C++ Deep Dive — Practice Repository

This repository contains my implementations, exercises, and notes from the Udemy course
Learn C++ Programming – Beginner to Advance – Deep Dive in C++ by Abdul Bari.

It demonstrates my progression through the core topics of C++ — from fundamental data types and control flow all the way to object-oriented programming, templates, STL, exceptions, and a capstone Banking System project.

📂 Repository Structure

• dataTypes/
  Covers C++ primitive types, variables, operators, expressions, enums, typedefs, and bitwise operations.

• Section_5_C++_Basics/
  Basics of writing C++ programs, precedence rules, conditional statements, loops, and control flow.

• Section_8_Arrays/
  Single- and multi-dimensional arrays, searching (linear, binary), sorting, and array-based algorithms.

• Section_10_Strings/
  C-style strings and std::string, string manipulation methods, iterators, substring operations, and parsing.

• Section_11_Functions/
  Function definitions, overloading, default arguments, templates, inline functions, recursion, and scope management.

• Section_12_13_OOPS/
  Core OOP concepts: classes, objects, constructors/destructors, operator overloading, encapsulation, and data hiding.

• Section_14_15_16_Inheritance/
  Inheritance models, constructor chaining, base-class pointers, polymorphism with virtual functions, and abstract classes.

• Section_17_Friends_Inner_Static/
  Friend functions/classes, static members, and nested/inner class usage.

• Section_18_ExceptionHandling/
  Exception handling with try/catch, throw mechanics, multiple catch blocks, and error safety.

• Section_19_Templates/
  Function and class templates for generic programming and type-safe reuse.

• Section_20_Constants_Preprocessor_Namespaces/
  Usage of const, macros, preprocessor directives, and organizing code with namespaces.

• Section_21_Streams_IO/
  Input/output streams, file handling, text vs binary I/O, and serialization.

• Section_23_STL/
  Standard Template Library: vectors, lists, stacks, queues, sets, maps, and algorithms.

• Final_Project/
  A simple Banking System console application that integrates OOP, exception handling, file I/O, and STL containers.

🚀 Skills Demonstrated

• Core C++ syntax and semantics (data types, loops, functions).
• Object-Oriented Programming (encapsulation, inheritance, polymorphism).
• Operator overloading, friend classes, and static/inner classes.
• Generic programming with templates.
• Robust programs with exception handling.
• File handling and streams (text & binary).
• Practical use of the STL (containers, algorithms, iterators).
• Application of C++11 features like lambdas and smart pointers (in relevant exercises).
• Building a complete project (Banking System) tying together all major concepts.

🛠️ Build & Run

Compile a single file

g++ -std=c++17 -Wall -Wextra Section_10_Strings/string_methods.cpp -o string_methods
./string_methods

📜 Notes

All code here is original practice I wrote while following the course.

The structure mirrors the course sections for easy navigation.

This repository acts both as a portfolio of C++ fundamentals and a reference library for future projects.
