Absolutely Pointless And Completely Random!

[Takara]

Hey, look! I put the entire description of ME in only five words! That must be a new record! =D

Okay, so, I'm completely and utterly bored. Why don't we do a completely random interview-quiz thing like they do on super-cheezy TV shows to amuse ourselves? I'll be the host. (shuffles note cards) XD Now what contestants do I have the pleasure of introducing and interviewing?

[Briar]

Haha, goodness you must be bored.

edit: sorry, didn't mean to make fun. :P

I'm Briar btw.  Nice to have ya here at RWL.

I played ME once
it sucked
we destroyed the Borg

Carbz is awesome

[Briar]

we destroyed the Borg

sounds like someone is still part of the collective.

Hai. My name is Krowdon and Tacos are yummy.

ME == Mechanical Engineering?

[Shadow]

bjorn = (ME==mechanical engineering) ? foo : bar;

[Krowdon]

i like paper Cranes.

[Gorak]

and now for something completely random

[Ungatt Trunn II]

[bjornredtail]

bjorn = (ME==mechanical engineering) ? foo : bar;

Compiler Error: Statement With no effect.

* bjornredtail tries it...

NO way... There's just no way... that acctually compiles?

* bjornredtail tries with -wall flag

Oh, okay.

Code Select Expand

int main(int argc, char *argv[])
{
    int bjorn;
    int ME;
    int mechanical_engineering;
    int foo;
    int bar;

    bjorn = (ME==mechanical_engineering) ? foo: bar;

    return EXIT_SUCCESS;
}

Oh, right...
So, if ME == mechanical_engineering, then bjorn is set to a non-zero value (true) and foo is set to the same non-zero value. If ME != mechanical_engineering, then bjorn is set to 0 (false) and bar is set to 0.

That exression is equivlent to:

if (ME == Mechanical_engineering)
        bjorn = foo;
else
        bjorn = bar;

but apparently it doesn't care if any of the variables are given values prior to the call? That's new to me, and I will definitely remember that on the off chance that I ever use that in real code.

Lol, I like C and all it's completely unnecessary equivelent control structures. I don''t like the random assigning of values that happens if you screw up, it makes debugging a pain in the butt.

WHats a -wall flag? :P

You are right about the ternary ? (http://en.wikipedia.org/wiki/%3F: , I had to look it up).and you are more or less correct on the variables. C does not initialize variables. They are whatever random crap happened to be in the memory before things happened. So, the ME = Mechanical_engineering is almost random. Of course, it is most likely going to be 0, but that's besides the point. foo and bar are also crap. So, the value of bjorn is meaningless at the end of the program... That's why I didn't initialize my variables.

-Wall turns on all warnings in GCC.

gcc  -o -wall program_name source_file?
