 | If you want to see the source code for std templates such as list then just look at the header file. But be prepared for some pretty awful looking code :) The ones from Microsoft are nearly unreadable, at least it is for me. |
 | [QUOTE=Lardmeister;1099623]It just doesn't make much sense to give a chicken elaborate rights and then eat it.[/QUOTE] My thought about animal rights is not to treat them as humans, but to treat and/or kill them humanly -- animal rights does not prohibit slaughtering chickens for food, but rather raising them so …  |

| | >>i wish to develop software on my own. That's a bad place to begin. Start by working with a team of programmers so that you can take advantage of their experience and knowledge. Have you completed a college bachelor's degree yet? If not, then you need to do that.  |
| | operating system? compiler? we need a few more details |
| | Please post the way you declared those variables. Is [b]input[/b] a character array? You generally don't have to do a thing to convert char* to unsigned char*. typecasting is sufficient. And ultoa() takes an unsigned long int as the first parameter, not an unsigned char.  |
 | What you posted is not a double linked list but just an array of People classes. Post the node structure of the linked list you are using. The j loop starting on line 7 should start at (i+1), not 1. There is no reason to compare anything from 0 up …  |
| | If the 8 bit variable is passed by value then there should not be a problem because the compiler doesn't pass 8 bit values anyway, the smallest that can be put on the stack is 16 bit variables (with a 32-bit compiler on an Intel beased computer). Casting can lead … |
| | There were a lot of compiler changes between the two versions that you are using -- 6.0 and 2008. One of the changes is that 2008 uses UNICODE strings by default. You can begin to analyze your problem by turning off UNICODE. Go to menu Project --> Properties (at the … |

| | Re: Best IDE for C? vc++ 2010 Express. Most IDE's and compilers will compile both C and C++, depending on the file extension is *.c or *.cpp or *.cc. It will also depend on the operating system you are using. |
 | I would probably write a batch file that contained the compiler parameters you want and then call that from Notepad++'s Run menu item. |
| | I'm confused. You want a std::list of matrices -- each node in the std::list contains a different matrix? Something on this order? [code] #include <list> class matrix { public: matrix(int rows, int cols) { data = new int*[rows]; for(int i = 0; i < rows; i++) data[i] = new int[cols]; … |
| | >>sPtr=&s; Wrong. should be [icode]sPtr = s;[/icode]. But you really don't need that line, or the previous line, at all since both variables are being initialized on line 1 of the code snippet you posted. This worked for me [code] #include <string> #include <iostream> using namespace std; class someclass{ public: … |

 | If you don't want to do it in Excel or as a CVS file as previously mentioned, then I'd go with VB.NET because I think it has built-in support for Excel files. But then I could be wrong because I don't know a whole lot about vb.NET. |
 | >>how do I run my .cpp notepad files via the command prompt? Depends on the compiler you install. There is lots of information about how to create make files for MinGW, which is the MS-Windows port of *nix g++ compiler. Or you can just compile it without a make file. …  |
| | The result is undefined behavior because of the ++ operator. max() evaluates both variables a and b twice, so the ++ operator gets executed twice. Exactly what the final result will be is compiler implementation dependent. Your compiler may produce one value while another compiler may produce something else. |
 | Its a two-dimensional array of strings. Simething like [icode]string Rule_Collection[100][2];[/icode] except that using vectors is much more efficient because the dimensions are not hard coded. I've often used the same or similar technique for reading rows and columns (result set) from a database. Where the inner-most vector represents the columns … |
| | "new double" is not a variable. "new" is a c++ operator that allocates memory from the heap, and "double" is the type of memory that new will allocate. |
| | One reason its named "Visual C++" because its a c++ compiler/IDE designed to make writing MS-Windows programs easier. Otherwise it will compile standard c++ programs without a problem unless you try to use something from the newest version of c++ standards which vc++ has not yet implemented. But then most … |
| | >>do i have to use the get function to get the numbers from the user? No -- get functions return the value of private members to the calling function or class. For example [b]get_invoiceAmount()[/b] should be an int function that returns the invoice amount (re-read your instructions on this). With … |
 | esi just contains an address that is within the ds segment. ds is not a pointer -- it contains the address of the data segment. Sometimes you might even see cs:[esi] or even ss:[esi] in which case esi is pointer to somewhere in the code segment or stack segment, respectively. |
| | There is no one language to do all that. Writing desktop applications will require different languages and compiler than writing web based applications. And writing mobile applications is still different from either of the other two. First determine what it is that you want to write and then select a … |
| | Re: Exit() The paramarater is the value that the program will return to the operating system so that other programs can use it for some purpose. The value 0 traditionally means the program exits normally without error. Any other value would mean the program encountered some kind of error. The value of … |

If you are going to post code snippets that everyone might want to use then don't use non-standard functions like that one. >>cout<<count; >>cout<<" "<<"+"<<" "; You can abbreviate that into a single statement: …  |
 | Why?? I'm sure it was a lot of fun writing that program, but there are already been several similar programs for a long long time, for example Notepad++. And I'm not about to download and run that *.exe program. That's one way viruses are spread. |
| | You should be able to learn C and C++ from *nix without any problems -- the language itself is platform independent. You run into cross-platform problems when you start writing programs that call platform-specific functions, such as GUI and hardware. But for learning the language *nix is a good as … |
| | getch() returns two bytes, not just one, when you press special keys such as arrows and function keys. I like to make the keys negative values so that the program can easily distinguish between special keys and normal keys, but there are other ways such as add 255 to the … |
| | Create a small program to test out that function and find out how it works. I don't use that compiler so I can't help you very much. Working with small two or three line programs is a lot easier than trying to work with large programs and DLLs. |
| | Are you talking about *nix or MS-Windows? |
| | Re: memset() VS for If you want to initialize the array to 0 then just declare it like this: [icode]int prime[200000] = {0};[/icode] and the compiler will most likely use the optimal way to initialize it. |
| | post the code how its reading the data. |
| | >>or show me a 32 bit BGI compiler There isn't one. AFAIK Borland itself doesn't even support BGI in its current compilers. You will have to upgrade your skills and use something like Code::Blocks or VC++ 2010 Express, both are free. |

| | >>- i want to know if this is possible Why not? You could also declare them as [icode]int a, b, ab;[/icode]. If you put that in a header file then you have to use the [b]extern[/b] keyword in the header file, e.g. [icode]extern int a, b, ab;[/icode] then do the … |
| | Using a 64-bit compiler instead of a 32-bit compiler may also make malloc() allocate more memory. Just because you have a 64-bit computer doesn't mean the compiler is going to produce 64-bit code. If you are using gcc or g++ then I presume it has flags to enable 64-bit compiles. |
