Through experimentation, I found that this is also legal-- [code=c++] #include <iostream> class Base { public: virtual void fn(){std::cout<<"fn base\n" << std::endl;} virtual void myfn(){std::cout<<"myfn base\n" << std::endl;} }; class Derived : private Base { private: void fn(){std::cout<<"der\n" << std::endl;} void myfn(){std::cout<<"myfn Derived\n" << std::endl;} }; int main(){ Derived d; …

Why not encapsulate what produces the sound in a thread and execute multiple versions of the thread (where upon initialization, you specify a String for the file to read to get the .wav file to play)? Edit: Oh I just noticed you're producing sound based on numbers and not a …

A few questions... First, why do you declare two arrays and define them full of spaces then iterate them through loops to assign space characters to them when they already have that value? You can reduce code-bloat by simply instantiating your arrays to have 12x12 characters. Furthermore the initial value …

I think you need to be more concise with the requirements. You have 30 strings correct? Does this mean that they each cannot be more than 20 characters long (including the null terminator)? You must make your char[20][30] (or most likely char[30][20]) in pointer form, then convert it into an …

Why not store the current time in a data type (like a long) when the key is pressed and when the key is released subtract the new time from the old time?

Most companies that I know that use Cobol are moving towards Java. I'd guess that being, strictly a Java developer would be much more ideal in America, though I do not know about anywhere else. Then again if you want to companies migrating from Cobol to Java you would probably …

Is there any real different between using an union between two types and a reinterpret_cast between two types, for example-- [code=c++] #include <iostream> int main(){ union{ unsigned short *a; float *b; }; float value = 0.6f; b = &value; std::cout << *a << std::endl; unsigned short *s; float *f; f …

Oh boy, there is a lot of wind being blown in this topic. To simplify things, everything sent to a function gets copied (or generates an object) if-- -An implicit cast is done (sending an int to a function that takes an Integer object for example (and for further clarity, …

My first question to you is... Do you know what the different between an interface and an abstract class is? O_o

Ok one big thing to note, before anything else-- [code=c++] vector<vector<double>> [/code] -- is not a portable statement because >> may (depending on the compiler) be analyzed as the right bitshifting operator and throw an error. You'll want to space out those symbols. [code=c++] vector<vector<double> > [/code] Edit: Also I …

Although I haven't attempted it before, I'd assume you'd have a particular zone renderred on the screen with a type of "cover" over it. Either that or only render certain pixels ahead of the borders on a pane. The position of your character would, obviously determine when the screen will …

Although I'm Atheist, I swear to god I got dumber from reading this topic.

I'm pretty sure it's something along the lines of-- [code=java] Runtime.getRuntime().gc(); [/code] Or the long way-- [code=java] Runtime rt = Runtime.getRuntime(); rt.gc(); [/code] I do believe you can do the same using System instead of Runtime (without calling getRuntime - just System.gc() ) This simply suggests for the Garbage-Collecting threads …

Don't forget what classes are for! Classes are things capable of having behavior and encapsulating information. Encapsulated information can be data, but it's slightly beyond just that. Behavior can be considered a method, but it's slightly beyond that as well. If you're not worried about the stats of a unit …

I strongly suggest that you re-read and brush up on C++ syntax before attempting this project. You may end up getting it to work as you are now, but it will either take an incredibly long time, have a lot of errors and/or cause you nothing but headaches. Even if …

Hello I'm reading through Scott Meyer's book Effective C++, third Edition. I'm having an issue understanding Page 14, Item 2, paragraph 4.

I'm enjoying the book Effective C++. It has highlighted things that I've looked over, never heard of, or never even though of before! However, even with this book my understanding of C++ still doesn't seem to be solid. For some time now I've been curious about how binary data is …

To make this easier, you might want to consider using a Server class that encapsulates a ServerSocket and has an array of Sockets. The ServerSocket will be used to establish the Server, while the array of Sockets will be used for awaiting Clients (via ServerSocket.accept() ). Attached is a poorly …

I made a correction but the code is slightly different. There were some errors in your code, such as assigning a String to the String[] reference and not an actual indice of the String array.

I've read up to the point where the author explains partial classes. I understand the general concept - they're used when a class is so big that it is better to split it across files. I created two .cs files. Let's say one is CS1.cs and the other is CS2.cs …

Ok, you're confusing the phrase "do what I mean" with Java syntax. I strongly recommend for you to read the first link presented here on this forum and get some pointers on how to code syntactically correct Java-style. Also it would help if you posted your code in Code-tags-- [url]http://www.daniweb.com/forums/misc.php?do=explaincode&TB_iframe=true&height=400&width=680[/url]

Use code tags please, otherwise if people try to copy/paste your code they will most likely get # symbols that they'll have to manually delete. Not to mention that there's no telling if the code will be indented properly (which means more work for people testing your code).

Yes, including a throws on the end of main is considered bad programming practice since nothing can really catch an error generated from main and handle it afterward.

Do you simply want a separate pointer for the data?

To invoke function of a class through pointers, you may have to use a pointer to a member function. Your vector will have to store MtFP's instead of regular FP's.
