Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which phase of the compiler is also known as Parser?
A
Code Optimization
B
Semantic Analysis
C
Syntax Analysis
D
Lexical Analysis
Explanation: 

Detailed explanation-1: -Syntax analysis or parsing is the second phase of a compiler.

Detailed explanation-2: -Syntax Analysis: Basically, in the second phase, it analyses the syntactical structure and inspects if the given input is correct or not in terms of programming syntax. It accepts tokens as input and provides a parse tree as output. It is also known as parsing in a compiler.

Detailed explanation-3: -Explanation: The phase of the compiler next to the lexical analysis phase is also known as Parser. Syntax analysis or parser accepts the tokens produced by the lexical analysis and gives the parse tree in the output.

Detailed explanation-4: -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).

Detailed explanation-5: -Syntax analysis is the second phase of compilation process. It takes tokens as input and generates a parse tree as output. In syntax analysis phase, the parser checks that the expression made by the tokens is syntactically correct or not.
