know how it works, because its code is pretty big.

    The compilation was ok, and my problem is: the program needs the command prompt to run the executable and set its input/output files, so I have to type something like this on the prompt:

    C:\...\epanet2d input.inp report.rpt output.out

    Then, because the program needs this information, when the debugger calls the executable, it opens and closes without passing by the main routines (I guess).

    Might anyone help me with this?
    What should I do?

    ps. I'm using code::blocks

    Thanks! =)

    I've never used code::blocks before, but I did a Google search and found this:

    Project --> Set programs arguments?

    From what I remember, you have to wrap your program in a project and have a debug build configured in order to use the debugger in the IDE.

    This should get you started:

    Debugging with Code::Blocks - CodeBlocks
    1. Get rid of gets(). Never ever ever use it again. Replace it with fgets() and use that instead.
    2. Get rid of void main and replace it with int main(void) and return 0 at the end of the function.
    3. Get rid of conio.h and other antiquated DOS crap headers.
    4. Don't cast the return value of malloc, even if you always always always make sure that stdlib.h is included.
