C Analyzer & Reporter Modules Explained | C Project Masterclass Part 3

⚙️ Welcome back to the C Programming Project Masterclass!
In this third episode, we dive deep into the heart of our Log Analyzer v1.0 project — the 🧠 Analyzer and 🧾 Reporter modules.

You’ll learn how to design and implement the core logic that counts, aggregates, and formats log data efficiently in C using modular header files.

💡 What You’ll Learn

✅ Purpose of analyzer.h and reporter.h
✅ How to count log levels (INFO, WARN, ERROR)
✅ How to aggregate error messages by text
✅ Using structures and maps for error tracking
✅ Generating a Top-N Error Summary
✅ Formatting output cleanly in the CLI

⚙️ Modules Covered in This Video
🔍 Analyzer Module

Responsible for processing parsed log entries and storing statistics.

Example:

#ifndef ANALYZER_H
#define ANALYZER_H

#include "parser.h"

typedef struct {
unsigned long infoCount;
unsigned long warnCount;
unsigned long errorCount;
} LogStats;

void init_log_stats(LogStats *stats);
void update_log_stats(LogStats *stats, LogEntry entry);
void print_log_stats(const LogStats *stats);

#endif
Key Concepts 🧠

Updates log counters based on parsed log level

Stores aggregated error messages

Safe for large log files (line-by-line analysis)

🧾 Reporter Module

Formats and displays the final summary after analysis.

Example:

#ifndef REPORTER_H
#define REPORTER_H

#include "analyzer.h"

void print_summary_report(const LogStats *stats);
void print_top_errors(void);

#endif
Responsibilities 📊

Shows totals for INFO, WARN, ERROR

Displays Top-N error messages

Handles CLI flags (--errors-only, --top-errors N)

🧠 Why Analyzer & Reporter Are Crucial

Together they form the core engine of the Log Analyzer:

Analyzer → Processes and aggregates data

Reporter → Outputs results for the user
This clear separation keeps logic clean and maintainable.

🧱 Project Architecture So Far

✅ FileReader – Reads log files line-by-line
✅ Parser – Converts raw lines to structured entries
✅ Analyzer – Counts and aggregates errors
✅ Reporter – Displays summaries and Top errors
