 | Hi all, I've browsed the net trying to find a paradigm to describe what I'm looking for but haven't been successful. So I'll try to explain it as succinctly as I can. Right now, for my PhD research, I've set out a few applications that take input files that have … |
| | Hi all, I've been struggling with something for a number of weeks now and I just can't seem to solve it. I've got a bit of code that looks as follows: [CODE] class classA { public: classA( ); ~classA( ); classBBase* pointerToClassBBase; protected: private: }; class classBBase { public: classBBase( … |
| | Hi all, I'm busy writing a generic textfile reader class and I'm struggling to write the code to deal correctly with end-of-line (EOL) characters for Mac, Linux and Windows. I've done a fair bit of reading on the issue and I came up with the following function within my TextFileReader … |
| | Hi all, I've setup a class within my software package to read generic text files. For this, I'm using the getline( ) function and then parsing each line for specific types of files. In setting this up, I've come across the ACSII incompatibilities between Windows systems and Unix systems. I …  |
| | Hi all, I've got quite a simple question and after searching here and on other websites I can't seem to resolve what the "correct way" of doing this is in C++. Below is a simple piece of code illustrating what I am trying to do: [CODE] #include <iostream> class BaseClass … |
| | Hi all, I've scoured the internet for examples that would allow me to figure out how to apply functors in my specific case, but I just can't seem to make the shift from the examples I find to figuring out how to use it for my own code. Here is … |
| | Hi all, I've found a few references that address this issue, however I haven't figured out what the solution is in the specific case that I'm dealing with. Hopefully someone can help me out. The following code prototypes the general idea that I'm working with: [CODE] class FooClass { public: …  |
| | Hi all, I am currently working on a large software project for scientific computing for my PhD research. I am working on the architecture for part of the project now, and I am struggling with how to working with a polymorphic pointer as a function input parameter, by reference. The … |
| | Hi all, My title might not describe this problem as well as it could, but I'm not sure what area this problem falls under. I have a simple base class and derived class as follows: [CODE] class BaseClass { public: BaseClass() { parameterA_ = -0.0; parameterB_ = -0.0; } virtual … |
| | Hi all, I have an issue with a piece of code that I am writing. The problem I'm facing is that I have a base class and a derived class, and the base class contains a pure virtual function. I then want to overload the pure virtual function with a … |
| | Hi all, I am in the process of optimizing my code and I was wondering what the fastest way is to compute trig functions. I profiled my code and to my astonishment discovered that one of the most time-consuming processes is computing cos(theta) and sin(theta) using the implementation of cos() … |
| | Hi all, This might be bit of a silly question, but it's stumped me now for over a day and I've scourged the net for info but haven't found anything to sort out what I should be doing. I am currently using Qt Creator 1.3.1 (Based on Qt 4.6.2 (32 … |
| | Hi all, I am trying to write a general function that when called is able to write the value of all the member variables of an object passed to it. This function is part of a class. The class objects that I want to write out each have a member … |
| | Hi all, I was wondering if there is any standard way in C++ (perhaps in the standard library) of handling mathematical equations that are composed of +/- signs. For instance, if you are given the equations: [quote] y = +/- sqrt(x) z = +/- y [/quote] Is there an efficient … |
| | Hi all, I've spent the last week trying to sort this out, and the more I delve into it, the more confused I'm getting. I've done some background research (searched on google and here for sort function issues) and really I can't make head or tail of what's going on. …  |
| | Hi all, I have a simple mathematical series that I need to expand fully and I am not sure what the most efficient way is of achieving this. I know I can write a for-loop quite simply to do this but I don't know if a solution already exists in … |
| | Hi all, I'm busy coding up some classes now and I was wondering if there is any danger in using a variable name twice, if the variable is limited to local scope. For instance, let's say I have the following piece of code: [CODE] class Foo { void function1( double …  |
| | Hi all, I am just getting into the world of OOP and I'm not totally sure in what situations it's better to use objects and when it's simpler to just revert to arrays. For example, I am currently re-writing a bit of scientific code written in C that simulates the … |
The End.
