What are the parsing techniques?

- Recursive Descent Parsing. Recursive descent is a top-down parsing technique that constructs the parse tree from the top and the input is read from left to right.
- Back-tracking.
- Predictive Parser.
- LL Parser.
- LL Parsing Algorithm.
- Shift-Reduce Parsing.
- LR Parser.
- LR Parsing Algorithm.
What are the grammar rules for expression parsing?
Set of expression parsing rules (called grammar) is as follows, Rule1: E → E + E Expression is the sum of two expressions Rule2: E → E * E Expression is the product of two express Rule3: E → number Expression is a simple number Rule4: + has less precedence than * + has less precedence than *
When do you use the term parsing in Computer Science?
Within computer science, the term is used in the analysis of computer languages, referring to the syntactic analysis of the input code into its component parts in order to facilitate the writing of compilers and interpreters. The term may also be used to describe a split or separation.
