Syntax Analyser

Question 1
Marks : +2 | -2
Pass Ratio : 50%
By whom is the symbol table created?
Compiler
Interpreter
Assembler
None of the mentioned
Explanation:
Symbol table is created by the compiler which contains the list of lexemes or tokens.
Question 2
Marks : +2 | -2
Pass Ratio : 50%
Which phase of the compiler is Syntax Analysis?
First
Second
Third
None of the mentioned

It is Second Phase Of Compiler after Lexical Analyzer.
Question 3
Marks : +2 | -2
Pass Ratio : 50%
Which of the following system software resides in the main memory?
Text Editor
Assembler
Linker
Loader
Explanation:
Loader is used to loading programs.
Question 4
Marks : +2 | -2
Pass Ratio : 100%
Suppose One of the Operand is String and other is Integer then it does not throw error as it only checks whether there are two operands associated with ‘+’ or not.
True
False
Explanation:
Syntax analyser does not check the type of the operand.
Question 5
Marks : +2 | -2
Pass Ratio : 100%
What does a Syntactic Analyser do?
Maintain Symbol Table
Collect type of information
Create parse tree
None of the mentioned
Explanation:
Syntax analyzer will just create a parse tree. Semantic Analyzer checks the meaning of the string parsed.

Syntax Analysis
Syntax Directed Translation
Code generation
Explanation:
It is the function of Syntax directed translation.

Marks : +2 | -2
Pass Ratio : 50%
A compiler can check?
Logical Error
Syntax Error
Both Logical and Syntax Error
Not Logical and Syntax Error
Explanation:
No compiler can ever check logical errors.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
In Short Syntax Analysis Generates Parse Tree.
