·       procedures involving heavy−duty math operations, especially floating point arithmetic, arbitrary

·       cross−platform portability required ( C  should be used instead)

·       complex applications, where structured programming is a necessity (need typechecking of variables,

·       function prototypes, etc.)

·        mission−critical applications upon which you are betting the ranch, or the future of the company

·       situations where security is important, where you need to protect against hacking

·        project consists of subcomponents with interlocking dependencies

·       extensive file operations required (Bash is limited to serial file access, and that only in a particularly

·       clumsy and inefficient line−by−line fashion).

·       need multi−dimensional arrays

·       need data structures, such as linked lists or trees

·       need to generate or manipulate graphics or GUIs

·       need direct access to system hardware

·       need port or socket I/O

·       need to use libraries or interface with legacy code
