Convert Java to C++?

leanieleanz · 03-03-2005, 08:11 PM

Is it possible to convert java programming code to c++ code? I have a C++ program I need to turn in but did it in java first because that is what I know. I then go through and convert it manually...it makes it easier for me. Is there a way I can just convert the code with a tool?????? I use .NET

Any input is greatly appreciated as the program is due in a couple days

Microsoft makes a Java to C# conversion tool. Also ANTLER (a parser-parser) has some languages that may do the trick. However, it looks like you are under the gun with a deadline. I suggest that you make a pot of coffee and get to work. Fortunetly Java to C++ is fairly straightforward, not like Java to ... COBOL?

Hope this helps..

Okay thanks BubaDragon....but what is the Microsoft conversion tool called and how do I get it? That would help! Unless you just want to do it for me (joke)

Thanks!!

I don't think converting your Java to C# would be of much help... as C# and C++ are just about as different as Java and C++.

It seams to me, if you know Java well you should have the design philosophies down pretty well. If that is the case, then largely all your dealing with is syntax differences (ok... some other differences as well, but nothing that should be past your understand)... You'd probably be doing yourself a bigger favor if you got ride of your dependence on Java and just did everything from scratch in C++. It might be a little painful at first... but it is probably better for your learning.

The mark of a good programmer isn't his/her ability to code in a particular language.. it is his/her understand of programming and datatypes in general, and his/her ability to quickly pick up a new language in a new environment.

I am okay with C++ but not when it comes to array's. I am having a very hard time programming with arrays in C++! It is my only C++ class and I am not worried about knowing how to be a C++ programmer....since my bachelors is on Open Systems Technology (Linux administration) So it is very stressful trying to figure it out, thats why I would love to use a converter. The tutor that usually helps me out is on vacation

My code is as follows:

PHP Code:



#include <iostream> 
using std::cout; 
using std::cin;

Anyone want to make a few bucks converting it let me know.

Your C++ program is lacking comments ...
