ok lemme get this straight....
I made it as 13 because then i was about 12ish, i started to write jibberish programs which barely compiled and they were at best something like this, so i ignored that age and I said '13' because at that time, i had a solid understanding of C# and vb.net. Both of which were very easy for me. Now, 15, I know waaay more programming (C#,Vb.net, C++,C,JAVA,and the wpf version of c# and vb.net).
I mainly use the c# and vb.net most today but I have programming competitions and I need to know c++ and JAVA so i gradually developed that as well.....
And for all you 3rd grade babies out there who program...good for you and I hope you spread the knoledge learned some day to someone else
-Turns out, you will get money for this.....
