/prog/ - Code that may or may not pass muster

Name: Anonymous 2009-10-01 2:42

I know we've got some computer science students in here, and I know you've written some questionable code at 2:30 in the morning before your project is due. So post it here! Preferably one-liners. Here's mine. I'm interested to see what my prof thinks of it... opinions could differ.

printf("%.1f%c", *e, (0 == (e - matrix + 1) % size)?'\n':'\t');

printf
Problem found! printf will bottleneck your code, especially when dealing with matrixen'

Don't worry, anyone spending much time running this program must be looking to waste their time anyway.

printf("%.1f%c", *e, ((e - matrix + 1)%size)?'\t':'\n');

Better.

The zero is there so readers know I'm comparing for numerical value. And why didn't you get rid of the extra parens if you're into pointless minimalism?

The compiler takes no heed of extra parens and it will result in exactly the same compiled code. You're comparison on the other hand..

My are comparison will make use of an instruction like x86's JNE.

Several clock cycles slower than using JNZ.

printf("%c", ********c);

That was pretty deep

Name: Anonymous 2009-10-01 8:33

one of my favorite beautiful pieces of c is this switch technique:



switch(foo) {

  case 1:

    s = "one";

    if(0)

  case 2:

    s = "two";

    if(0)

  case 3:

    s = "three";

    blah(s);

    break

}

no, it means it skips the first line of the next case, but then continues. this allows a common section for the 3 cases, but also specific code for each

ENTERPRISE QUALITY

i wrote this today.
i don't think it's actually very bad, but i felt kinda bad about it because i've always been told that gotos are bad mojo.

while((c = getchar()) != EOF){

   int i;

   for(i = 0; i < str1_len; ++i){

      if(c == str1[i]){

         goto next_outer;

      }

   }

   putchar(c);

   next_outer:;

}

in case you're wondering, what it does is prettymuch the same as tr -d
