Chained Ternaries

UseCase:

You need to fork/exec a program. You need to pass CommandLine options based on variable bound information. You want to be concise.

Example:


        int main(int, char**)

        {

        int geometry = metrics::large;

        const char* args[] = {

        "program",   // arg0 is always the program name

        "-geometry", // specify the geometry

        false ? 0

        : metrics::large == geometry

        ? "1024x768"    

        : metrics::small == geometry

        ? "640x480"

        : "default",

};


        // error checking omitted for brevity

        execv(args[0], args);

        return 0;

        }

Is it just me, or is this TooCleverByHalf? I think the equivalent code without chained ternaries is just as readable.

A collegue pointed out that it isn't the simplest possible thing, and that an IdiotProgrammer doing maintenance might not get it...
