Build a complete, modern, fully functional educational web application called C Logic Lab for B.Tech Computer Science Engineering Semester 1 students learning C programming. Create a NEW website from scratch, not a modification of my old app. Make it responsive, beginner-friendly, and suitable for a college project. Use a clean modern UI with navy blue, white, and purple accents, a sidebar, dashboard, searchable lessons, and progress tracking.

CORE FEATURES:
1. Home dashboard with learning progress, modules, recent activity, and shortcuts.
2. Lessons containing detailed explanations, definitions, syntax, commented C examples, expected output, step-by-step dry runs, common mistakes, summaries, and previous/next navigation.
3. Include all 18 modules and topics listed below.
4. Each lesson must have beginner, intermediate, and advanced practice levels, with questions, hints, answer checking, explanations, and score tracking.
5. Topic-wise MCQ quizzes and a revision quiz with accurate scoring and explanations.
6. Code Tracing tool to step through code, showing variable values and output where feasible.
7. USER-ENTERED C CODE DEBUGGER: provide an editor where users can type or paste ANY C program, click Analyze Code, see errors and line numbers, read explanations, and receive corrected code or suggested fixes. Include Copy Code, Reset Editor, and Try Example buttons. Do not restrict debugging to fixed exercises or compare only against a predefined answer. Use a real compiler/parser/linter only if a safe, supported integration is available. Otherwise provide clearly labelled static analysis for common errors and disclose its limitations. Never claim all errors can be detected. Never execute arbitrary C code on the server without an isolated sandbox and resource limits. Do not require paid APIs.
8. Separate guided debugging challenges for missing punctuation, assignment versus comparison, off-by-one loop errors, uninitialized variables, arrays and other common mistakes. These are additional to the free-entry debugger.
9. Practice questions organized by topic and three difficulty levels in every lesson. Include coding problems, hints, test cases where feasible, explanations, and completion tracking.
10. Student progress dashboard showing completed lessons, quiz scores, practice levels, and topic strengths.
11. Teacher dashboard with clearly labelled demo data and a summary of learning activity.
12. Search, syllabus checklist, responsive mobile layout, and accessible navigation.

COMPLETE CURRICULUM — CREATE REAL LESSON CONTENT, NOT JUST HEADINGS:
Module 1: Introduction to C — history, features, applications, program structure, compilation process, algorithms, flowcharts, pseudocode, problem solving.
Module 2: C Fundamentals — character set, tokens, keywords, identifiers, constants, variables, data types, declarations, initialization, type conversion and casting.
Module 3: Operators and Expressions — arithmetic, relational, logical, assignment, increment/decrement, bitwise, conditional, sizeof, precedence and associativity.
Module 4: Input and Output — printf(), scanf(), format specifiers, escape sequences, character input/output.
Module 5: Decision Making — if, if-else, nested if, else-if ladder, switch, conditional operator.
Module 6: Loops — for, while, do-while, nested loops, break, continue, dry runs, common loop mistakes.
Module 7: Arrays — one-dimensional and two-dimensional arrays, initialization, traversal, searching, sorting, matrix operations.
Module 8: Strings — character arrays, declaration, initialization, input/output, null terminator, string handling functions, common string errors.
Module 9: Functions — declaration, definition, calling, parameters, return values, library functions, recursion, base and recursive cases, direct and indirect recursion, factorial, Fibonacci, recursive tracing, scope and lifetime of variables.
Module 10: Pointers — addresses, pointer declaration, dereferencing, pointer arithmetic, pointers with arrays and functions, common pointer errors.
Module 11: User-Defined Data Types — structures, nested structures, arrays of structures, unions, typedef, enumerations.
Module 12: Storage Classes — auto, static, extern, register, scope, lifetime and visibility.
Module 13: Preprocessor — #include, #define, macros, conditional compilation.
Module 14: File Handling — file pointers, opening/closing files, reading/writing, file modes, EOF, error handling and basic file operations.
Module 15: Dynamic Memory Allocation — malloc(), calloc(), realloc(), free(), NULL checks and memory management basics.
Module 16: Searching and Sorting — linear search, binary search, bubble sort, selection sort, insertion sort.
Module 17: Problem Solving — algorithms, flowcharts, dry runs, tracing, syntax/runtime/logic errors, debugging and testing.
Module 18: Practical Programming — pattern programs, number problems, arrays, matrices, strings, functions, recursion, pointers, structures and file-handling programs, case studies and mini-projects.

UNIVERSITY SYLLABUS:
Also ensure coverage of the supplied semester syllabus categories: Introduction to Programming and C Basics; Decision Making and Looping; Functions and Arrays; Pointers and Dynamic Concepts; Structures, Unions and File Handling, including command-line arguments; Problem Solving Applications, case studies, mini-projects, debugging, testing, and real-world applications. Ignore the supplied study-hour and percentage-weightage figures. Mark advanced or university-dependent topics as optional rather than claiming every university requires them.

LESSON FORMAT:
Every individual lesson should have a definition, detailed beginner-friendly explanation, syntax, at least one valid C example, expected output, line-by-line explanation, dry run where useful, common mistakes, a short summary, practice questions at beginner/intermediate/advanced levels, and MCQs with answers and explanations. Use accurate examples and do not invent compiler verification.

PRACTICE AND QUIZZES:
Each lesson must independently offer Beginner, Intermediate, and Advanced practice. Questions must match that lesson's topic. Provide hints, answer validation, explanations, and score updates. Use a reasonable initial question bank and make adding more questions straightforward. Do not use empty placeholder pages or repeat identical generic content for every lesson.

DATA AND FUNCTIONALITY:
Make buttons and navigation functional. Persist progress using available built-in storage or local browser storage if no backend is available. Do not pretend that demo teacher data is real student data. Do not require sign-in unless genuinely supported. Do not require paid AI APIs, paid databases, or paid services. Explain any feature that cannot work without an external service.

DESIGN:
Create a polished, modern, responsive learning platform with navy, white, and purple accents; a sidebar with Home, Lessons, Quizzes, Practice, Debugging, Code Tracing, Progress, Syllabus and Teacher Dashboard; searchable module cards; readable code blocks; and a beginner-friendly layout.

QUALITY CHECKS:
Test lesson navigation, code editor input, common debugging examples, hints, reset/copy buttons, quiz scoring, all three practice levels, progress persistence, recursion content, and mobile layout. Keep user-entered code separate from guided fixed challenges. The free-entry debugger must analyze the user's submitted code rather than only checking whether they reproduced a stored solution. Clearly distinguish static analysis from actual compilation and execution. Build the working application and show the preview. Do not merely return a plan or a mockup.
