Hello Daniwebers! I was just reading This C++0x Beginner Tutorial: http://www.daniweb.com/software-development/cpp/tutorials/373787/beginning-c0x-making-a-raii-class And I was confused by something: " `int_vector(int_vector& aV);` > Obviously, this type of constructor would allow the transfer of the resource, since the source object can be modified and put into an empty-state (or "zombie-state"). But there are …

Simply compile it using any compiler, like g++

As NathanOliver stated, it's a good practice to assign 0 (NULL) to the pointer after using delete because after calling delete the memory object pointed to should no longer be used since it has been destructed and no longer belongs to your program.

Hi all! :) I'm really curious to know how fast can you type? Go here: [url]http://speedtest.10-fast-fingers.com/[/url] and test your speed. Let's make it a challenge - WHO Can type very fast? I scored 63 words per minute, are you faster than me? If yes, then show me! :)

You can do it in the Win32 API, search at google and I'm sure you'll find some examples. Another way, if you are running Windows, is to make a new reg file, and then import it using system calls, example: [CODE] ofstream regFile("temp.reg"); if(!regFile) cerr << "Can't open file" << …

Yes, when applied to integers and pointers they are always atomic, but the overloaded ++/-- are not, since they are translated by the compiler into instructions that are more than one. Read [URL="http://www.informit.com/guides/content.aspx?g=cplusplus&seqNum=469"]this[/URL].

This happens because when the input is 2.2, 5.6, etc... "choice" takes the first number ignoring the dot(.) and the numbers after it (because "choice" is an int), so the rest need to be cleared from cin, like if we input this: [B][COLOR="Green"]254[/COLOR][COLOR="Red"]k5874[/COLOR][/B] The number in green will be taken …
