Syntax Tree

Explanation:
Detailed explanation-1: -A syntax analyzer or parser takes the input from a lexical analyzer in the form of token streams. The parser analyzes the source code (token stream) against the production rules to detect any errors in the code. The output of this phase is a parse tree.
Detailed explanation-2: -The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code. If the lexical analyzer finds a token invalid, it generates an error. The lexical analyzer works closely with the syntax analyzer.
Detailed explanation-3: -What is the output of lexical analyzer? Explanation: A lexical analyzer coverts character sequences to set of tokens.
