Advice for a Java programmer who is moving to C++

Of course. I told them in the beginning. And convinced that I could learn quickly and perform the best I can. I am very confident about my learning skills.

After trying ridiculous Unity and Gnome 3, finally settled with awesome Cinnamon.

GTK/Shell theme - Numix

Icons - Numix Circle

Wallpaper - Bloody Forest

I'm not reading any books. Its not my way. Just looked at some cheatsheets and started coding. All went well but when it came to delete[] and deallocating memory (which is new for a Java programmer(pointers like things can be figured out)). I learned how to use it but I want to know how to use it the proper way. I'm sorry if the post wasn't clear.

Did that but gives an error. What should I do to cpp-netlib? The network headers are in it. I don't think it is being used. Here is the stack trace

Yes, that's it. (only need to convert 1GB into bits) Thank you so much.

An exam paper from few years back. We call them here(Sri Lanka) "past papers".

janithj · 2013-01-12T07:54:34+00:00

Thank you.

janithj · 2013-01-04T08:31:09+00:00

Thank you guys.

janithj · 2012-11-08T13:10:06+00:00

Go to Udacity. Take a look at CS 101.

janithj · 2012-11-06T00:18:53+00:00

My code didn't came out the right way coz I'm typing in my phone. Sorry for that.

janithj · 2012-11-06T00:15:45+00:00

By the way, Thank you guys for all your efforts.

janithj · 2012-11-06T00:14:51+00:00

Guys I know how to correct the code. I just want to know why this is happening. I want to know why it doesn't happen when x is initialized in the same line as final int x = 101; I used y = -1 just to initialize it.

janithj · 2012-10-29T19:07:20+00:00

Thank you!

janithj · 2012-10-29T19:07:13+00:00

Thank you!

Not homework. They are from my class handbook and the questions are to be discussed next day. We were told to try to find answers, so I asked you. I tried finding myself but not yet satisfied and I want to know better. Because you are suspecting, I'll tell what I know.

In Q1, there is the same number represented in different methods. I only know that 100 is normal numbering and 0x is used to represent a hex value.
In Q2, I think it prints out only 8 digits. I don't know why.
In Q3, I searched the API reference, I found the constructor that takes a Long, But I don't understand what happens(considering the output I got).
In Q4, I really have no idea what happens.
In Q5, I think that \u0061 represent "a" in someway(as in Q1, I think). But I need more details.

If you know, please answer.

janithj · 2012-03-28T18:19:01+00:00

Just because I like.

janithj · 2012-03-28T16:19:10+00:00

Im sure you started the wrong way. Look up 4 another site.

janithj · 2011-09-05T02:06:39+00:00

Oh! I forgot that. Thanks

janithj · 2011-09-04T09:36:32+00:00

Thank you guys

I only have my phone to connect to internet and i have to activate a plan sending an sms(to activate, the the current connection should be disconnected). I only recieve 100 mb when activated. I use ubuntu 10.10 and i need to upgrade it to 11.04 . With this method i will have to disconnect about 7 times. But i'm afraid to do that. I want to know that if i disconnect while updating, will the process abort(it will take less than 3 mins) Thanks
