Sometimes I'm amazed at how much I completely miss when I check my code...

Thanks!

Yeah, me yet again. I tried to avoid bugging you guys, but I've hit a problem that's so puzzlingly nonsensical that I can't even begin to figure out what's going on.

Here's the relevant parts of...

Thanks!

Hi, me again!

I have this code:


char* getfilebits(char* filename)
{
char* ptr;
ifstream file (filename, ios::in|ios::binary); // open file for reading
if (file.is_open()) // did it...

I actually figured this out just now...

putting

class <classname>;

at the top of the file, works like the prototype functions in the classes. Fixes my interdependency issues.

I've got two classes: matrix, and ffbyte. They both work fine, and ffbyte is loaded as a header in matrix, which is a header in main.

The elements in the matrices are ffbytes. This works fine,...

Thanks :)

I've even got it working with vectors now. I've been able to cut out a few conditionals due to the exception throwing. Now, maybe I should try making an "invalid matrix operation"...

Hi, me again. Is there any way to change this code:


ostream& operator << (ostream& os, const matrix& m)
{
int r,c;
ostream out;
for(r=0; r<m.rows_; r++)
{
for(c=0; c<m.cols_; c++)

Yay! It works!

Okay, vectors sound important. I'll learn them, seeing as I'm making matrices with a view to implementing AES (I like to jump in head first, and explore).

I actually had a copy...

I do not have a copy constructor. The reason that I'm not using vectors is because (a) I don't know what they are, (b) I've been told this is the most efficient solution.

Right, off to write a...

Right, that makes sense. But then, why does delete [] cause a violation? It works fine when matrices are deleted at the end of main{}. I can't see why it would cause a violation just because it's...

I've defined a matrix class in C++, with a single data_[] array, and an overloaded () operator to access it. It worked fine as a container, but I defined an addition operation:


matrix...
