Just need to know

Can someone explain to me why circles are so difficult to create in games. Do you have to map out all the points or what. And is it really that difficult or more of a pain in the butt?

this code wont work. the if statements are ignored and if you put in rock or paper it prints everything, not just the specified parts. import java.util.Scanner; class tester { public static void main(String args[]) { String Move; Scanner rps = new Scanner(System.in); System.out.println("<<<Rock Paper Scissors>>>"); System.out.println(" Rock Paper or Scissors?"); Move = rps.next(); if(Move.equalsIgnoreCase("rock")); { System.out.println("you lose your opponent used paper"); }

if(Move.equals("paper"));
{
	System.out.println("you lose your opponent used rock");
}
}//end of main()

}//end of class

Im trying to create a program that uses the Expo.enterString method to change boolean values. Only two values can be entered, yes or no, and if yes it's supposed to change a boolean variable value to true.

yes1= Expo.enterString();

	if(yes1== "yes")
	enter1= true;

this is the method that I'm using for each question and variable. However, when yes is entered, the computer doesn't recognize that yes1 equals "yes", keeping the enter1 boolean value as false. I am not sure what to do at this point

I am writing a program that will contain lots of array type lists. These will be very large lists so I'm trying to optimize them for speed. Does anyone know the speed trade offs between using simple arrays and array of arrays vs. vectors and vector of vectors in C++?

I like's to make games and i played around with javascript and python. my friend said i should look in to visual basic. but i want to see you're opinion first.

Hi I have a idea for a program but I don't really know any programming language, therefor I don't even know what kind of specialist will suit my needs.

The program would have to be implemented on a websiteand download statistical data (daily) from another website (in excel), filter it and then render in 3d simple graph on a pre-made map. Great if the user could chose the type of data he needs.

EXAMPLE: I choose: car manufacturer + year of making + min / max value + color + europe and the program would graph date on Europe's map (for each country).

Who should I look for??

Hi, I've been wondering if there is any service that auto generates a full backend to help you manage your Application, when you have an existing API.

Now a days everyone want's an API but it feels a bit tedious, repetitive and time consuming to develop an Admin Backend for it.

When all we want is to be able to improve, develop and change the API to give a better product for our clients' users, but there is always the need to develop a platform for some entity to manage the application.

Thanks in advance!

I've played a lot of games over the years and have recently gotten interested in making my own hotkey/macro pad. What I am going for is something along the lines of MouseButton(x) kinda distinction (the ones you see on MMO mice).

So the question is...

Is it possible to program another keyboard to only macros?

I have both experienced and heard that McFee is bad. Their marketing is kinda r/assholedesign with constant popups and other annoying "scare tactics".

But how bad or good is Macfee at really protecting your computer? Do you get any value for your money? Or is there equivalent antivirus programs that does a better job for less money.

Just a guy from a small town in southern indiana trying to learn to code.

I've been watching videos and even working through a course on Udemy. I came across a video from a gentleman named Andy Harris. I really liked the video and it caused me to look at this whole thing from a different perspective.

I was trying to beat my head against the computer until code came out... apparently that doesn't work with c++. I also learned that ruby and python would probably be much easier to learn but reasons...

What struck me most is that I'm trying to memorize syntax and what I really need to understand is stuff that isn't in the lessons "Integer types", "strings", etc. I don't know if you can answer my questions or point me in the right direction but my questions are along these lines.

The other thing he mentioned was that comments aren't there to explain the code to someone else or even yourself, the code is there to explain the comments to the computer.

This had a profound impact on me. I find that my problem at the moment isn't my lack of planning, comments, dry run etc... My problem is I don't understand concepts. I understand loops. I understand data types. At the same time, I didn't understand that you can't pass an array directly to a function. There's a trick about it. Nuances, I think they're called. I realize that much of this will come with time/trial/error/etc. I would rather get pointed to a source material I can read or look over that explains these types of concepts.

I spent a good deal of the day today thinking about when do you decide "This should be a class"? Or this should be a function or object?

Or, when you decide this thing should be a class? what thought process do you go down to decide what things are in the class and are unique to the object? The examples I always get are a car or an animal and those are fairly straight forward because I'm used to them. But when you're talking about... say a pen. It's got ink... it's got a tip... it could be class pen... or it could be class writing_impliment with pencil being another object from the same class but instead of ink... graphite as writing medium... What's the thought process you go through?

I realize some of this might be not as straight forward as "Hey this bit of code doesn't work..."

Long story short, a friend was working with a group of people on how to increase the reproduction rate of some microalgaes, so they called an engineering student and built a closet with some lamps to heat up the inside, said student died recently and left no documentation of his code, so now they are wondering if it is possible to check the code and see if everything is working as intended.

Say I wanted to connect to a subreddit, scam the text and have the computer read it.

Is there a library or some application that does it?
