Well I know Go caches repositories, but that's not the point.
>>59515598
There is not required version, so the next time author of the repository pushes a broking change or delete the repository clean deployment will fail. This is left-pad shit all over again.

>>59515647
No you fucking retard. you can use "go get" the same way you use "pip install", so if there is and update to a repository, you would have to update it on your computer. You are not directly importing from github. The name of the module is just the same as the github site.

>>59515688
So were do you specify the version of a package you need? Because whatever the source, without versioning the system is broken.
>so if there is and update to a repository, you would have to update it on your computer
Yeah, but what if I do a clean build on a new machine? I will have no other choice but to download the recent version from master, isn't it?

Looking at it, it's a Max Heap. Will probably want to use the 'negative' of distances then. Also note almost no libraries support decreaseKey op's, so you continually add the same node with 'lower' priorities instead (and keep track of 'visited' nodes in a set or something).

If the goal is to key log someone, this would get caught by any antivirus. No obfuscation, no av evasion, no persistence etc. Otherwise, if an exercise, it's a good start.

If you're up for it, maybe have a go at dynamically loading and resolving dlls (like what malware does) so it doesn't reveal much information when the binary is checked with a tool like peid etc

Hook the keyboard functions (not sure if you have to have callbacks from C code to do this in go?). Maybe see if you can detect what hooks your antivirus installs and unhook them(most av will detect this without replacing the hooks or messing with av internals.

        cin >> arrayOfStudents[counter];
        counter++;

It ask me for the first iteration but then just skips the prompt for the rest?

So it looks like

How many students in the class?
4
Name of student 1?
Victor
Name of student 2?
Name of student 3?
Name of student 4?

bcd is the type to read only two numbers of the bignum.
The reason is, bignums are supposed to be theoretically boundless.

>The reason is, bignums are supposed to be theoretically boundless.
So?
I don't see why you wouldn't just make it a bcd pointer.
Being a pointer does not imply any bounds on length.

>>59516792

let the debugger run till the cd message and then pause and look at the stack call frames. There should be a check somewhere deciding or not the cd is in the drive. You can change that check but you'll then have to continue tracing as it might need files that is on the disk etc and you'll have to patch those into the binary etc which can be a real pain. There might also be anti-debugging you have to deal with.

So my output looks like this now:

How many students in the class?
3
Name of student 1?
mouse
Name of student 2?
keyboard
Name of student 3?
monitor
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
11.
12.
13.
14.
15.
16.
17.
18.
19.
20.
21.
22.
23. keyboard
24. monitor
25. mouse
Press any key to continue . . .

Anyone wanna give some suggestions on how to fix?

>>59517387
The initial array is 25 large.
Made it that size because the problem statement asked to prompt the user for a number over 1 and under or equal to 25.

You fucking retard, how was he supposed to know that you were the C++ newbie faggot? I can see it now, but you certainly never made it clear.

>>59517467
I'm sorry :(

>>59517387
It correctly sorted the array. No characters (aka empty set) are considered "smaller" than strings/sets with items in them. If you want it to just print the students you entered, in the for loop make a check that the current student isn't the empty string, and keep an alternative count (for printing student #'s for formatting) that is only incremented when there is an actual student to print.

>>59517361
Lua uses IEEE double, which means that modulo is modulo not a remainder; it is always positive. Which means that math.floor(a) rounds towards negative infinity instead of 0. cdiv() emulates a typical integer division which rounds to zero and can have negative remainders.

>>59517491
I kind of did that.

int list = 1;

for (int i = 0; i < z; i++) {
        if (arrayOfStudents[i].length() > 0) {
            cout  << list << ". " << arrayOfStudents[i] << endl;
            list++;
        }
    }

I don't know how I feel about it but it works.

I'm making this to be compatible with the LuaJIT.

But yeah, if you used it you could implement cdiv as

local function cdiv(a, b)
    a, b = a // 1, b // 1
    return a // b, a % b
end

The massively scalable call

>>59517767
>What function it is supposed to belong to?
It's a common idiom in Lua to return a table from your file, so that users can use it like

local mylib = require "mylib"[/coed]

>>59517767
>What do you mean?

a = a // 1 -- to ensure it's an integer

>What function it is supposed to belong to?
? It's in the script scope. When you load a Lua file, essentially what happens is that the interpreter takes the file and puts it in-between

function() ... end

then executes it in the current environment. But you can return from a require'd file because of that. So you can use require like

local lib = require 'lib'

>>59518184
Haskell automatically decides if it is a bignum or a modulo integer based on the type :)

let x = 10000^8 in (x,x) :: (Int, Integer)

Just implemented generic insertion sort, heapsort, median-of-3 quicksort, and introsort in Rust. They all work for every type that can be compared or copied.

I have to say, it's a pretty nice language to use for this kind of stuff. Coming from Haskell, you go from "how do I even approximate asymptotic memory consumption" to "cool, I can easily compute the worst case stack/heap memory usage exactly".

I can't say I'm actually missing any specific feature from Haskell. I can use all the concrete monadic bind operations I would have used in Haskell, with implementation type-overloaded much like in Haskell.

I found that the Rust standard library actually uses monads much more consistently than the Haskell prelude and every function that can fail returns an Option type (Maybe). Also Rust's type system catches non-exhaustive pattern matches at compile time, while Haskell throws a runtime exception instead.

>>59518471

kys for not knowing how to implement a simple sorting algorithm

>>59516822

Depends on how you want them sorted, normally you move through a linked list or array one offset at a time, check if said offset is greater (or less than depending on the type of sort) and then switch them; then run back through and do the opposite as a check.

Pretty simple once you break it down into small steps, this is second year code monkey stuff

>sorting algorithm

to further what he said, it's something like

function sort(int* j) {
  for(int i = 1; i < sizeof j; i++) {
    if(j[i-1] != NULL) {
      if(j[i] < j[i - 1]) {
        int buf = j[i];
        j[i] = j[i - 1];
        j[i - 1] = buf;
      }
    }
  }
}
