🚀 Week 11: Mastering Operator Overloading, Templates & STL in C++

Apologies for the delay in posting this—exams kept me busy. Finally catching up!

This will be the last post of my C++ learning progress. Stay tuned for the next topic I'll pick!

This week, I delved deep into operator overloading, inheritance, virtual functions, templates, and STL containers in C++. Here's a quick recap of what I worked on during Days 104–110.

🔹 Day 71 – Operator Overloading

1. Time Incrementer – Overloaded ++ to adjust departure time
2. Matrix Math – Multiplication and transpose operations
3. Matrix Negator – Unary - to invert matrix elements

---

🔹 Day 72 – Inheritance & Virtual Functions

1. Population Growth Calculator – Virtual calcRate()
2. Time Format Converter – Conversion between hours, minutes, and seconds
3. Reservation Discount System – Age-based pricing

---

🔹 Day 73 – Abstract Classes & Use Cases

1. Meal Price Estimator – Polymorphism with calculatePrice()
2. Shop Inventory Manager – Item management using virtual functions
3. Experiment Analyzer – Analyzing experimental data with polymorphism

---

🔹 Day 74 – Practical Polymorphism

1. Item Cost Calculator – Discounts based on item type
2. Banking System – Inheritance for different account types
3. Vehicle Cost Tracker – Calculate travel time/cost across modes

---

🔹 Day 75 – Templates

1. Stack Handler – Operations for int and float types
2. URL Tracker – Indexing URLs with function templates
3. Laptop Model Manager – Track models using function templates

---

🔹 Day 76 – Smart Array Operations

1. Composite Number Filter – Remove primes from list
2. Array Max Finder – Find largest/second-largest elements
3. Odd Index Printer – Print elements at odd indices

---

🔹 Day 77 – STL & Template Utility Apps

1. Construction Inventory System – Update/display material info
2. STL List Handler – Sort/remove duplicates from std::list
3. Table Generator – Print multiplication table for an array element
