have to learn this stuff...

ok, so in my search for a new job, I'm finding that almost everyone is asking for someone that knows C++. That's fine, problem is, I DON'T KNOW ANY.

I know loads of C and have even taken 2 classes strictly on it. I just never had the need to dive into C++. So i guess my main question is how different are they?

And can someone give me a sample program (somewhat complex) so that I can at least start looking at some code?

C++ is object-oriented programming. that is the main difference. once you get the hang of OOP, then you should be fine. as for code, you could just click on a few threads and look through the code. but do remember, things do need debugging.

edit: Also, classes are used in C++ to create new classes (lack of a better word). ex.

Code:

Class object;

object.doSomething();

that would be an example of creating an object of a Class that is not a built in type.

Structs in C++ are used similarly as classes, and are different than those used in C. Structs differ with classes only in that structs default to public and classes default to private.

I hope this helps some.

It can be downloaded from the net in PDF or HTML form. Its real good.. and must help you to migrate smoothly from C to C++

Book "Thinking In C++" by Bruce Eckel

thanks for the advice.

Alpha, so with classes... that's similar to Java classes? And i know I need to brush up on my OOP. I've been a VB programmer for the past year or so for my company and used little C, but have plenty of C knowledge from my undergrad work which I'm finishing up this spring.

I don't know if c++ are similar to java classes, i haven't learned java yet. I also recommend Bruce Eckel's book.

Hi,

F.Y.I Java and C++ classes are quite similar with some exceptions:

- functions don't need to be prototyped in java

- java has 'automatic garbage collection', this means when we create a new object we don't need to call a ~destructor to free the memory occupied by the object, it is done automatically by the compiler. It does offer a finalize keyword which can be used like a destructor, but thats another ball game

- everything written in java must be encapsulated within {} preceeded by the name of the class



e.g:

class myclass
{
public static void main (String args[])
{

}


void myfunction(void)
{

}

}//end class myclass

There are 2 versions of that book. The first one that is "out of print" and then Introduction to Standard C++ 2nd Edition. Which one?

excellent This might not be as hard of a switch as I thought.

Ober, it is entirely possible(and frequent) for people to code in C++ without using OOP. If those employers just want you to know <iostream> and little stuff like that, you could get all of that down in a day or two. However, OOP is a whole different way of thinking about a problem. Fortunately, a good number of C++ books are written specifically for people who already know C. I also recomend Bruce Eckel's Thinking in C++. He assumes that the reader already knows some C or C++, but not OOP. I wish you luck learning OOP and with your job search

ahhh!! Didn't anyone see my post? I said there were 2 versions of that book! Can you please tell me which one you all read?

but thanks for the advice. I've done some OOP with Java and I have a decent understanding of it... I just don't know some of the syntax of C++ and I'd like to get a better grasp of C++ OOP.

this site right here explains C++ basics pretty well. Also, you can try www.cplusplus.com

I've only read one programming book, and it was just an old C game programming book, came out b4 C++ got popular. The only thing I really learned from it was how to optimise stuff. I learned everything else by myself, with a little help of the internet.

Just as they said, you don't need OOP to use C++. In fact, I used C++ for 6 months b4 I even made my first class.

> Just as they said, you don't need OOP to use C++.

What's the point of using C++ if you're not doing OOP? Why not just use C in that case?

That's what I was thinking. I thought the whole purpose of C++ was to use OOP.

So did I; but there's many too many people out there who claim they know C++ by including iostream in their C program.

After you've got the basics down... I seriously suggest you pick up "Effective C++" by Scott Meyers... it's the most amazing book i've read to date. There's also "More effective C++" and "Effective STL"

Can someone answer this question please?!
