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.
Example Program
The below code shows the simplest C++ program that you can run to print some text on the console screen.
C++
#include <iostream>
using namespace std;
int main() {
cout << "Hello World";
return 0;
}
C++ Fundamentals
This section guides you through the basic concepts of C++ programming. It covers topics that teaches you to write your first program, manage data, perform different operations and control the flow of the program.
C++ 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) in C++
This section covers key concepts of Object-Oriented Programming (OOP) in C++ such as classes, objects, encapsulation, inheritance, polymorphism, and abstraction.
C++ 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 in C++
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 in C++
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 C++
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.
