Oh fuck is this where that meme came from?

>>56887627
Don't know shit about programming. Is there something that basically would take all even numbers, This seems pretty inefficient, just trying to learn.

>>56888039
Learn the definition of an even number.

>>56888064
I know what an even number is mate. Could yoou do something like this:
>if number can be divided by 2 then output number is even
pls no bully

>>56888159
Modulus. man.
If it equals one, odd. If it equals zero, even.

>>56888159
More precisely
>If number has remember 0 when divided by 2 then output number is even

>>56888187
>remember

My own.

>>56888184
Fuck I totally forgot about that. Thanks senpai
>>56888187
Remember?

>>56887627
>Enters 102
>Your number is odd

>>56888232
Same tbqh

>>56888232
Code reviews make me feel stupid

>>56888039

float x;
if (x/2 == int(x/2)) return "even";
else return "odd";

>>56888184
>>56888288
Slow and inefficient. Do bitwise AND with 1 to check if number is odd.

>>56887711
It's fucking great .

>>56888039
if(/2|4|6|8/.test(number.toString().split('')[number.length])) console.log('even')

Something most anons can agree with at this point is to remove the inline archive.

>>56888288
Wish I had the patience to get into this on my own. What language is this btw.

>>56888337
it's C i think

>>56888221
Remainder

>>56888039
> Is there something that basically would take all even numbers

https://en.wikipedia.org/wiki/Modulo_operation

Finds remainder after division. Only odd numbers leave remainders. So if you check the modulo of a number and it returns a remainder, it's an odd number and if no remainder it's an even number.

In php, $even = $var % 2 ? false : true;

>>56888288
:^)

If Number rem 2 = 0 then 
    Put_Line("Even"); 
end If;

int x
scanf("%d", &x)
printf("%s", (x % 2 == 0)? "even", "odd");

>>56888307
Daily reminder that doing this will do nothing for performance since thw compiler isn't retarded, but will make the code less understandable, especially to beginners, and if you do this, you are just showing off your epeen with no merit.

>>56888039

You have to think of it terms of 'is there a test that I can do which will always tell me if a number is even?'

Such as: 'All even numbers can divide into two equal parts' - so if you divide the number by two and get one left over then it's odd.

>>56888460
We should start a new /g/ thread where we post these images along with correct solutions (or better yet, even worse solutions).

if(x % 2 === 0) {
   document.write("Even Steven! XD";
}
else {
    document.write("That's odd, Todd! haha");
}

... I think the fastest way then would be to read the least significant bit. But I think that only works with integers.

I think you missed the joke there, buddy.

>>56888495
If you need to keep the function call format, even though it's disgusting, you just logical or the inputs and return.

>>56888039

if (!(num & 1)) {
  // Number is even
}

>>56888511
x = y % 2 ? 0 : 1;

The scary thing is that your life might depend on code written by these people.

>>56888522
>I think the fastest way then would be to read the least significant bit.
You can't just read one bit from memory though, you have to read one or more bytes and extract that bit with bitwise operators.

>But I think that only works with integers.
True

A company that I was at a few years ago gleefully told me that they were 'approaching 1 million lines of code'.

When I got to the code I found 50 files containing about 20,000 lines each.

The company had never performed any kind of QA or Code review in 8 years.

A bug in the threading was caused by a poem written by one of the developers kids in the comments commenting over some variables.

This is a great way to make code less readable while adding no value whatsoever.

Look at that horrible code on the left. It was probably written by a fucking white male!

>>56888460
what a shitty code!

function atLeastOneTrue(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z){
    if(Array.prototype.slice.call(arguments).reduce((fu, fug) => fu+fug)) return true
    if (!Array.prototype.slice.call(arguments).reduce((fu, fug) => fu+fug)) return false
}

I don’t think this is real honestly

I think I was thirteen when I first had to do this, and I was smart enough to compare rounded and unrounded quotients

>>56888648
Depends on your priorities. I work on real-time systems so we do stuff like this all the time.

>>56888664
Nothing wrong with Visual Basic per se, it's good for simple UIs as long as you know what you're doing.
Of course, you don't want to make pacemaker *firmware* with it.

>>56888793
Even the shittiest compiler will optimize that comparison. It's just a bad habit that serves no purpose.

>>56888793
Trust me, compilers these days are smart enough to omit division instructions when it encounters a % 2.
If your compiler doesn't to that it's probably from the 70s or something and you might consider upgrading.

>>56888851
It's not Pascal.

That is also part of the problem.

m8 it's easier than that. You can solve it with basic math.
