 | There's a point at which an introduction is unnecessary. You would already be too famous (or infamous). |
| | I kind of missed the part where you described what the output was supposed to look like. Can you post it again for me? |
 | DB was lame. DBZ had one or two good scenes. DBGT also had some good scenes, but it went too far over the top to be as good as DBZ. |
| | Re: Randomness >dont make your explanation too complex, as i am only 19. 19 easily makes you an adult, so that's not an excuse to pretend you're stupid. Perhaps "I'm not too familiar with the topics, so don't make your explanation too complex". >if you could tell me what the course entails,and …  |
| | >any mathematical equation involving numbers 10 and up would be (as >far as I can see) impossible to directly deal with. You can perform any kind of input using single character input. In fact, that's basically what all of the other input functions do: they read one character at a …  |
 | Your problem is that opening and closing files doesn't change the stream state. When you read fin to end-of-file, closing the stream doesn't change the eofbit. You need to clear the stream state as well as close the file if you plan on using fin to read from a file …  |
| | >Is this possible? Yes. When you pass cin an integer type, it tries to read and format an integer. If the string it reads isn't a valid integer, it'll fail. You can use that to validate the input and try again: [code] #include <iostream> #include <ios> // For streamsize #include …  |
| | >You can use atoi to convert the char to a int Or not, seeing as how atoi is a demon spawn. Use strtol instead, or since this is C++, stringstream or Boost::lexical_cast. Examples are common and can be found with this forum's search feature. |
| | Re: read from folder C++ doesn't know what a folder is. That kind of operation is dependent on the operating system, and the solution will use a system specific function or class of functions. So, what compiler and OS are you using? |
 | Have you written a function that tells you the height of a binary search tree? If you have, you can use the same principles to solve this problem. If you haven't, you need to do a complete traversal of the tree (recursive is easiest) and for each node, return the …  |

| | value is an array. When you pass it as the second argument to get, it acts as the initializer for the std::string parameter. You've lost your reference, and any changes to the parameter will not be reflected back in displayAll. Change value to a string and pass it by reference … |
| | >public void itemStateChanged(ItemEvent ie) Either that's a typo and ie should be e, or you need to change any use of e to ie.  |
| | In againstComputer, the first if statement needs braces. In main, when you test move, you used else instead of else if twice. And you use cMove before giving it a value in againstComputer. |

| | Every different program that uses a static library has its own copy of the library built in. A shared library only has one copy and every program that uses it just references that copy. How you create them depends on the tool you're using, and how they're named depends on …  |
| | First and foremost, C++ is a language and Visual C++ is a tool for writing in C++. The difference Visual C++'s are different versions of the tool. VC++ 6 is the oldest version you mentioned, then VC++.NET, then VC++ 2005 Express. Don't use VC++ 6. It has bad C++ conformance, …  |
| | >char *p = "india"; This is a pointer to a string literal. When you return p, you're returning the address of the string literal. A string literal has a lifetime beyond the function, so the memory isn't reclaimed and you don't get garbage. This is perfectly legal. >char p[] = … |
| | Re: hex converting >shall i convert this address into hex before searching? Not unless you stored it as hex. >as i'm searching in a file in binary mode? This has nothing to do with hexadecimal. |
| | Re: binary file >which datataype can my input take. The same data type you used to write it if you want a meaningful comparison. If you're just checking for equality, you can use unsigned char and compare every byte individually. >also, the comapred stream is in this form 0004a4900 >i made this stream … |
| | Re: problem with C++ Change this: [code] double M2_0(c,m) double c[160]; double m[16][5]; { [/code] To this: [code] double M2_0(double c[160], double m[16][5]) { [/code] C++ doesn't support the old C-style function declaration. C also no longer supports it, so I don't recommend using it in C either. |
| | Put simply, inheritance is saying that one class is a part of another class.: [code] class A { public: void foo() { cout<<"foo\n"; } }; class B: public A {}; [/code] You can create an object of B and call foo because A is a part of B. B is …  |
| | Based on my limited knowledge of such matters, why don't you try putting the cin.get just before main returns? |
| | >oes anyone know which include file is needed for functions; IsLetter (ch) and ToLower(ch) ? There are no such functions in standard C++. The cctype header has isalpha and tolower, which is probably what you're referring to. |
| | Re: from C++ to C# The hardest part of learning any language is forcing yourself to write logically in that language. It's pretty easy to write C++ in C# because there are many similarities, but that's not necessarily good C#. |
| | Most of my posts are in the software development category or the private forums.  |
| | Sorry, I have no idea what you're asking. Try rephrasing your question. |
| | >The code processes millions of transactions, but less than .01 % has this error. Any ideas? That's a typical floating-point rounding fudge. If it's a serious enough problem, you can try to use a more precise type such as long double, or remove floating-point altogether to maintain exact precision. Though … |
| | >how do you know which one is going to be applied in what you do or how good the code will stay up? Experience. >should I expand into other codes Eventually, but learning too many languages at one time will just confuse you. |
| | Re: c++ music The C++ beep is all you get. If you want different notes, you need to go lower (and try to access the hardware, which isn't portable and probably won't work) or go higher (and use a library that lets you produce notes from the sound card rather than the internal … |

| | >In an ordinary four-function calculator, are the ( and ) keys available? No, it's strictly a single operation at a time process with the result of the last operation as one of the operands.  |
| | I disabled scripting and the site is actually usable now. ;)  |
| | Eventually you'll realize you ask pointless questions with no answer and start coming up with better ones.  |
 | Re: putback() ? Yes, you can use putback: [code] #include <iostream> int main() { char ch; int i; std::cin.get ( ch ); std::cout<<"You read "<< ch <<'\n'; std::cin.putback( ch ); std::cin>> i; std::cout<<"You read "<< i <<'\n'; } [/code]But if you start to use anything more complicated than just this, it would be … |
| | Can you post the definition of queueType? It's hard to test when the code won't compile. |
 | >but how can this be done using 32-bit, since 32-bit is protected by the OS. Access that functionality through the Win32 API, just like everyone else. It's trivial with MASM (as trivial as anything in assembly can be) because the assembler is written with Win32 applications in mind. Check your … |
 | Re: union The short story is that a union is like a structure except each member shares the memory. The result is that a union takes up less space, but you're also restricted to using a single member at a time. |
| | Include <stack> and <queue>. You can also use a vector or deque as both a stack and a queue at the same time. I'm sure that's not what you meant, but we don't just give away code that smells even a bit like homework. |
| | >entry->set(NAME, AGE, JOB); This is equivalent to: [code] (*entry).set(NAME, AGE, JOB); [/code] The arrow operator dereferences your pointer for you and then grabs the member you specify. |
| | Let's play a game. Why do you think maintenance [B]doesn't[/B] cost more than development? |
| | You're getting into the realm of needing a makefile. Ask man about the make utility. |
| | The downloaded version of GCC isn't a trial version or an educational version. It's the real thing. And it handles large programs about as well as any other high quality compiler. |
 | Could you please stop resurrecting year old threads? |
| | Write a shell script that creates the file for you, then opens it using gedit. |
| | >for >char name[20]; >use >cin.get(name,19); He's already using std::string. Why are you suggesting that he downgrade to C-style strings? Oh, and you have an off-by-one logic bug. The size argument to get should be 20. Finally, you should recommend getline instead of get, because get has the potentially confusing feature … |

| | >main() int main ( void ), and you need to return an integer. >printf("size=5d\n",res); Format modifiers always start with a %, so you need to say %5d, not 5d. >int sizeOf( void var) You can't have variables of type void. >return((char*)&ptr[1] - (char*)&ptr[0]); This is undefined behavior. You're accessing a … |
