c++ in highschool

[computeruler]

i am going into 9th grade and I want to know if that class would be too hard?  Is c++ very hard?  I dont know wether c++1 and 2 would be too much for 9th grade?  Thanks

[BC_Programmer]

if their offering it for your grade they probably aren't going to do anything beyond your abilities.

For example, I doubt on the first day they'll give you a C manual, a linux manual, a linux distribution that doesn't match that manual with a version of GCC that doesn't match the one described in the manual, and a computer that barely runs it all, and ask:

"Alright, create a tree-based implementation of Evaluating String expressions. you have 20 minutes. GO!"

basically- it boils down to wether you meet all the prerequisites of the class- as an example, is there a plain C class available? if so go for that. Otherwise they are likely catering the class to allow for those that are unfamilar with the material.

should i take c++ 1 and 2 in 9th grade? Or do 1in 9th and 2 in 10th?  I want to do that but my parents wont let me and its making me mad because I want to do someting else becideds c++ 1 and 2

[BC_Programmer]

why are they making you do both

[Ashutosh32]

I don't know what is C++ 1 & 2 but C++ is not as hard as it seems. Once you understand the basic concept, its just as simple as English.

So to start you off:

Code: [Select]

#include <iostream>

using namespace std;

int main(void)
{
     cout << "Hello World" << endl;

     return 0;
}
LOL

[BC_Programmer]

Code: [Select]

#include "stdafx.h"
#include "windows.h"
#include "iostream.h"
#import "G:\vbproj\vb\graph\dll\functionparser\release\baseparser.dll" raw_interfaces_only

int main(int argc, char* argv[])
{
   
   

    CoInitialize(NULL);
   
   
    BASeParser::_CparserPtr parseruse = NULL;
  HRESULT hr =
     CoCreateInstance( __uuidof(__CParser),
                      NULL,
                      CLSCTX_INPROC_SERVER,
                      __uuidof(__CParser),
                     (void**) &parseruse
                     );
 
  parseruse->put_Expression((BSTR)"sqr(2)^3");
  VARIANT* retval;
  retval=new VARIANT;
 
  parseruse->Execute(retval);
  cout<<retval->dblVal;
  CoUninitialize();




//__Cparser* useparse;
    //useparse = new __CParser();
   
return 0;
}


That's much simpler, LOL. my C++ program accessing my VB6 ActiveX Dll.

Ok I am only taking one c++ class now

[Ironman]

When I was in Highschool they had Computer Programming Honors which I took sophmore year and junior year I took AP Computer Science. we mostly learned Java, but we did some case studies in C++.

BC Programmer:
Is that an introduction program?? 

If so then we would have very less C++ programmers!

goodness no! actually... it doesn't even really work, since I couldn't be bothered to learn how to use a VARIANT in C++. So if the expression ends up returning a string or object it causes a page fault. Oh well.

As confusing as that may look, I have VB6 code that looks even worse...

-reduced in size to keep from taking up the whole page. the project that this is in clocks in at 15,000 lines, but I'm pretty sure there's a bit of dead-code in there somewhere.


Ahem... anyway...


As long as you stay away from COM, C++ is really no trouble at all. It's when you start doing gross stuff like my silly little sample that it get's tricky. In fact, I gave up on that one ages ago- I found it easier to find out how to make a console program in VB6...

[computeruler]

i just found my vb book. 

[ultimatum]

Take only one class, they'll teach you the basics starting from scratch. Because you're in grade nine they know there is no prerequisites to take before that, so you'll start with the basics. You're lucky you have C++ class in your high school, I only had Pascal and Java which became available a little bit to late for me.

[Bones92]

You're lucky to have any programming courses in your school. We don't have any - I have had to self-teach myself since i was seven. Useless northland schools...

[BC_Programmer]

my school had "Information technology" for grades 10,11, and 12- (11 and twelve were mostly in Visual Basic, with some Flash thrown in for good measure), as well as AP CS 12, which I myself took in grade 11, and did nothing at all in and got 100%. Actually, come to think of it, I didn't do anything in any of those computer courses after the first day or so of IT11... technically I was silently upgraded to IT12 and even then I was far better at VB then anybody else in the school of 1400.

I credit all this to my 386 and VB2 during summer holidays one year...


Now the poor bastards there are using VS .NET... I actually visited there once, and I had to supress sarcastic laughter when they asked wether I used VB .NET.

"As my main language. I find the .NET framework clunky and an unnecessary distributable, and the CLR to be a cheap copy of the Java VM. I prefer VB Classic. yourself?"

That person spent the rest of that period trying to think of something that .NET could do that I not only couldn't do in VB6 but also hadn't done - didn't go over in his favour...
