Third Program, three files, two are headers and one is main. Objective is to create an object that uses class Point to create a line. Here is class point: // point.h #ifndef POINT_H #define POINT_H #include <iostream.h> // Point class declaration. class Point { &nbsp &nbsp &nbsp &nbsp private: &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp int _x, _y;

&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp _y = y; &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp } &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp ~Point() {} &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp void setPoint(int x,int y) {_x = x;

I just got it all figured out. I guess taking my glasses off and looking at a blur workes cause I got it working. Since I got a thread here anyways, how about I pop a question. What would prevent the copying of one hard drive to another on one system? My Dad got his 20gig hard drive back after sending it in cause it was not working right, and when he copies his current HD over to it, it does not copy it all so it will not boot off the 20gig HD.

dunno... maybe if you wanna boot off of it you have to copy the image and not just the files that windows sees... shrug... I have no clue BC I've never had more than 1 HD in my comp <img src=http://www.ezboard.com/images/emoticons/frown.gif ALT=":("> COLORS!

Make sure you FDisk it to create the partition first. Then Format it. I STRONGLY recommend Symantec Ghost. You don't have to fdisk or format then. You just put the two drives in a system. Boot up with a system disk, then run Ghost. It will copy and create the mirror image on any size drive. <img src=http://www.ezboard.com/images/emoticons/smile.gif ALT=":)"> <table border="0"><tr><td><embed align="left" src="http://www.thzclan.com/avatars/ezice.swf" menu="false" quality="high" bgcolor="#000000" width="217" height="166" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/shockwave/dow ... <td><table border="0" style='Filter: Shadow(Color=#BB1403,Direction=255)'><tr><td>XMEN Iceman [DTM] Founder and Leader of the Base Tribes XMEN Clan Proud member of the Dragon Talon Mercenaries teamplayers Guild Member of THZ - The Hounds of Zeus clan "You weren't much of a challenge" - T2 bot after killing Iceman - click on avatar for links - no, not sausage links!</td></tr></table></td></tr></table>

Yeah, you can't just copy the files and expect it to boot. The new drive needs to have an active, bootable partition, first of all, which you have to do with FDISK outside of windows. Then it has to be formatted, and certain system files have to be placed into exact physical locations on the disk, which you normally do with the "format /s d:" command or the "system d:" command. (assuming d: is the new drive) After all of that, the windows operating system needs to be installed, but that CAN actually be copied over with everything else assuming that just the hard drive is changing and not any other hardware. <img src="http://www.xmenclan.org/xmengambit.gif"/> XMEN member Card-carrying DTM OKL Fish-napper Though a program be but three lines long, someday it will have to be maintained.
