• BruceVik Retrieving specific digits of a variable value

  Hi guys, I just had a quick question. Say I have the user enter a value for a variable, x. How would i pull a specific digit from it So if the value put in by the user is 23, it will assign 3 to the variable. Or if he enters 234619 it will take the 9 and assign it to x.

• Ramon Casha Mixing Templates and Generics

  I think I've raised this questions a couple of times and the first time some three years ago - and have never got a real answer. Why does the language disallow mixing templates and generics. What's wrong with: template < typename T > value struct outer {   generic < typename U > void foo(); };   or generic < typename T > ref struct outer {   template < typename U > void foo(); };   ...Show All

• Kapadia Shalin Shouldn't this generate a warning? (const, non-const)

  class foo{    void bar( const long var_name); };   void foo::bar(long var_name){ }   Since it's declared const in the class, shouldn't the member definition need to be const as well I understand that from a code generation point of view it may be irrelevant, but it strikes me that seeing this would mean that the coder made a mistake since and would have intended for them to agree. ...Show All

• Stefaan Clement 'Long' using 12 bytes rather than 4?

  I am new to Visual Studio/ C++, so have been working through a book. As with other text books, it suggests checking that long variables take 4 bytes and that consecutive variables are separated by 4 bytes. Using 'sizeof' on two variables gives 4 bytes each, but looking at their addresses shows a separation of 12 bytes. (I am using Visual Studio 2005 version 8.0.50727.42.) Using my Borland compiler, on the same code, gives 4 bytes seperation. ...Show All

• Kelvin Tse Intrinsic available for reading CPU flags

  Hi. I'm looking for intrinsics that allow me to read CPU flags, especially the carry flag would be important to me. I'm writng x64 application so I have no possibility to use the inline assembler therefor. I would need the flag register to check wheter a value assigned to an unsigned __int64 caused an overflow. Thanks in advance, Trenor seems without inline assembler, it's hard to retrieve the flag register. ...Show All

• Leedo Exporting functions with _declspec(dllexport)

  Hi, I have a DLL library and I export classes from this library. All classes and their method are properly exported and can be seen in "dumpbin /symbols mydll.dll" output. I use the standard _declspec(dllexport) and _declspec(dllimport) approach.

• atreat circular reference in parent/child classes

  I have been trying to understand some code that another guy wrote, and though his code compiles and runs, it seems like it should never have compiled. He has 2 classes. One class is basically the parent, and it includes a pointer to the child it creates. As the child is being created, the parent passes the constructor a "this" pointer, so the child can later access variables in the parent. When I try to duplicate this logic, ...Show All
