My schoolwork got rejected...
« on: May 17, 2010, 04:08:13 pm »
My schoolwork got rejected because it was too complex for my teacher to grade.  I think my Axe and Asm knowledge rubbed off, making my C++ a lot more optimized.  My teacher took one look at it, shook his head, and told me that he wouldn't grade anything that complex.  For those who know C++, you make the call.

My awesome version:
Code: [Select]
#include<fstream.h>
#include<iostream.h>

void main()
{
char string[25], header[50] = "Name     \0Address  \0City     \0State    \0ZIP Code ";
ifstream file_ptr;

int offset = 0;
file_ptr.open("ADDRFILE.DAT",ios::in);
if (file_ptr)
{
do
{
file_ptr.get(string, 25);
file_ptr.ignore(80, '\n');
if (!file_ptr.eof())
cout << header + 10 * offset << ':' << string << '\n';
offset = (offset + 1) % 5;
}
while (!file_ptr.eof());


file_ptr.close();
}
else
cout << "An Error occured!\n";
}

The version I had to turn in:
Code: [Select]
#include<fstream.h>
#include<iostream.h>

void main()
{
char name[25], address[25], city[25], state[25], zip[25];
ifstream file_ptr;

file_ptr.open("ADDRFILE.DAT",ios::in);
if (file_ptr)
{
do
{
file_ptr.get(name, 25);
file_ptr.ignore(80, '\n');
file_ptr.get(address, 25);
file_ptr.ignore(80, '\n');
file_ptr.get(city, 25);
file_ptr.ignore(80, '\n');
file_ptr.get(state, 25);
file_ptr.ignore(80, '\n');
file_ptr.get(zip, 25);
file_ptr.ignore(80, '\n');
if (!file_ptr.eof())
{
cout << "Name: " << name << '\n';
cout << "Address: " << address << '\n';
cout << "City: " << city << '\n';
cout << "State: " << state << '\n';
cout << "ZIP Code: " << zip << '\n';
}
}
while (!file_ptr.eof());


file_ptr.close();
}
else
cout << "An Error occured!\n";
}

Is there a version that's even more optimized?  Feel free to rewrite it if you want... ;D

Interesting. Assembly power, ftw.

The first code looks much better (smaller, less repetitive, flexible to changes) to me even if I don't know what those C++ functions are doing exactly.

Wow, that is really annoying when teachers do that :( Sorry you had to downgrade your project.

Nah, it's fine, as it only took me 10 more minutes. ;D

Sigh... If the teacher can't understand something you can, he ought to learn how your code works...

I agree with that. Or that you should teach the class for the day and get the money he would've made :P

Haha well its still harder to think in unoptimized thoughts once you are good at not doing it :P

he should have given you full marks if it surpassed his level...after all that is then past the level of the course isn't it?

Lol, that is both a win on your part and a fail on his part :P he should have given you full marks, or maybe *tried* to decipher it! ;D

lol epic fail on your teacher's part :D

The disturbing thing is... what part was too complex for him?  The only real differences are the two lines
Code: [Select]
cout << header + 10 * offset << ':' << string << '\n';
offset = (offset + 1) % 5;
The first is fairly straight forward (display "{something}: {what you retrieved}"), and the second is just making "offset" go 0-1-2-3-4-0-1-2-3-4...

[edit] Now that I think about it, for my mathematical software survey ("SoftSurv" for short :)) final project my code had a lot of tricks like that.  I wonder if that's why I got an A in the class (my code was completel crap lol)

That code isn't hard to follow at all, and its not very complex.  But I have a feeling what your teacher is complaining about is that you made it very "C style" instead of "C++ style".  They want to train you to stick with the C++ commands and not do those efficient workarounds becasue eventually you're going to be dealing with abstract objects and your code will no longer be portable when instead of strings you have classes and instead of characters you have child objects.

Okay, that's probably why he did it.  He likes to have us program certain exercises in a certain way because it'll help us later on.  Thanks for the info! :D

Wow that was retarded from the teacher, but again maybe Quibigo has a point. Still, I would hate if I worked hard on a school project and it got rejected because it surpasses the teacher requirements way too much.

In my case, the worst I had happen is that the teacher and other students couldn't help me fixing bugs in my last project before graduation (The Reign of Legends 0). It was too advanced for him so I was pretty much on my own x.x

I don't have much experience with C++, but Quigbo does raise a very good point. Nice insight there! You should also remember that many teachers just know how to grade things based on how the course is laid out, IE they only have knowledge of/ teach what is outlined in the course, and may not have (much) experience on the subject outside of that, especially on the high-school level. It's unfortunate, but that is the way our public education system is in the U.S.
