Explanation:

Old (legacy) systems that have been corrected, adapted and enhanced extensively require
reengineering to remain maintainable. Reengineering is a rebuilding activity to incorporate new
technologies into existing systems. Using program language statements, reverse engineering
involves reversing a program’s machine code into the source code in which it was written to
identify malicious content in a program, such as a virus, or to adapt a program written for use with
one processor for use with a differently designed processor. Prototyping is the development of a
system through controlled trial and error. Software reuse is the process of planning, analyzing and
using previously developed software components. The reusable components are integrated into
the current software product systematically.
