Beginner to Advanced 10 Weeks 10 Modules Online / Classroom Inventory Management System

Course overview

C++ is a general-purpose programming language used for application development, systems software, games, embedded work, performance-sensitive tools, and many other technical domains.

This course begins with syntax, functions, control flow, and object-oriented design. It then introduces inheritance, polymorphism, templates, STL containers, algorithms, iterators, lambdas, exceptions, files, and modern resource-management practices.

The final project connects those topics through an inventory-management application with clear data models, operations, persistence-ready structure, validation, and documentation.

Modern C++ is not only about pointers and manual memory. Good C++ design also uses clear ownership, RAII, standard-library components, appropriate abstractions, testing, and a build process that another developer can reproduce.

Prerequisites

Basic programming logic is helpful but not mandatory. Learners should be comfortable reading instructions, using a code editor, and running commands.

  • Basic computer and file-management knowledge.
  • Willingness to practice syntax through small programs.
  • Basic logic involving conditions and repetition is helpful.
  • Basic terminal knowledge is recommended.
  • Prior C experience is useful but not required.
  • Mathematics beyond basic arithmetic is not required for the core course.

Readiness activity

Write a small program that reads product names and quantities, calculates a total count, and prints a summary. Then identify one invalid input and explain how the program should respond.

If you want a simpler first programming language, review the C Programming course before beginning this course.

Curriculum outline

The ten-module outline progresses from fundamentals to a modular application. The exact language standard and compiler version should be confirmed before delivery.

01

C++ fundamentals and development setup

Learn how C++ source code becomes an executable and build a reliable starting workflow.

  • Source files, headers, compilation, and linking.
  • Compiler flags and readable compiler output.
  • Variables, constants, literals, and primitive types.
  • Input/output with streams.
  • Namespaces and basic standard-library usage.
  • Comments, naming, formatting, and code organization.

Practice: Create a console program that reads product information, validates basic values, and prints a formatted summary.

02

Control flow, functions, and program structure

Break problems into understandable operations and control how programs make decisions.

  • Conditional statements and nested decisions.
  • For, while, and range-based loops.
  • Function declarations, definitions, and return values.
  • Parameters, references, const parameters, and scope.
  • Function overloading and default arguments.
  • Recursion and when iteration may be clearer.
  • Header files and separate compilation concepts.

Practice: Build menu-driven functions for adding, finding, updating, and displaying inventory items.

03

Classes, objects, and encapsulation

Represent application concepts as objects with clear state, behavior, and access boundaries.

  • Classes, objects, data members, and member functions.
  • Public, private, and protected access.
  • Constructors, destructors, and initialization.
  • Member initializer lists.
  • Const member functions.
  • Getters, setters, and validation boundaries.
  • Composition and single-responsibility design.

  • Project folders, headers, source files, and libraries.
  • CMakeLists.txt and cross-platform build concepts.
  • Out-of-source builds and build directories.
  • Compiler warnings and debugging workflow.
  • Unit-test concepts and testable design.

Capstone project

Inventory Management System

Create a console-based inventory application for managing products, quantities, categories, prices, and stock changes. Use the project to demonstrate object-oriented design, STL usage, input validation, file persistence, and modular organization.

Core project requirements

  • Add products with unique identifiers.
  • Display products in a readable table or report.
  • Search by identifier, name, or category.
  • Update product quantities and prices.
  • Record stock additions and removals.
  • Report low-stock products.
  • Reject invalid quantities and duplicate identifiers.
  • Save and reload data from a file.
  • Separate data models, services, and user interaction.
  • Document build, run, test, and usage instructions.

Quality requirements

  • Use meaningful names and consistent formatting.
  • Keep validation close to the relevant domain operation.
  • Use standard-library containers where appropriate.
  • Explain ownership and resource-lifetime decisions.
  • Handle missing files and malformed records clearly.
  • Add tests for normal cases and important edge cases.
  • Build the project from a clean build directory.
  • Record known limitations and possible extensions.

Optional extensions

Add category reports, CSV import and export, a transaction history, a database-ready repository interface, a command-line argument parser, or a basic multi-user permission model. Add one extension at a time and test its effect on the existing design.

The capstone is an educational application. It should demonstrate design and programming skills, but it is not automatically production-ready without security, data protection, deployment, and operational review.

Suggested project structure

Use separate headers, source files, tests, and documentation so the project remains understandable as features are added.

cpp-inventory-project/
├── CMakeLists.txt
├── include/
│   ├── Product.hpp
│   ├── Inventory.hpp
│   └── Storage.hpp
├── src/
│   ├── Product.cpp

├── data/
│   └── sample-inventory.txt
├── docs/

│   └── test-checklist.md
├── README.md
└── .gitignore

The exact structure may differ. The important goal is to separate interface declarations, implementation, tests, sample data, and project documentation.

Modern C++ design practices

The course introduces modern practices gradually. Apply them when they make ownership, readability, safety, and maintenance clearer.

Ownership

Prefer clear lifetime rules

Know which object owns a resource, how long it lives, and what happens when operations fail.

RAII

Pair acquisition with cleanup

Use object lifetimes to manage files, locks, memory, and other resources safely.

STL

Use standard components

Prefer tested containers and algorithms when they express the problem clearly.

Const

Communicate what changes

Use const-correctness to make interfaces easier to understand and protect values from accidental changes.

Testing

Test behavior, not implementation details

Check public behavior, validation, errors, and important domain rules.

Clarity

Choose simple abstractions

Avoid adding templates or inheritance when a smaller, clearer design solves the problem.

Smart pointers such as unique ownership and shared ownership types are tools for expressing lifetime decisions; they are not a substitute for understanding ownership. [91][93]
