Programming :: C++ Operator Overloading Within Already Overloaded Operator
Apr 16, 2011I'm having a bit of an issue using overloaded operators in an already overloaded operator. In my following code, I have overloaded the && operator to compare two Course objects. The operator in turn goes to a function which calls other overloaded operators to compare private object variables of that object to compare them.

Jul 16, 2009Has anyone successfully installed Fedora Core 11 on a system with a Tyan Trinity KT-400 S2495 motherboard? I have two systems with this motherboard. I tried to install FC11 from the live CD. Both systems have AGP video cards based on the Nvidia GForce-2, although the cards are of different brands. On one system, FC11 installed, but after the machine is booted and I log-in, it runs slower and slower until it is effectively frozen after about fifteen minutes. Somtimes a "Kernel Failure" window will pop up. A momentary press of the power butting will bring up a shutdown window and shut the machine down after a wait of 60 seconds.) By doing several reboots, I did manage to update the installation. (My complements to the developers on the fact that the package download will pick up where it left off).
However it still freezes. On the other system, when the Live Cd has booted, the keyboard and mouse don't work, so I can't do the installation. I tried a different keyboard and mouse, tried rebooting several times. When I boot the machine from SystemRescueCd (kernel 2.3.29) the keyboard works in the text mode. I used the "wizard" command to try various graphical modes. In the default Xorg graphical interface, the keyboard works but the mouse doesn't. In the "Vesa" graphical interface, neither the keyboard nor the mouse work. I tried the Ubuntu 8.04 live CD and the keyboard and mouse don't work. I tried an FC 8 install Cd, the keyboard works in the installation screens but the mouse doesn't. I replaced the Nvidia AGP card with a Voodoo 3dFx PCI video card. The system won't finish posting. It hangs on the second screen. This system formerly ran Windows 2000 OK and before that it ran Window 98. But perhaps it's now defective?

Programming :: TCL AND Operator (&) On A Binary Value?
May 1, 2010I have a binary value which I receive from a controller. Say this binary value is 42. Just plain hex 42. If you would look at that byte in a debugger you would see 42.Now this value hold 8 bits each indicating a high or a low output. So 0x42 = 01000010b. Which means bits 1 and 6 are '1'.When I would want to find out which bits are set and which are not in a language like C, I simply do:
Code:
mask = 0x80;
if (binval & mask) {...}
etc..
However I am programming in TCL, and I try to do:
Code:
set mask 0x80
if { [expr ($binval & $mask) > 0] } {...}
etc...
this fails. At the moment the expr is executed, $binval is evaluated and substituted so the expression I am evaluating is
Code:
set mask 0x80
if { [expr ('B' & '0x80') > 0] } {...}
etc...
Eventually I got it working by converting the $binval into a '0x42' string value, like this:
Code:
binary scan $binval c byte
set byte [format "0x%0x" $byte]
set mask 0x80
if { [expr ($byte & $mask) > 0] } {...}
etc...[
Then the expression yields what I want. But this seems so stupid and clumsy. Isn't there a better way where I can compare two binary values without conversions?
Ubuntu :: Invalid Arithmetic Operator - Trying To Take Away Two Numbers With Decimals
Feb 7, 2011I'm trying to make a bash script that takes away two decimal numbers. This is to work out partitioning information.
Code:

trimsize="1.5"
partitionendsize=$(($hddsize - $trimsize))
I get an invalid arithmetic operator. Not sure how to minus these two numbers. Is it a floating point issue?

Programming :: Getting A Comparison Operator To Work?

Below is a small proof of concept script with the bit I'm having trouble with.

Debian Programming :: Square Bracket Operator?
Sep 1, 2014Is there a way to achieve the following with the square bracket operator?I have a class:
Code: Select allclass A

private:
int m_iCount;
ItemCollection Item_Collection;

The probelm is that I am not just blindly assigning whatever given on the right hand side to the returned value from operator [], I need to verify it's not NULL, and it is not already there in the Item_Collection, and I also need to increase the count.
Programming :: Operator For Floating Point Comparison?
May 10, 2011I know it is wrong to use the "==" operator to compare the equality of two floating point numbers. Logically it would seem that if the "==" operator is not usable for floating point comparison, then the "<=" operator would also not be usable. Is this true? The lack of google search results on this topic made me think that it must be true. If that is true, then is it true that the only way to compare floats with <= or >= is with something like the code below? Code: bool smaller_than_or_equal(float a, float b) {
if ( fabs(a-b) < EPSILON){return true;}
else if (a < b) {return true;}
else {return false;}
} I think this is a general question, but if specifics are necessary, I am using the C++ language to code at the moment.

Programming :: C++ Cin Doesn't Wait For Input By Operator
Jan 4, 2010I am trying to learn C++.I implemented a simple archive program, and I am in a situation in which the user is prompted by a menu to make a choice.So I have some cout instruction to illustrate the possible choices and then
int choice;
cin>>choice;
and everything works fine.I introduced this code in a "while" loop that checks wether the choice made by the user is valid or not:
bool check=true;
int choice;
while(check)
{
cin>>choice;
if(the choice is valid) {...;check=false}
else cout<<"please make an other choice"
}
What is happening is that if by mistake the user introduces a character in place of a number, the loop repeats indefinitely because the program, when it get to the "cin" instruction, does not pauses to wait for a new input.

Fedora :: Error: Missing Binary Operator Before Token
Oct 26, 2010I have been spending several days getting wxwidgets to work in code::blocks ide on several different platforms. Now I am down to one instance that I can't figure out. I have wxwidgets working in Fedora 13 x64, but cannot get it to work in a Fedora 13 x32 version. Actually, wxwidgets seem to be installed OK, but I run into compiler errors when I try to compile the default wxhello project. I get quite a few messages, in different header files, of this type:
/usr/include/assert.h:39:42: error: missing binary operator before token "("#if defined __cplusplus && __GNUC_PREREQ (2,95) From my friend Google this would seem to be caused by an older version of boost (before 1.37) - see http://bugs.xmms2.xmms.se/view.php?id=2215 ("It is an issue with old versions of boost and gcc4.4 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36453 It is fixed in boost 1.37")
I did a yum info command on both systems for every relevant package I could think of, including gcc(v4.4.4), gcc-c++(4.4.4), libgcc(4.4.4), libstdc++(4.4.4), boost(1.41.0), wxGTK(2.8.11), wxBase(2.8.11). Both systems are fully updated and have the same versions, with the only difference being 32 vs 64 bit. The same headers compile with no errors on the x64 system, but not x32. I have been able to find no other reason for this error than older versions of the preprocessor, yet that is apparently not the case here).

Debian Configuration :: Install A Multi-core System And Configure It To Run Several VMs, One Each For A Firewall, A Caching Proxy Server, A Mail Server, A Web Server?
Jan 25, 2011I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

Programming :: Change Or Add Paths For The Compiler To Look In When Using The "<>" Operator?
May 12, 2010My compiler won't find <new>. Since it's such a basic function, I'm a bit confused. Is <new> supposed to be in a file of its own? Where do I find it? And if it turns out to be missing on my computer, where can I find a <new> one? Or do you see anything else that I do wrong?
After some trying out, it seems I can't find stuff like iostream or any other basic stuff either. The compiler is prolly looking for them at the wrong place. Does anyone know how I change or add paths for the compiler to look in when using the "<>" operator?
