Learn C++ for Kids
C++ (pronounced “see plus plus”) is one of the most popular computer programming languages in the world. It’s used to develop many things, from fun video games to major operating systems like Microsoft Windows and Apple’s iOS.
Today, we’re going to take you on a programming journey! You’ll learn the basic concepts of C++ for kids, as well as know how to write your first C++ program.

Why C++?
It’s never too early to learn a coding language!
C++ programming language opens up a whole new world for kids. From web design to web pages to game development, an 8-year-old or older can get a head start. Learning the tools of today can prepare a kid for the careers and hobbies of the future!
Along with creative coding, C++ develops problem-solving skills and a love for computer science. It also helps children learn good programming habits. This encourages them to start building their own games, websites, and more!

Another great starting point, along with this tutorial, is the Sterling Children’s board book C++ for Kids (Code Babies). The children’s book can be found on Amazon Books and other book retailers. It’s a fun, visually based introduction!
C++ vs. Java vs. Python
When it comes to learning your first text-based coding language, there are three popular picks: C++, Java, and Python.
All three are object-oriented programming (OOP) languages. This means they use “objects” to stand for data, which makes them faster & easier to use than functional languages.
Each language works differently and offers its own benefits. Let’s take a look!
Python
Python uses clear, understandable syntax—the set of rules which tells the computer how to read code—that makes it easier to focus on logic practice instead of a ton of details.
We often recommend learning Python first before jumping to Java, as the syntax is more user-friendly. It’s also generally easier to learn than Java.
Python is great for exploring data, building websites, and game development!
Java
Java is a general-purpose language that runs on pretty much any type of device. It’s the top choice for Android games and apps. This is because it offers powerful development tools made specifically for the popular mobile operating system.
C++
C++ programming language is highly versatile, making it great for a wide range of goals. The language is welcoming, practical, and allows kids to easily share concepts with other kids. It also gives programmers more freedom to do what they want.
C++ offers high performance and exact control. Applications range from video games to software to even artificial intelligence!
Keep in mind that no language is better than another language. Each one excels in its own way. The key is learning them and finding the right fit!
C++ Programming Concepts
Before we show you how to write your first C++ program, let’s take a look at the main programming concepts and terms. This will make coding a lot easier to understand!
Container: This is an object that contains other objects (known as elements). Each container handles the storage memory for and access to its elements.Compiler: A utility program that transforms your code into executable files.Function: A set of statements that, as a group, perform a specific task.IDE: Short for Integrated Development Environment, an IDE is an application for building software. In other words, it helps you write your code.Standard Library: The C++ Standard Library offers a multitude of generic containers and functions written in the core language.Syntax: As mentioned already, this is the set of rules for symbols, spelling, and grammar. This tells the device how to read your code.Template: Allows you to create classes or functions that work with different data types.Text editor: A program that lets you enter, change, store, and (typically) print plain text.Variable: This represents the name (or basic unit) given to a memory location.
First C++ Program (Hello World!)
Now, let’s get hands-on!
C++ is a powerful & complex computer language, but don’t be nervous! Learning C++ isn’t as scary as it might look. It can be broken down into 3 simple steps:
- Understand the basic concepts and terms
- Write your program in a text editor.
- Compile your program in a compiler or online IDE.
For today’s example, we’ll make a “Hello World” program. This is one of the simplest ways to learn C++. This will eventually make your screen display “Hello World.”

Use the above code to make your own!
Now, let’s break down what each line and term means:
// First C++ program to display "Hello World": A line that uses ‘//’ at the beginning is called a comment line. This doesn’t have any programming logic. It’s used to display additional info that the compiler simply skips over to the next line of code.
#include<iostream>: Lines that start with ‘#’ is called a directive. ‘#include’ tells the compiler to include a certain file (to preprocess the information). In this case, this tells it to include the standard iostream file.
namespace std: A namespace is used in C++ to organize code into logical groups. In the program, you can’t have functions, variables, and so on with the same name. This helps avoid any conflicts. In this case, ‘std’ is an abbreviation for standard.
int main (): This line is used to declare a function, which is made up of a set of statements needed to perform a certain task. The ‘main ()’ is necessary for any C++ program to run properly (regardless of location in the program).
{ and }: The ‘{‘ symbol stands for the start of the main function, while the ‘}’ symbol indicates the end of the main statement. All the code in between these brackets represents the main function.
std::cout<<“Hello World”;: This line, also known as a statement, tells the compiler to display a message. In this case, our first message is “Hello World.” The code after ‘<<‘ is what is displayed later on the screen.
Reason for Indentation: This first program is quite simple, only containing a few lines of code. But as complexity grows, you’ll deal with a lot more lines. Indentations help to make it easier to read. This helps to reduce the chance of errors.
return 0;: This is another statement. It’s used to return the value from the function (as well as signify that the function is finished).
And there you go! You just learned how to write your very first program. This is a simple way to build a solid foundation.
C++ can be tricky at first. A single typo can keep a program from running properly. But with practice (and continued learning), you’ll get the swing of things!
Welcome to C++! Now Keep Learning
We hope you’ve enjoyed learning about the basics of C++!
With this newfound knowledge, a coder age 8+ can confidently dive into the world of C++. Kids coding basics can lead to more advanced learning, opening up doors to game programming, web design, Android development, and much more!
