[QUOTE=hermann87;1116717]The problem here is that although I manage to rename the file name from "unsaved.txt" to whatever the user enters, the global char* variable ([B]fileName[/B]) won't change and remain "unsaved.txt" so the next time I try to write something new into this file it will still create a new "unsaved.txt". …

If you are having trouble with step 2, you should not have any code for step 3 and beyond. Edit out all the stuff you cannot test without step 2 being finished. Then perfect step 2. Add step 3 and make sure it works. Then start adding step 4, a …

For example, your wrapper could keep track of all the memory allocated and deallocated. This would help you make sure you aren't attempting to deallocate twice, or not deallocating at all.

Because in the first case, the pointer [B]p[/B] is pointing nowhere. You defined the pointer, but never pointed it to space for the data. In the second, you allocated data space, and the address was placed into the pointer. But the only reason it didn't segfault is luck. The space …

My initial reaction is it needs whitespace. 1) Indent 3-4 spaces, not 1 2) More spaces on a line [iCODE]for (int j = 0; j < dim2; j++)[/iCODE] [iCODE]c.mat[i][j] += this->mat[i][k] * x.mat[k][j];[/iCODE] 3) Blank lines between logical sections Makes the program more readable.

Recommendation--- Start over. Write the input function. Test it. Write the display function. Test it. you can copy the code from the current code to make it faster, but from now on *never* write the entire project without compiling and testing often. Write it in segments.

Depends on what you're trying to do. With all the '[B]#[/B]' signs and no formatting, the code is too hard to follow without some explanation.

IMAO spoonfeeding should be an offense. But the Rules as written allow it. This has been discussed before and while spoonfeeding was not encouraged, what could we really do about it? Infracting is too harsh but that's the only 'punishment' we have.

In [ICODE]cCourselist::Load()[/ICODE], why are you passing in [ICODE]Infile[/ICODE]? If you aren't using it anywhere else, just define it locally where you need it. Same with [ICODE]Outfile[/ICODE].

No, what the problem is your understanding of numbers. 10.1 is identical to 10.10 is identical to 10.1000000 Each is 10 and [B]1[/B] tenth. It doesn't matter how many zeros you add. Therefore, 10.5 (10 and [B]5[/B] tenths) > 10.10000000

With what? You gave us nothing to help with. Did you forget to read the Rules and the sticky posts at the beginning of the forum?

You do not want your variable to be [ICODE]static[/ICODE]. Set [ICODE]lowest_int[/ICODE] to the first value in the parameter list, then check all the others.

Your program tried to access outside the bounds of your variables -- for example trying to access [ICODE]var[20][/ICODE] when the definition is [ICODE]int var[10];[/ICODE]
