Syntax Analysis

Semantic Analysis

Lexical Analysis

Optimization Phase

Generates machine code directly

Translates the code into assembly language

Checks syntax, structure, and semantics of the code.

Optimizes the code for better performance

Syntax Analysis

Semantic Analysis

Code Generation

Lexical Analysis

To introduce bugs in the compiled code

To improve the efficiency of the generated code.

To slow down the compilation process

To increase the size of the generated code

The compiler crashes and shuts down when encountering syntax errors

The compiler automatically corrects syntax errors without any notification

The compiler stops the compilation process and displays an error message indicating the location and type of syntax error.

The compiler ignores syntax errors and proceeds with the compilation process

Create new programming languages

Debug software applications

Optimize computer performance

Translate source code into machine code

A token is a software program that analyzes the syntax of the source code.

A token is a categorized group of characters that represent a unit of meaning in the source code.

A token is a tool used to format the source code for readability.

A token is a type of cryptocurrency used for transactions in source code.

To analyze the input code based on grammar rules and create a parse tree or abstract syntax tree.

To optimize the code for better performance

To execute the code line by line

To generate machine code directly

Static semantics are checked at compile time, while dynamic semantics are checked at runtime.

Static semantics are only relevant for interpreted languages, while dynamic semantics are only relevant for compiled languages.

Static semantics are checked at runtime, while dynamic semantics are checked at compile time.

Static semantics are related to syntax errors, while dynamic semantics are related to logical errors.

Optimize the code for better performance

Translate intermediate representation into target machine code or another high-level language

Generate pseudocode for debugging purposes

Create a graphical user interface for the compiler

Common subexpression elimination, loop unrolling, dead code elimination, etc.

Memory bloating, eliminate lexical errors

Function wrapping, eliminate grammar errors

Variable folding, type checking errors

During compilation, the compiler generates error messages pointing out the specific lines of code where the runtime errors occur.

The compiler ignores runtime errors

Runtime errors are reported after the program execution

Runtime errors are fixed automatically by the compiler

Syntax errors

Syntax errors, Semantic errors, Logical errors

Runtime errors

Compilation errors

A lexer is a program that compiles code.

A lexer is a program that breaks input text into tokens.

A lexer is a program that optimizes database queries.

A lexer is a program that generates random text.

To visualize the execution flow of the program

To optimize the code for better performance

To check for runtime errors in the code

To represent the syntactic structure of the input code according to the grammar rules.

Semantic analysis is only important for debugging purposes after compilation.

Semantic analysis is used to optimize the compilation process for faster execution.

Semantic analysis ensures code readability by adding comments throughout the code.

Semantic analysis ensures the code's correctness by checking for logical errors, type mismatches, and enforcing language-specific rules.

They are used for creating graphical user interfaces.

They are used for defining tokens and grammar rules for lexical and syntax analysis.

They are used for optimizing code generation.

They are used for debugging runtime errors.

It stores information about the variables, functions, and their attributes in the source code.

It generates machine code directly from the source code.

It optimizes the code for better performance.

It checks for syntax errors in the source code.

To ensure that variables are declared before use and have the correct data type.

To optimize the code for better performance.

To generate machine code directly.

To create graphical user interfaces.
