Abstract:
How to deal with C pointers is an important and difficult issue in C to Java automatic program transformation System. The existing methods are powerless for ingenious C codes. It is difficult to understand codes generated by some transformation system. These codes are not always correct. This paper presents a set of methods. They implements all the functions of C pointer by Java. This transformation keeps original program structure, and runs as fast as possible. Using it can automatically convert various C pointer applications into correct, clear, changeable and efficient Java code.

摘要： C指针的处理是C to Java代码自动转换系统中一个重要而困难的问题。已有的方法大多不能处理含有技巧的指针代码，转换生成的代码难以理解，往往无法正确执行。基于此，提出一种可用Java实现C指针所有功能的方案，该方案在类型转换后不改变原程序结构，并保持尽可能高的运行效率。示例分析表明，运用该方法可使各种类型的C指针运用都能自动转换为执行正确、结构清晰、修改方便、运行快捷的Java代码。
