To start with C++ introduction you will need to have knowledge of syntax, a compiler, and a text editor to write the C++ code. There are many text editors and compilers. You can choose any of them. In this tutorial, we will learn more about how to start with the C++ programming language.
C++ Introduction: How To Get Started?
If you are a beginner and new to programming languages then for C++ language you might require the following things mentioned below.
- A text editor to write C++ Introduction and programs
- A compiler to translate the C++ code into a machine-understandable language
- Knowledge of C++ Syntaxes
- Introduction of C++ with Basics and Fundamentals of C++ Programming Language.
How To Install C++ IDE?
We can easily install the C++ IDE. In this C++ Introduction, we will learn how to install C++ IDE on our personal computers. A C++ IDE is used to edit the code and compile it for execution. Some of the popular IDEs are Visual Studio Code, Eclipse, Atom, Code:: Blocks, etc. Check the steps below to download the C++ IDE.
Note: We will learn to download the Visual Studio Code IDE on our devices.
- First, go to the official website of Visual Studio Code or you can also search for Visual Studio Code download.
- Now, you can either select the Download option directly or click on the website to redirect to the homepage of Visual Studio Code.
- Let us click on the Download option directly from the SERP page.
- Choose the download option based on your device specifications. You can check the specifications of your device from setting options on your device.
- Choose Windows, macOS, or Linux-based download based on your device.
- Click on the button to start downloading, once downloaded open the Visual Studio Code application.
- You can start your C++ coding by creating a “New File” or opening an existing file.
- You can set up the compiler based on your preference and download plugins, extensions and other features available on Visual Studio Code.
- Happy C++ Coding!
C++ Introduction: Hello World! Program On Compiler
Let us create our first C++ introduction file with the “Hello World!” program on our IDE. You have to click on File – > New -> Empty File and start writing the C++ program. You can choose the name for your first C++ introduction program as “myfirstprogram.cpp” and saveFile.
| #include <iostream>
using namespace std; int main () { cout << “Hello World!”; return 0; } |
The Visual Studio Code interface will look like the one given below. You can click on the Run button and start executing the program. In the output, you can see “Hello World!” displayed on the screen.
Output
You do not need to worry if you are not familiar with the different elements in the above code, we will learn more in C++ Tutorials.
How To Use Online Compilers At PW Skills?
There are many online compilers available for editing and executing Cpp code. You can easily start writing, editing, and executing C++ programs on online compilers.
You can get complete access to the PW Skills Lab online compiler when you enroll in the PW Skills Decode DSA with C++ Course.
Meanwhile, you can use online compilers like GDB compiler, Programiz, Google Collab, etc. The best part about online compilers is you do not have to download them on your local device, start using them online. Follow the steps to start the C++ introduction program on the GDB Compiler.
- Go to the GDB Compiler website and click on the first result of the SERP page.
- The following interface will appear with a C++ interface by default.
- You can choose the programming language you want to use or write your code.
- After selecting the programming language start editing your program and when done click on the “run” button on the top of the taskbar option.
- The program will execute in the terminal given below and you can see the output of your first program language, introduction.

C++ Introduction FAQ
Q1. What is C++ Programming Language?
Ans: C++ is a high-level, general-purpose programming language developed by Bjarne Stroustrup in the early 1980s. It extends the C programming language by introducing features like:
Object-Oriented Programming (OOP) (e.g., classes, inheritance).
Generic Programming (templates).
Low-Level Features for Performance Optimization.
Q2. What are the key features of C++?
Ans: Some of the important features of the C++ programming language are given below.
1. Object-oriented programming: Classes, objects, inheritance, polymorphism.
2. Low-Level Manipulation: Pointers, memory management.
3. Standard Template Library (STL): C++ consists of predefined functions and data structures like vectors, lists, and maps.
Performance Optimization: C++ programming provides direct hardware interaction and low-latency execution.
Compatibility: C++ programming language is backward compatible with C code.
Q3. What are the prerequisites for learning C++?
Ans: Some of the prerequisites of C++ introduction and programs are mentioned below.
1. Basic understanding of computers and programming logic.
2. Familiarity with another programming language like Python or C (optional but helpful).
3. Interest and familiarity with problem-solving and algorithmic thinking
Q4. What tools are needed to start with C++?
Ans: We will use Visual Studio Code to write and edit our C++ programming language. Some of the other tools needed to start C++ programming language are mentioned below.
1. Compiler: GCC, Clang, MSVC.
2. IDE/Text Editor: Visual Studio Code, Dev-C++, Code::Blocks, or CLion.
3. Debugger: Often integrated within the IDE.
