Question

1. State the differences and commonalities between compilers, interpreters and pseudo interpreters in tabular fashion.

Answer 1

Compiler	Interpreter	Pseudo interpreter
The language processor that is used to convert source code (high level language) to object code (machine language) as a whole in one go.	The language processor that is used to convert source code to object code line by line.	The language processor that is used to convert assemble level code to object code.
It takes large amount of time to analyse the entire source code	It takes little amount of time to analyse the source code	It takes the time somewhere between a compiler and an interpreter to analyse the source code
The overall execution time is fast	The overall execution time is slow	The overall execution time is somewhere between a compiler and an interpreter
It creates a intermediate code	There is no intermediate code created	There is no intermediate code created
It generates the error message only after scanning the whole program	It generates error as and when found	It generates error as and when found
debugging is comparatively hard as the error can be present anywhere in the program.	Debugging is easier as we know where exactly the error is present	Debugging is easier as we know where exactly the error is present
Memory requirement is more	Memory requirement is less	Memory requirement is less
Program need not be compiled every time	Program needs to be converted from high level to machine level language every time	Program needs to be converted from assembly level to machine level language every time
Example: gcc, Microsoft Visual Studio etc	Example: python, LISP, Ocamle etc	Example: GNU Assembler, MASM etc
