If you were a digit of pi...

[Eris]

O_O you win haha. I have to agree with you on that one. I forget all about behind the scenes in the world of assembly and below. I have only done a small amount of assembly in my time and that was limited to some debugging but I do enjoy programming and such. I'll have a look into that link on virtual memory. That leaves me with another question. Where are pointers stored anyway? The heap? And are not ALL pointers stored in that area of memory?

Pointers are stored the way any other variables are stored. If they are local variables of a function, they are stored on the call stack. If they are dynamically allocated, they are stored on the heap. If they are global variables, they are stored in the data segment. They can also point to any of these memory areas.

Well yes ofcourse that makes sense. I was beginning to think I had read something wrong in the past. You a Computer Science major too?

[Capernicus]

Dude, srs, threadjacking.

So would this be a good example?

void *ptr;
int num=1;

ptr=(void*)num;

cout<<*(ptr)<<endl;

[Takizawa]

I'll pick the 3 because I'd be leading the way

[Mmmmmmmmmm]

I would be the 1 because that number is just sexy. Standing there all upright and strong. Now that is a damn sexy number i would get with any day!

One is the loneliest number, though.


I'd be the 1000th nine.

I'm a physics major, but I've got 7-8 years of experience with C programming, and have amongst other things written a C compiler.

So would this be a good example?

void *ptr;
int num=1;

ptr=(void*)num;

cout<<*(ptr)<<endl;

That is not valid. You can't dereference a void pointer. If you change "void *" to "int *", it will be syntactically correct, but will likely crash when you run it, since "1" is most likely not a valid memory address.

Here's an example that will work:

int digits[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
int *p = &digits[0];
unsigned int q = (int) p;
q = q + sizeof(int);
p = (int *) q;
cout << *p << endl;

This will advance the p pointer by sizeof(int) (=4 bytes), making it refer to the second element (that is, "1"). Technically, it's better to use uintptr_t (defined in stdint.h) instead of "unsigned int", but "unsigned int" will work on most 32 bit systems.

Dude, srs, threadjacking.

Sorry about that. I'll stop now, if Shin Natsume wants more information, he can PM me or something.

[Señor Nobody]

O.o Well, I would have to be the 11th 7. Try and guess why.

Lame Joke.

[DOOM!]

Edit: Max Elite, that is such a cop out answer. Seriously, if this thread has null value then why are you posting in it?

To get his two Rupees, which is why I certainly do. There is nothing about this thread. π =Spam.

[Inferno Alchemist]

Screw a digit, I'll be the whole number.

[John Watson]

Mm...3 I guess. o.o; I just like the number 3.

[SigmaSD]

Wow these threads just get crazier and crazier don't they? Its stuff like this that drives people away. *chuckles*

Well I would be the 8 between the 4 and the 8.

[BlanketHarp]

In C++? No one uses that crap!

I use it

and i would be. . . . .9

[Diocletian]

I’d be your friend, your father, your confidant, trick! I believe the 3 because I have to start first and let the numbers track behind me.

[Eris]

I'd be the last digit of pi.

[Capernicus]

I'd be the last digit of pi.

So you don't exist?

[Ωmega]

I'd be the decimal point, because I don't have to follow your rules, MAN.

but...I wanna be the decimal point ;__;

[Eris]

So you don't exist?

Sure I exist. In base pi, I'm 1.

[Shin Natsume]

Sure I exist. In base pi, I'm 1.

Hows that 1? ((pi)^0)?

[Capernicus]

Hows that 1? ((pi)^0)?

No, not base in the sense of exponents, base in the sense of the number of digits in the positional number system. For example, our system uses base 10, and we have 10 different single characters to represent numbers: 0-9. If we were working in base pi, we would have pi number of characters. And, when we got to pi, it would need to be represented by two characters.

Though, I'm not sure Eris' joke is right. She'd need to elaborate more.

1 is the only significant digit in ... 0.001; 0.01; 0.1; 1; 10; 100; 1,000; 10,000 ... etc.
