Yeah, I know. That's one of the changes I'm wanting to implement. I don't think there's a single instance of the word "const" in this entire code. I was a naive young coder once :)

I've removed the top seven lines from both files as that contains identifying information :)

AmVector2.h:


#ifndef _AM_VECTOR_2_H
#define _AM_VECTOR_2_H

Just porting a small project of mine from Windows to Mac and I've hit a compile issue I'm a bit confused about.

I used CMake to build an XCode project and when I try and compile my maths library...

Yeah, I know what you mean. I undertsand it's a bad idea. It's just something about C++ I was unclear on.

I missed the dereference on the this pointer :rolleyes:

Oops. So I did :)

So, would...



class MyClass
{
MyClass()
{

Not according to the C++ FAQ Lite. See here: "Instead it calls Foo::Foo(char,int) to initialize a temporary, local object (not this), then it immediately destructs that temporary when control flows...

The example I gave was a bad one in that the function I'm using already has a return value so I have to pass in either a reference or pointer.

What I don't understand is how come it's valid to...

I should probably know this, but I don't so I'm hoping someone can fill me in.

If I create an object using the default constructor, then pass that object via reference into a function whereon it...

I'm asking what I could be missing from my interpretation of the bitmap file format. I've followed the documents I could find on the Internet and I appear to be following them to the T but I'm...

Yeah, that's what I'm already doing as I mentioned in the original post :)

Really? I haven't read that anywhere.

So, currently the data block in my image is 17 (+1) x 9 pixels which makes it 162 pixels. Does this mean I could get away with just modding 162 by four and...

I'm not sure if this is the right place to ask this but I couldn't think of anywhere else.

I'm writing an app where I'm wanting to convert raw byte data into bitmaps. I did a bit of reading about...

Ah, right. I seem to remember reading something about this a while ago. Isn't there some kind of pragma directive I can add to stop it from doing this?

I've created the following struct...



typedef struct {
short type;
int fileSize;
short res0;
short res1;
int dataOffset;

Yeah, I get that. b doesn't actually contain a value. It contains the address of a. So when I increment the value stored in the memory address that b point to I am incrementing the value of a by...

Ah, I think I understand but I just want someone to confirm it.

If in my main function I do this:



int a = 100;
int *b = &a;

*b += 50;

Ok. I'm a little confused about pointers then. I understand references now but take the following code:



void inc(int *val)
{
*val++;
}

int main()

I think that's a little subjective. Even so, I AM using references. See: swapInts(&firstInt, &secondInt);



A thought a reference was literally the address of the variable? So it essentially...

You're right. It was swapInts(&firstInt, &secondInt);



If that's the case then why does it work in the function? If I do...

int firstInt = 1;
int secondInt = 2;

...and say the address'...

I have to write a function that will swap the value of two integers around. The definition for the function is swapInts(int *firstInt, int *secondInt);

As it's address' that's being passed in I...

Does anyone know if it's possible to count the number of digits in an integer? One of my friends recommended log10 or something but I can't figure it out.
