Description: Syntax analysis is the core of the compiler. The role of grammatical analysis is to identify the word given by the lexical analysis of whether a given sequence of symbols of the grammar correct sentences. At present the right syntax analysis method commonly used top-down analysis and bottom-up analysis of two categories.
Determined by top-down approach, starting from the grammar symbols, consider how the current input symbol (word) only determine the choice of productions which replace the corresponding non-terminal symbol derived down. LL (1) grammar is a sure top-down analysis.
LL (1) the meaning is: the first one shows that top-down analysis of L from left to right scanning input string, the second L showed that the analysis process will be the most left-derivation, a show that just the right look can be a symbol deduced that the choice to decide how to produce what type (ie, rules) for derivation.
