 | >I think you're right on that one. It depends on what you mean by "char". If you're talking about the char data type, it's always equivalent to one byte in C++, for whatever the definition of a byte is. I think Vernon is assuming that a byte always equates to … |

| | Re: program crashes >Would anyone be willing to see if you can tell me where my issue is. That's simple enough. Your issue is here: [code=cplusplus] int i, j; [/code] And it manifests here: [code=cplusplus] grid[i][j].row = i; grid[i][j].col = j; grid[i][j].frequency = 0; [/code] i and j aren't initialized. Unless you get … |

 | I don't remember if you agreed to do it, but a full back history of reputation comments (as opposed to the most recent 15) in the user control panel would be fab. |
| | If it's an exact match, you can use the Contains method from the string class. If it's more of a fuzzy match, you can use regular expressions with the Regex class. |
| | >does anyone know if there is a code in c++ that allows print on paper instead of monitor? Communicating with specific hardware is outside the bounds of standard C++. If you want a good answer, you need to tell us what compiler you're using and your operating system.  |
| | Re: Simple question OffsetX is a read-only property, so all you can do is get the value: [code=cplusplus] x = my_matrix->OffsetX; [/code] |
| | >Please, where I'm wrong? You're mixing up pointers to functions and pointers to member functions. A pointer to a member function (which is what you want) must be called on an existing object: [code=cplusplus] MTP::Application obj; (obj.*mExtVoid) ( true ); [/code]  |

| | Re: about #pragma >I wanted to know where will the selected message will be printed? It's a part of the preprocessor, therefore it's a compile-time operation. Logically, you can expect the message to be printed in the compiler's output. In Visual Studio that's the output window (Ctrl+Alt+O). >Can you give me a working … |
| | Re: objects >Temperatures degrees(); You stumbled on an annoying and subtle problem with C++'s declarations. What this does is declares a function called degrees that takes no parameters and returns an object of type Temperatures. Remove the parentheses: [code=cplusplus] Temperatures degrees; [/code] |

| | >I'd be eternally grateful if someone could explain this in detail or point me to a good link? [url=http://docs.sun.com/source/806-3568/ncg_goldberg.html]Here's a good link[/url], but the short answer is that due to floating-point imprecision, simply changing the order of arithmetic operations can affect the accuracy of the result. |
| | Re: Classes 1) You have more control over who accesses your data and how they access it. For example, let's say you have a telephone number in the class represented by a string. If the variable is public, anyone can set it to anything. This means that your class can't assume the … |
| | Every function parameter is passed by value in C. Pass by value means that a copy of the value is made and you access the copy from within the function. For example: [code=c] #include <stdio.h> void foo ( int bar ) { printf ( "%p\n", (void*)&bar ); } int main … |
| | 1) This looks like a perfect place to run a simple test on your own: [code=cplusplus] #include <iostream> class Base { public: ~Base() { std::cout<<"Base\n"; } }; class Derived: public Base { public: ~Derived() { std::cout<<"Derived\n"; } }; int main() { Derived d; } [/code] 2) Sure, if you want … |
 | >Why is it that I cannot call th method in RTC::displayParameters() with >the template-argument mStruct* when it is clearly a constant reference? Because it clearly isn't. Let's start with the fact that <mStruct*> is a syntax error. The closest interpretation would be to call the instantiation of displayParameters using a … |
| | >How is that occurring, by adding an extra dimension to array it takes both words. It helps to know that the native string type in C++ is actually an array of char, and cin's >> operator is pretty smart about knowing what types you give it. When array[i] is an … |
| | >you didn't hint on an answer to my original question. It involves creating your own graphics and piecing them together manually. I'm not familiar with Qt, but it might give you the option of skinning your interface, which simplifies the piecing together part. |
| | >but can u just make the >int x and int y public instead? You can, but public data is typically a bad idea because it means you're giving full control over the values to everyone. Most of the time you don't want to do that, which is why public or … |
| | If you just want to use hash tables then the TR1 libraries are sufficient (assuming you have them). If you want to learn how hash tables work, then a good start would be [url=http://eternallyconfuzzled.com/tuts/datastructures/jsw_tut_hashtable.aspx]this tutorial[/url]. |

| | Instead of putting all of that framework around your loop, first get a simple loop working so that you know what's needed: [code] #include <iomanip> #include <iostream> using namespace std; void table_row ( int multiplier ) { for ( int i = 1; i <= 12; i++ ) cout<< setw … |
 | I don't see the benefit of goto here. If your code is properly modularized, displaying the mission menu amounts to a single function call, so jumping around with goto doesn't really buy you anything. I'd conclude that you should refactor before considering a solution with goto. |
 | IIRC, Dani doesn't allow popups, or flyins, or anything obtrusive in her agreements with advertisers. I'd suggest sending her a screenshot when you get it again, because the advertiser may be in breach of contract. |

| | >I slacked off in class while my teacher was teaching us At least you're honest. That won't stop most of us from letting you sit in the hole you dug for yourself, but it's a breath of fresh air nonetheless. |
| | >Well partner, it's a start! If by start you mean poor quality code that doesn't address the problem at all, yes. |
 | Put another loop inside that loop. You want to print (digit+1) asterisks and then a newline.  |
 | "Much better" is debatable, but you can make use of the constructor that takes an iterator range: [code=cplusplus] vector<double> V1(Model.begin() + StartModel, Model.begin() + EndModel); [/code] |
