C++ Programming Language

Last Updated : 13 Oct, 2025

C++ is a programming language known for its fast speed, low level memory management and is often taught as first programming language.

C++ is used in making operating systems, embedded systems, graphical user interfaces and nowadays in High Frequency Trading (HFT) systems.
Supports both low-level and high-level features such as manual memory management and Object Oriented Programming respectively.
Syntax similarity with C, Java, and C# makes it easier to switch languages.
Provides one of the fastest execution speeds among high level languages, which can be a deciding factor in Competitive Programming or high-performance applications.

Function

Functions allow users to divide the program into multiple blocks each performing a specific task. This section teaches you how to work with functions to write a modular and reusable code.

Compound Data Types

Compound data types are created from the built-in data types. This section guides you through important compound data types such as array, strings, pointer and structures that helps in managing complex real-world data.

Dynamic Memory Management

C++ allows the low-level memory manipulation using pointers and dynamic memory allocation/deallocation operators. This section guides you through the basis of dynamic memory management.

Object Oriented Programming (OOP)

This section covers key concepts of Object-Oriented Programming (OOP) in C++ such as classes, objects, encapsulation, inheritance, polymorphism, and abstraction.

Standard Template Library (STL)

This section covers Standard Template Library (STL) which is an in-built library that provides a set of commonly used data structures such as vectors, lists, stacks, queues, maps, etc. and algorithms that enhance productivity and performance.

Exception Handling

Exception handling are the techniques to handle runtime errors efficiently. This section covers how to handle exceptions to prevent crashes and improve the reliability of applications.

File Handling

File handling allows programs to store and retrieve data from files. This section introduces file handling in C++ using streams. It covers reading from and writing to files using streams.

Advanced Concepts

This section covers advanced concepts in C++ such as move preprocessor, multithreading, etc. Mastering these topics allows developers to write efficient, high-performance C++ applications.
