C Fundamentals
- Why C & C++, and Your First Program — C (1972) is a small, fast, "close to the hardware" language — operating systems (Linux, Windows kernels), databases and embedded devices are written in it.
- Variables, Data Types & printf — C is statically typed: you must declare a variable's type before using it, and it cannot change.
- if / else, Loops & Conditions — Control flow decides which statements run.
- Functions & Pass-by-Value — A function is a named, reusable block of code: it has a return type, a name, a parameter list, and a body.
- Arrays & C Strings — An array is a fixed-size, contiguous block of elements of the same type: `int a[5];`.
- Pointers — the Heart of C — A pointer is a variable that stores the memory address of another variable.
- Structs — Grouping Related Data — A struct bundles several related variables (of possibly different types) into one named type — e.g.
- Dynamic Memory: malloc & free — So far arrays had a fixed size known at compile time.
C++ & OOP
- C++ Classes & Objects — C++ adds classes — a blueprint that bundles data (member variables) with the functions that operate on it (member functions / methods).
- Inheritance & Polymorphism — Inheritance lets a class reuse and extend another.
- The STL: vector, map & algorithms — The Standard Template Library (STL) is why competitive programmers love C++.
Who this C Cpp course is for
School and college students in India starting from zero, and anyone revising C Cpp for placements, board practicals or a project. There is no prerequisite beyond being able to type — the first lessons assume no programming background at all.
How to study this course
- Read the lesson, then run the example in the built-in editor before moving on — reading code is not the same as writing it.
- Try the practice task at the end of each lesson. Getting it wrong and fixing it is where the learning happens.
- When you are stuck, ask the free AI Tutor to explain that specific line rather than skipping ahead.
