Hi guys,

I have to learn some C# and .NET, are there any reference books? Also, is it possible and reliable to program C# and VB.NET in Linux? I'm trying to avoid installing Windows just for C#.
...

This should be fun. I'm interested.

I'm curious to know if everyone is working on some other projects besides the normal work.

This might help.

char is one byte, so it cannot have the value of 280. The compiler should have complained with a warning.

Anyway, it goes to 24, because 280 is 100011000 now truncating this to one byte we have...

You're missing the break after each case.


switch(c){
printf("Start\t");
case 280:printf("David Beckham\t");
break;
case 24:...

fp=fopen("data.bin", "rb");

rb means open file for reading but you want to write to it, so...

Oh, yeah I missed that. If I understood your logic correctly if a cell group exists you're loading from a file else you just initialize everything in new_game.

When does your issue happens? When...

Where is the constructor? You're not initializing cell_energy, nor any of the other variables. They will take what happens to be in memory.

As far as I understand you're trying to insert a pair of type <int, string> and it works fine for the first call of ShowMeMap but the second call expects <int, list<string> > however you're still...

Thanks! I got it now.

Hi all, the code below doesn't do what I would expect and I'm having some problems understanding why. I was expecting to see "Bar method" as output however it gives "Foo method", also if I use a...

Thanks for the replies guys. What I don't understand is the relation from the conversion in wikipedia and the ones in the book, because in the latter they make reference to object-to-inertial and...

In 3d math primer they have two ways of converting euler angles to a quaternion, depending if we want a inertial-to-object or object-to-inertial quaternion. However in wikipedia they use a different...

What I would like is to rotate the cube[around its center] and not the world axis.

I'm building a cube using other smaller cubes and its being constructed like this:

a = world axis
c = cube

a c c
c c c
c c c

Now I would like to move the axis to the center like...

Oh I see, the forward declaration allows Foo to use pointer or references to Bar but it doesn't allow any use of the Bar class members because they haven't been defined yet.

Edit: I hadn't seen...

class Bar;

class Foo
{
public:
Foo() { p_Bar = NULL;}
~Foo() {}

void setBar(Bar *b) { p_Bar = b;}
void doSomething()

Ooh. How didn't I think of that. Maybe its time for a break. Thank you laserlight.

Hi all,

Is there a better way of copying the lines of 4 two dimension vectors?

The idea is to copy the contents of line X from v1 to v2, v2 to v3, v3 to v4 and v4 to v1.

I'm using to two...

Well, thanks for the replies whiteflags and laserlight. Regarding the question maybe I didn't understand it correctly, because I can't find any answer/hints to it.

Most of what you said I already know, but I was asked that question and couldn't really find a case and still can't. Maybe it was a trick question.

Hi all,

In which cases does the compiler forces us to have a copy constructor and an assignment operator? I mean, when we have to define both explicitly.

Thanks in advance

Is there a performance penalty if I do function prototyping for non-member functions?




( code above, classes, etc )

// Some comments
void
Foo(int &v); // declare

Yes, you're correct, it should be passed by reference to avoid unnecessary copying.

I will look into std::transform, thanks!
