Programming tools were initially designed to support or complement programming languages by providing the functionality and features these languages did not have. Typically, they are standalone utilities that provide or support a particular task within any phase of the development/programming cycle. For example, a debugger is a programming tool that helps programmers identify and resolve bugs within a program’s source code. Compilers, linkers, assemblers, disassemblers, load testers, performance analysts, GUI development tools and code editors are also all forms of programming tools.
