c++ - Is using *this a good idea? -

-

I'm not sure 

  return * this

Is there a way we can return an example of a member who calls the party's function? I said that the reason is that our instructor told us to avoid using pointers if necessary and I am thinking that this is a case where this indicator is returning the only way to do it.

I am working with a fractional class which keeps personal data member portions and divisor. For example, I'm talking about member function, for example, to add two degrees: 

  fraction C = apples (b);

Plus member function is defined as: 

  fraction & amp; Plus (const fracture fract)

The instructor wants us to C = A + = B, so I think this is the reason.

Get a new trainer It seems that the plus () announcement is completely false

  • Should return a price instead of context reference
  • If it has to return a reference, then it should return a reference reference
  • Should take a const reference as a parameter

    • This member can be more likely to have a smarter sense of function The Anwyn Of course, it should probably be a friend.

    -
    After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

    Visual Studio 2005: How to speed up builds when a VSMDI is open? -

    -
    Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

    booting ubuntu from usb using virtualbox -

    I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
