If you want to get into programming, you could build your own apps for Android or ios. There are plenty of free tutorials out there to get you started. This will get your feet wet in code, and maybe make some money if an app becomes popular. 
 
Coding is not the only IT Avenue. There is also the infrastructure side,setting up networks and servers. Solving business problems with technology. You can get started in this fairly easy by getting your comptia a+ certification and find a user support job. Like the geek squad. better yet, in house support for a company or a call center. Then you will start gaining experience. 
 
There is plenty of room for people with certifications. Not in programming as much. But with certs and start getting successful projects under your belt, you can go a long way. Interviewers want to hear what the problem was, what you did to resolve it and what the outcome was. Quantifying your improvements into something that is a positive outcome is huge. 
 
The business world is all about boasting your accomplishments in a professional manner in my opinion. 

Don't be a dumbass and think you will learn it over night. Its takes time. Also, YOU WILL NEVER LEARN EVERYTHING ABOUT C++ PROGRAMMING! You need to learn how to learn what you need when you need to learn it. Think Just In Time(JIT).
 
Start with the basics:

 
Spend a few months learning and writing anything you want. Have fun with it, make a simple program. Like a PC part picker calculator, something that interests you. If you like girls, do what Bill Gates did and make a app that track what girls are in what classes so you can figure out what classes to take. That is from bill gates himself in a code.org video.
 
Next, learn about a framework like:
 
http://oxygine.org
http://oxygine.org/doc/api/classes.html
 
Don't jump right into that, if you can't understand the difference between a instance variable to a class variable(just an example) you won't understand a framework. 
 
Dedicate time everyday, or most days to learning something about programming. 
 
I was in the same boat as you, I wanted to learn how to program. Now I am not an expert, I am not a CS student, but I am about to finish a intro to Java course and I am feeling confident I can run a website with Java on the Server side. After pounding Java in my head for 2 months, using youtube, the java tutorials(official and non official) and a free Java for Dummies book that is online, I feel I can make some pretty cool apps, maybe not a game, but If I wanted to I probably could.  Logic is a whole different thing from programming. 
 
The thing about programming a game is you need to make up the game logic.
If player is hit/ if player blocked/ if player is in position xyz/ if player has certain ability/ if player currenthealth - hit< 0//// That is logic, thats is were a game can becoime tricky.
 
If you dedicate yourself to learning, you can do it. Like I said, I am in a Java class, I'm 30, two kids and a wife. I am taking the class online. Before the class, I would watch a few videos, write a small console calculator and then be done. All the class did for me was get me to focus longer and had me read Oracles website on learning java.
 
So far it worked! Although this is super simple, I made a app for drunks... while drinking! http://thedami.co/TD/weather
That tells you if its the right temperature to leave your beer outside. It only works for the area I live in, but to make it local to anyone, I just need to google "how to get browser location"......... and I found it

Look at that, my app will be updateded.!!!!
 
tldr Dedicate yourself, learn the basics then search for specifics, you will not learn everything, but you can learn what you need when you need it.

I know a lot of people around here want to learn to program. Well, I wanted/still want to learn and am going to share what I have done so far....

It is not much, and honestly the code is underwhelming, BUT I made it, and I focused on Java for 2 months to make it. I will make something better, This was just a proof of concept I made for a friend. 
 
How I learned:
youtube thenewboston and mybringback java vids
The Java Tutorials from Oracle
Java for Dummies FREE ebook
Whatch JavaBrain on youtube to focus on web development with java(or you can find countless Java game tutorials)
Googleing what I wanted.
 
I spent 2 months learning java, all this work if to get a A in my Intro to Java class at the community college I am going to, but all the resources are free!!!!!!! The only thing my colege did for me was force me to study Java for 2 months so far. I am pushing hard to learn more. I am working on .jsp pages and am starting to work with some frameworks, but really all I did was spend the time doing it.
 
TL:DR focus for a few months on Java! I decreased my video game playing time down tremendously to use that time playing with Java.  

I think that AleksaNS is right. I believe that when you initialize your 'a' value Java treats it as:
double a = (double)(yks + kaks + kolm); Meaning that the summation is done as integers.
Looping 100,000,000 times is fine, but taking it up to 1,000,000,000 takes the sum over the highest limit of what Java 32 bit signed integers can store (which is 2,147,483,647) and you end with an overflow, which causes the a value to be negative.

I haven't copied your code to test this, but try casting your 'yks', 'kaks' and 'kolm' values to doubles or longs as suggested by mopman, before doing your summation.
 
quick tip edit: To get the highest value of an int, double or long, just use Integer.MAX_VALUE, Double.MAX_VALUE or Long.MAX_VALUE

There are a lot of great tutorial youtubers. MyBringBack has a good series to! I will watch a few different ones to see how it can be done in different ways.

Try the free 1 week trial at Lynda.com, just make sure you have the time in the week, then you can bang through a lot of info. I am waiting for a week to open up so I can do PHP/Web stuff. Then I am on to Java, want to write a small android app this fall.

How? Its highly unlikely his computer could play them.

Codeacademy is a great place for learning to code in Javascript/html5
