i went thro a few some days ago,
i got to nexe.gamedev.net
those are good tutorials for 3d,
but the i/o tutorials are a bit ehm well "undressed" they contain minimized information so you can do the most little..

you see?
so thats why i asked

sorry
tanks for the link!

i will get far with the vector + i/o info!!
till next time...

Jan

heh. sorry.

these are also a good set of links:
click here

the first one is particularly good and contains a full example of reading a text file line by line. it''s what i used to get going on File I/O. the rest of the links on that goole page range from somewhat to not at all helpful. they contain some filler info that supports what the first link contains

-me

ok so i tried the vector function
it works all fine,
accept for the resize function :/

i have been sitting on it the whole day but i can''t figure it out,

when i do this (i.e.):
struct Point
{
int x,y,z;
};

int i;
Point Points;
main()
for(i=0;i<5;i++){
Points.resize(i);
Points.x = i;
Points.y = i;<br>Points.z = i;<br>}<br><br>it produces an error(Tho winxp doesn''t show me which :/)<br><br>well thanks if you still wanna help,<br><br>Greetz<br><br>Fluid FX<br><br> </i>

Ermm, that code is nonsense. You make one point and then try call resize() on it and index it as an array. And I see no declaration of a vector anywhere. I think you posted something wrong.

BTW, vector is not a function, it is a template.

sorry
Point Points should be:

vector Points;
it was about the code i wrote but the real one is to big,
also it has the #include files and stuff...

only the resize doesn''t work :''(

Simple Example


#include <iostream>
#include <vector>
.
.
.

typedef struct _POINT {
int x;
int y;
int z;
} POINT;

typedef std::vector POINTS;

.
.
.

POINTS vctPoints;

// Insert Example
for ( int i = 0; i < 5; i++ )
{
POINT Point;

Point.x = i;
Point.y = i;
Point.z = 1;

vctPoints.push_back(Point);
}

.
.
.

// Retrieving Elements from the Vector
POINTS::iterator it = vctPoints.begin();

while( it != vctPoints.end() )
{
std::cout
<< "X=" << (*it).x
<< ", Y=" << (*it).y
<< ", Z=" << (*it).z
<< std::endl;

it++;
}



If you know exactly how many items you will be storing you can
call vctPoints.reserve(SomeValue)

In your example, you do not need to resize the vector every time you insert a new item.
