COMPILER DESIGN - TOP-DOWN PARSER http://www.tutorialspoint.com/compiler_design/compiler_design_top_down_parser.htm Copyright © tutorialspoint.com We have learnt in the last chapter that the top-down parsing technique parses the input, and starts constructing a parse tree from the root node ...
COMPILER DESIGN - RUN-TIME ENVIRONMENT http://www.tutorialspoint.com/compiler_design/compiler_design_runtime_environment.htm Copyright © tutorialspoint.com A program as a source code is merely a collection of text code, statementsetc. and to make it alive, it requires actions to be performed ...
Length of the string is the total number of occurrence of alphabets, e.g., the length of the string tutorialspoint is 14 and is denoted by |tutorialspoint| = 14. A string having no alphabets, i.e. a string of zero length is known as an empty string and is denoted by ε (epsilon)...
Compiler Design - Semantic AnalysisPrevious Next We have learnt how a parser constructs parse trees in the syntax analysis phase. The plain parse-tree constructed in that phase is generally of no use for a compiler, as it does not carry any information of how to evaluate the tree. The ...

Compiler Design - Finite Automata - Finite automata is a state machine that takes a string of symbols as input and changes its state accordingly. Finite automata is a recognizer for regular expressions. When a regular expression string is fed into finite
Python's design philosophy is documented in the Zen of Python. It consists of nineteen aphorisms such as: Beautiful is better than ugly Explicit is better than implicit Simple is better than complex Complex is better than complicated To obtain the complete Zen of Python ...
