Parser is a compiler that is used to break the data into smaller elements coming from lexical analysis phase. A parser takes input in the form of sequence of tokens and produces output in the form of parse tree.Click to see full answer. Keeping this in view, what is top down parsing in compiler design?Top-down Parsing is a parsing technique that first looks at the highest level of the parse tree and works down the parse tree by using the rules of grammar while Bottom-up Parsing is a parsing technique that first looks at the lowest level of the parse tree and works up the parse tree by using the rules of grammar.Beside above, what is parsing of data? Parsing is the process of analyzing text made of a sequence of tokens to determine its grammatical structure with respect to a given (more or less) formal grammar. The parser then builds a data structure based on the tokens. Correspondingly, what is the role of parser in compiler design? Role of the parser : The parser obtains a string of tokens from the lexical analyzer and verifies that the string can be the grammar for the source language. It detects and reports any syntax errors and produces a parse tree from which intermediate code can be generated.What do you mean by parsing?Parsing. Parsing, syntax analysis, or syntactic analysis is the process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar. The term parsing comes from Latin pars (orationis), meaning part (of speech).
