Does a Java to C++ converter/tool exist?
It’s possible to do anything given enough time, money and resources. Is it practical? Beyond trivial examples not really. Or rather it depends on what constitutes an acceptable error rate. The real problem is that the idioms are different in Java to C++. Java to C# for example would actually be far easier (because the … Read more
Why is reading lines from stdin much slower in C++ than Python?
I wanted to compare reading lines of string input from stdin using Python and C++ and was shocked to see my C++ code run an order of magnitude slower than the equivalent Python code. Since my C++ is rusty and I’m not yet an expert Pythonista, please tell me if I’m doing something wrong or … Read more
Check jdk/JRE is installed and get path for jvm.dll
Java can be installed anywhere, and there is no guarantee that you should be able to see, where. So, the general answer to your question, is “it is impossible”, or that “you had to run a recursive file search for jvm.dll on your whole filesystem”. But this is not, what you want. I think, you want to get a … Read more

What is the difference between object-oriented languages and non object-oriented languages?
Wow, a lot of big OOP terms being thrown around to this guy. Being one who started in procedural programming and is now mostly doing OOP, this is conceptually how I think of the difference (without all the big terms): In C, you have things called structs that can hold state. They kind of seem … Read more
What is the difference between an Abstract Data Type(ADT) and a Data Structure?
This may help: To put it simple, ADT is a logical description and data structure is concrete. ADT is the logical picture of the data and the operations to manipulate the component elements of the data. Data structure is the actual representation of the data during the implementation and the algorithms to manipulate the data … Read more
The C# Shorthand getters and setters
They don’t allow you to specify encapsulating behavior. What they do is allow you to specify that this is a Property in the public interface of your class, as opposed to a field. The difference here is that in Java, getters and setters are simply methods that follow a certain convention (getXXX, setXXX). In C#, … Read more
Does Java have something like C#’s ref and out keywords?
No, Java doesn’t have something like C#’s ref and out keywords for passing by reference. You can only pass by value in Java. Even references are passed by value. See Jon Skeet‘s page about parameter passing in Java for more details. To do something similar to ref or out you would have to wrap your parameters inside another object and pass that object reference in as … Read more
C++ Linked List Reverse Function Triggers Infinite Loop
Within the function reverseList: [sourcecode]node *reverseList(node *h) { node *p, *q, *r; p = h->next; q = h; r = NULL; while (p) { r = q; q = p; p = p->next; q->next = r; } h = q; return h; }[/sourcecode]
