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
