Software Construction Tools Program editors � Used for the creation and modification of programs, and possibly the documents associated with them � Can be general purpose text or document editors, or they can be specialized for a target language 13 17-May-05 Software Engineering / Fernando Brito e Abreu Software Construction Tools Compilers and code generators � Traditionally, compilers have been non- interactive translators of source code, but there has been a trend to integrate compilers and program editors to provide integrated programming environments � This topic also covers preprocessors, linker/loaders, and code generators Software Engineering / Fernando Brito e Abreu 14 17-May-05 7

Software Construction Tools Interpreters � These tools provide software execution through emulation � They can support software construction activities by providing a more controllable and observable environment for program execution 15 17-May-05 Software Engineering / Fernando Brito e Abreu Software Construction Tools Debuggers � These are considered a separate category since they support the software construction process, but they are different from program editors and compilers Software Engineering / Fernando Brito e Abreu 16 17-May-05 8
