    Choosing the path of where to read/write

    Hi again.

    Finally, I'm done with my assignment... except for one thing !!
    It seems the specification sheet I got for the assignment didn't provide where.
    However, an example was given. Example is to use a server then two clients (as the server's argument). What happens here when I run two client examples, they write and read from where they are located.

    When it's about my program ( I used Visual C 2005 ), the read/write happens in the .../(projectname) file.

    Is there a way to make my program portable and let it read wherever it the (projectname).exe is located, or should it be specified ?

    my read example:
    void main(int argc, char* argv[])
    int i, t;
    	for (i=0 ; i<argc; i++)
    for (t=1; s->tank1Alive=="true" && s->tank2Alive=="true"; t++)
    FILE *outfile, *infile;
    char buffer1 [30]; // for STATE file
    sprintf(buffer1, "p%dt%03d.state", i, t);
    infile = fopen (buffer1,"r");
    fscanf(infile, "%*s %d %d\n",&s->mapDimensionsX, &s->mapDimensionsY);
    Thanks for reading my problem

    I don't understand exactly what 's your question.
    Do you want to r/w a file in the same path where you executable is?
    If yes, you can use
    LPTSTR GetCommandLine(void);
    this function returns an unraveled argv[], with the exe's path in double-quotes in front.
    It works wor windows only.

    It alreay is doing that. Just copy the program to some other folder and you will see it write in that new folder.

    BTW: There is no such compiler as "Visual C 2005" -- just being nitpicky

    >>void main
    Its int main(), never ever void The C and C++ standards require main() to always return an int. Anything else is non-standard and non-portable.
