Expert Solution & Answer
Chapter 1, Problem 25RQ
Explanation of Solution
Three general methods of implementing a
The Three methods are:
- Compiler Implementation.
- Just In Time (JIT) or Interpreted Implementation.
- The combination of both compiled and interpreted implementation.
Compiled languages are usually faster during execution.
- Firstly, the program is passed to lexical analyzer which gathers different lexemes like keywords, punctuations and others of the code.
- This information is then passed to syntactic analyzer which makes parse tees out of this information.
- Further, the code is then converted to an intermediate language and the semantic errors and rectified in this stage.
- Finally, the code in this intermediate language is then converted to machine code which can be run by the system...
