💡 Hint

Common Mistakes

Confusing Lex with Yacc or Bison, which are parser generators.

Lex is a tool used to generate lexical analyzers, which break input text into tokens.

2fill in blank

medium

Complete the code to identify the tool used for syntax analysis.

Compiler Design

The tool used for syntax analysis or parsing in compiler construction is [1].

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up Lex and Yacc roles.

Yacc is a parser generator that helps analyze the syntax of the input based on grammar rules.

💡 Hint

Common Mistakes

Choosing Lex instead of Yacc for parser generation.

Yacc generates parsers from grammar rules, while Lex generates lexical analyzers.

4fill in blank

hard

Fill both blanks to complete the dictionary comprehension describing compiler tools.

Compiler Design

tools = {name: [1] for name, type in compiler_tools.items() if type [2] 'parser'}

Drag options to blanks, or click blank then click option'

Atype.upper()

Btype.lower()

C==

D!=

💡 Hint

Common Mistakes

Using '!=' instead of '==' causes wrong filtering.

This comprehension selects tools whose type exactly matches 'parser' and uses type.lower() as the value.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension filtering lexical tools with names in uppercase.

Compiler Design

lex_tools = [1]: [2].upper() for [3], t in compiler_tools.items() if t == 'lexical'

Drag options to blanks, or click blank then click option'

Aname

Dtype

💡 Hint

Common Mistakes

Using 'type' as a variable name shadows Python's built-in type() function.

The comprehension creates a dictionary with tool names as keys and their uppercase names as values, filtering only lexical tools.
