Instead of spamming the DT why not use something like this?

function love.load()
  local debugGraph = require 'debugGraph'

The only thing LuaJIT needs is continue/bitwise operators and I'd switch to using it fulltime.[/QUOTE]

I added continue to LuaJIT some time ago as part of a module that would replace the Lua implementation in Garry's Mod. It's not really useful for that anymore, but it's still LuaJIT with a continue keyword. There's no bitwise operators though (but who needs them when you have a perfectly usable bit library).

Hey guys! New to Facepunch, just wanted to introduce myself.
Aspiring coder here, its safe to say I know around 6 languages. Hoping to learn more.
Anyway,
Here's what I coded in C++ after only doing it a day. Learning C++ for UE4 game development and hope to make some pretty good video games. Someone said I have a really weird unorganized coding style. Is it all that bad?

#include <iostream>
#include <stdlib.h>
#include <string>
#include <cstdlib>
using namespace std;

int guess;
int tries1;
int answer = rand() % 101;
bool playAgain;
int wouldYouLikeToPlayAgain();

void repeat() {
      if (guess < answer){
         cout << "The answer is greater then what you guessed!" << endl;
      } else if (guess > answer){
         cout << "The guess is less then what you guessed!" << endl;
      }
}

int main() {

    cout << "Guess a number I'm thinking off thats between 100 and 1! ( They can only be integers )" << endl;
    cin >> guess;

    if( guess == answer ){
        cout << "You guessed the right number!" << endl;
    }
    repeat();
    wouldYouLikeToPlayAgain();

}

int wouldYouLikeToPlayAgain(){
    playAgain = false;
    int playA;

    do{
        cout << "Would you like to play again? ";
        cout << " 1 / yes 2 / no" << endl;
    } while ( playAgain = false );
    cin >> playA;
    if ( playA == 1 ){
        main();
    } else if ( playA == 2 ){
        return 0;
    }
}

If coding style is a little weird it might be because I'm coding in Qt on a chromebook lmao

It's bad to call main() manually, and because you're technically using main() as a recursive function (main() calls a function that calls main()), so you'll end up with a stack overflow at some point.

And since you're not setting a seed for rand(), the sequence of answers is always going to be the same.

And your "do {} while(playAgain = false)" is incorrect, you should use two equal signs. Right now you are assigning false to playAgain, so the whileloop will run once, then stop executing, because the statement is always false.

That is not the point. Seeds are there to generate unique random numbers (pseudo random, but not relevant right now).

If you don't set a seed, and you run your program, a possible outcome of calling rand() 10 times modulo 100, could result in the following numbers:

20, 8, 48, 1, 90, 58, 32, 41, 88, 39

The 2nd time you run your program (stop it, start it again), it'll have the same outcome, because the seed is the same (not set to anything different). Use srand(time(NULL)) (just an example) to set a random seed.

Running this program will generate the same output every time you run it: [url]http://cpp.sh/9wweh[/url]

i guess that the problem with this is that you're mixing c and c++ code together which looks bad

i'd suggest to only use stuff from modern c++ (c++11 and up) and not touch the c standard library at all

although if you're only going to use c++ in unreal then its probably fine

i dont know if unreal even uses modern c++

at least the source engine uses some kind of ancient form of c++ and their own standard library which is pretty much c so the code you write ends up looking like the code you wrote above

[editline]7th January 2016[/editline]

also in the beginning you're doing

if (guess < answer){

but then later on you're doing

if ( playA == 1 ){

whichever is fine but you need to be consistent

try to get into the habit of not using global variables when you could use local variables instead - while it doesn't matter in a small project, if you're looking to make games and you're using global variables it'll pollute the namespace and become an absolute nightmare. Global variables are generally considered bad practice.

For example, declare your guess integer inside main, and pass it into repeat to run your comparison, instead of accessing it globally in both functions.

Also, generally, don't call main recursively.

[editline]8th January 2016[/editline]

Also your main function doesn't return a value even though its defined as an int. The program probably isn't affected by that but you should really make it return some sort of int. The same goes for wouldYouLikeToPlayAgain() - if the user types in unknown input there's no value returned which might cause a runtime error - because you've used an if, else if with no else.

I'm not going to disagree with the validity of your code but maybe, just maybe, what you're suggesting might make no sense to another programmer. Honestly for the intended purpose I think you're nitpicking.

rand() might be less desirable for any number of reasons but for RNG most people are familiar with it and it hasn't presented itself as problematic for the majority of us.

Are you insane? Are you actually suggesting a new C++ developer to use a deprecated and potentially unsafe way of generating pseudo-random numbers instead of doing the right thing and using C++11?

Let's begin by making the code snippets equivalent.

Good version:

// Seed provider
std::random_device rd;

// Set a sane seed
std::minstd_rand g(rd());

// Generate number in range [1, 11]
auto num = std::uniform_int_distribution<int>{1, 11}(g);

Shit version:

// Seed provider
std::random_device rd;

// Set a sane seed
std::srand(rd());

// Generate number in range [1, 11]
auto num = (std::rand() % 11) + 1;

As you can see, the only difference between the code is the generation of the number. The seed provider and seeding the generator are an independent issue.

Now, are you really going to argue that

auto num = (std::rand() % 11) + 1;

is more readable than

auto num = std::uniform_int_distribution<int>{1, 11}(g);

?

Because it isn't.
The only positive thing about the first snippet is that it is terse - but guess what... we can solve that.

auto rnd_int = [&g](auto a, auto b){ return std::uniform_int_distribution<int>{a, b}(g); };
auto num = rnd_int(1, 11);

Look at that again.

// Deprecated, unsafe, error-prone:
auto num = (std::rand() % 11) + 1;

// Modern, safe:
auto num = rnd_int(1, 11);

Well, his rand() example is objectively simpler and easier to digest for a novice than the "correct" way to do that. I put correct in apostrophes because it's all up to what the random number is used for. I doubt that for a "guess tha numbah :v:" you need anything more than that. The important thing is that he knows that this implementation has its faults and should not always be used. From there on, it's his choice.
As for readability, it's subjective as well, based on previous experiences with other languages and/or tools. It is intuitive only if you already used it or something similar to it. You can't say whether it's readable or not without being biased.
Unless it's perl.
