C++
Input
Today, we're diving into the world of C++, a widely-used programming language known for its power and efficiency. C++ is an extension of the C programming language, offering object-oriented features and other enhancements. This aiMOOC will guide you through the essentials of C++, from basic syntax to advanced concepts.
Introduction to C++
C++ is a high-level programming language that was developed by Bjarne Stroustrup at Bell Labs in the early 1980s. It's widely used for system/software development, game development, and in embedded systems. The language provides a rich set of features including object-oriented programming, templates, and exception handling.
Basic Syntax and Structure
In C++, a program is made up of functions and variables. The 'main' function is the entry point of every C++ program. Basic syntax includes the use of semicolons (;) to terminate statements and curly braces ({}) to define the scope of functions and control structures.
- C++ Data Types: Integers, floats, characters, and more.
- C++ Operators: Arithmetic, relational, and logical operators.
- Control Structures in C++: If, while, for loops, and switch cases.
Object-Oriented Programming (OOP)
C++ is known for its support of object-oriented programming, which includes concepts like classes, objects, inheritance, polymorphism, and encapsulation.
- Classes and Objects in C++: Understanding the blueprint and instances.
- Inheritance in C++: Base and derived classes.
- Polymorphism in C++: Compile-time and run-time polymorphism.
Advanced Topics
C++ also includes advanced topics that are essential for high-performance and efficient applications.
- Templates in C++: Generic programming with template classes and functions.
- Exception Handling in C++: Try, catch, and throw statements.
- STL in C++: Standard Template Library components like vectors, maps, and algorithms.

Encapsulation | Hiding internal state and requiring all interaction to be performed through an object's methods |
Namespace | A declarative region that provides a scope to the identifiers inside it |
Template | A feature of C++ that allows functions and classes to operate with generic types |
Algorithm | A step-by-step procedure for calculations, data processing, and automated reasoning |
Vector | A dynamic array in the Standard Template Library |
Exception | An event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions |
