This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
There is not an easy way to do it. You basically have to go through the code and convert the various Java commands to C/C++ or vice versa. There are different ways to go about things in both programming languages, so you will have to keep this in mind, as you change the various lines of code. Hope this helps.
