C++ Programming Tutorial¶
Recommended order: C++ roadmap -> Foundations -> OOP -> STL -> Templates -> Modern C++
Best for: Beginners, GSEB/CBSE std-12, BCA/MCA students, competitive programmers
Prerequisites: Basic understanding of C or any programming language is helpful
C++ combines the power of C with object-oriented programming. It is used in game development, operating systems, competitive programming, and high-performance applications. This roadmap takes you from zero to modern C++ developer.
What you will learn¶
Introduction
Learn C++ history, differences from C, and set up your IDE (VS Code + GCC / Dev-C++).
Foundations
Master variables, data types, cin/cout, type casting, and all C++ operators.
Control Flow
Control program execution with conditionals, while/for loops, break, and continue.
Functions
Write and overload functions, use default arguments, references, and inline functions.
Arrays & Strings
Use C-style arrays, std::string, and std::vector — C++'s dynamic array.
Object-Oriented Programming
The heart of C++ — classes, objects, constructors, inheritance, and virtual functions.
Pointers & References
Go deep into memory management with pointers, references, new/delete, and smart pointers.
STL (Standard Template Library)
Use C++'s powerful built-in containers and algorithms — vector, map, set, sort, find.
Modern C++ (C++11/17/20)
Learn modern C++ features: auto, lambda expressions, range-based for, move semantics.
Exception Handling
Handle runtime errors gracefully with try-catch blocks and custom exception classes.
File Handling
Read and write files with C++ streams — text files, binary files, and CSV processing.
