C++

[Kaotic Soul]

Learning C++ is difficult but I shall never give up...practice make perfect I always say.

[Sera]

so your really persistent?
good luck to you anyway.

[Nezzar]

Err...yeah.

[Vahid]

hard? heh, if you took at least algerbra 1-2 in school, its pretty easy, caue its really just knowing your math

[RZetlin]

What kind of problems are you having with? Objects? Pointers? Overloading?

[cabal]

It's really hard when the misfits in the class the year before you fooled around and got 2's on the AP Test which in turn caused the already evil and insane teacher to make the class even harder and more fast-paced. The fact that there are stuck up, ass-kissing geniuses in the class that get the most difficult projects done in one day and are there to make everyone else look bad doesn't help, either. x_x Heh, sorry for the rant. Some stuff in C++ is hard, like recursion. Right now I just wanna get through the class with a B, hehe.

I'm almost against people learning C++ first. The main reason being that when a newbie makes a "hello world" program, they look at you and the face and say, "So what?" It's better to learn something that has a GUI interface. Something easy, but that still has all the math (like Visual Basic). Once you get interested and you feel comfortable programming, then go on to C++. Even though your first C++ programs won't have any GUI or drawings, it makes the learning process more bearable, graphics-wise.

I learned C++ first, and I really have no problems with it. When I started wanting to learn graphics, I bought a programming book and learned it myself. I'll be doing 3D graphics next semester in school, and then I can show something to the Visual Basic people about graphics.

Yes, recursion can be very trickly.

Recursion is usually saved for the last lessons in class.

Is your teacher making you do an assignment with recursion?

[Ninjaa]

Heh. Recursion was one of the first things we were taught. We needed it for sorting algorithms, and binary trees, which we covered later in the year.

I don't think recursion by itself is tricky. In fact, some problems can best be solved by recursion - without it, you would have to do a lot of work to get the same result. Unfortunately, most problems best solved with recursion are rather complex by their nature; so while it looks like recursion is difficult, in reality it is used to solve difficult problems. I'll give you an example:
Try to write a parser that calulates terms like "3*(1+2)+((2*2)+1)" (output is 14). (Programming languages with an "eval" function that does the job for you are not permitted ;-) Such stuff is best made with recursion.

[Mohd]

recursion hehe . . .
All you need in recursion is to practice by solving alot of problem.

>>ammoQ: In fact, some problems can best be solved by recursion - without it, you would have to do a lot of work to get the same result.

yeah like fibonacci series if you make it using iteration (for,while) it will be too long but with recursion only 4 lines

long fib( long n )
{
if ( n == 0 || n ==1)
   return n;
return fib( n - 1 ) + fib( n - 2 );
}

[Ninjaa]

Heh. That was our first example of recursion in our class this year.

I wondered what it would look like without recursion, so I programmed it in BASIC on my calculator. It's 13 lines as it stands.

[Mohd]

This was my second example Nina the first one was factorial. I remmber I got a question in quiz about recursion:

Show the output (hey not using computer, brain of course)

they gave us a three nested for loop with pointer which point to two d array in recursion after that quiz I got

[Ninjaa]

Heh. I got a nasty recursive program that I had to trace on my midterm as well. I had 5 minutes to solve it. I figured it out right as the teacher said the time was up. I quickly wrote it down and handed it in. I was one scared mother...

[ammoQ]

It might be of interest for some of you that in computer science (e.g. theory of complexity), everything is described as a recursion - there is no such concept as a loop.

[cabal]

I'm glad my school requires VB before C++. In VB we learned all of the concepts without going too much in depth (ex. Binary Trees only as opposed to Binary Trees and Expression Trees, less sorting and searching algorithms). This year we need practically an entire semester for the AP Case Study, so we had to quickly learn how everything we knew last year was implemented in C++. If we went in there the first day and didn't know anything about arrays or variables we simply wouldn't be able to prepare for the AP Exam and its case study. Plus, VB doesn't have pointers.

Heh, recursion hurts my brain. x_x We also had to program Fibinacci and factorials recursively.. not to mention that evil, pointless peg game.. -_-. Hehe everytime we have a recursion assignment someone yells "FIBINACHI!!!" real loud Right now my teacher is making us do a Binary Tree class. In fact it's due tomorrow and I only have about ten percent done. :x

That theory of complexity sounds terrible. I dunno, maybe later in college I'll like recursion, but right now it's too wacky.

Um im new and need to learn fast i am in a group called STLP and we have a presnitation and have to show sum thing new like c++ and all i know is } and that is it plz help!!!!

[Ninjaa]

I suggest you buy a book and start learning then.

[Drake Dagow]

well i did the 15 hour crash course 1 and it said sumthing abou c++ soft war what is sumthing awsome but simple


sry but im in a hurry
