I'm trying something like this and I'm getting errors: [code=c++] class Non_Template { //...other stuff public: template<class T> class some_Template; //declaration }; template<class T> //something WRONG with this syntax Non_Template::some_Template { }; [/code] Err msg I'm getting: error … |

| | Hi, I'm trying to implement my own allocator using malloc and free. One thing what interests me is that in declaration of deallocate in addition to pointer we have also parameter size which suppose to be size of elements allocated with allocate but having implemented my deallocate as this: [code=c++] … |
| | Hi, I've got construction of namespaces like this: namespace one { namespace two { class SomeClass{...}; } } and when I try to use this class (without fully qualified name) in another file (also with nested namespaces) I'm getting errors. It doesn't even help if I place declaration of using … |

| | Hi, guys. Just installed new borland c++ 2010 - I think it's quite cool. One question though, where can I find comment and uncomment command? Thank you |
| | Hi, Just wonder if there is any way to get this information while compiling your source code, what I mean is if I can do something like this: [code=c++] //pseudo code if (IDE == BORLAND) cerr << "You are using: " << _COMPILER << endl; if (IDE == VISUAL_STUDIO) cerr … |

| | Hi, I tried to be clever and wrote template (body below), and something is not working as I would like it to. I have to explicitly cast template parameter on desired type instead of function recognize type (by id() method provided in class object); I don't understand why is it. … |
| | Hi, I know that this topic was discussed previously but those previous threads didn't answer to my question which is: How to change color of this text: [code=c++] cout << "Some text" << endl; [/code] when I'm outside of main, i.e. in file with my class and in one of … |
| | Hi, I would like to ask a question and I'm quite certain that I'll get positive answer to that. When I've change some code in one file and press f5 (visual studio) it seems to me that all other files are being compiled as well as this one in which … |

| | Hi, I've just came across declaration of this form: [code=c++] void fun() throw(); [/code] Could anyone explain what is the pourpose of this and maybe someone knows good book with thorough explanaition on this subject. Thank you |
| | Hi, I've got problem with method ignore from cin. This is my code: [code=cplusplus] void _name() { string name; char ch = 0; bool name_accepted = false; cout << "Enter your name: " << endl; while (!name_accepted) { while (ch = cin.get()) { //cin. if (isalnum(ch) || isspace(ch) || ispunct(ch)) … |

| | Hi, Just wonder is there any way to display enum as enum not as integer? Thank you.  |
| | Hi, in my code below if I move scope protected below public just as I would like to see it this code won't compile. I always thought that order of members in class is without any importance but here I see something different or I'm doing something wrong? Thank you. …  |

| | Hi, I've tried to output pointer in decimal but can't do it [code] int a = 10; int* p = &a; cout.unsetf(ios_base::hex); cout.unsetf(ios_base::oct); cout.unsetf(ios_base::dec); cout << showbase << dec << p << endl; [/code] it still shows this output in hexadecimal format. Any reason why this doesn't work. Thanks in … |

| | Hi, it's me again, Another two problems which I'm having with this example is that when in ofstream constructor I specify mode as binary: ofstream fout("my_file.txt", ios_base::binary); nothing is written to a file (at least I can't see there anything) and another problem which I cannot cross is that I … |
| | Hi, I'm trying to print to a file some data of objects and I'm trying to do this in pseudo xml format so my file would look like let's say: <node> data </node> I'm using write method: [code = C++] fstream fout("my_file.txt"); fout.write("<name>", sizeof(7)); fout.write("\n", sizeof(2)); fout.write(this->name(), sizeof(this->name()).length()); fout.write("\n", sizeof(2)); … |
