Although there are numerous programming languages available in the market to work on, C++ has never lost its charm since its inception and still has a strong impact on the development world. As per the reports, C++ comes under a few top programming languages across the world. Alike the C programming language, C++ also makes it easier for you to understand the underlying architecture of programming, although it also supports other additional features such as object-oriented programming, exception handling, etc. Moreover, various IT giants Google, Amazon, Microsoft, etc. offer numerous career opportunities to C++ professionals, hence you’re strongly recommended to give it a try and start to learn C++ Programming

What is C++

C++, developed by Bjarne Stroustrup, is a general-purpose programming language and is considered an advanced version of the C programming language. It offers rich library support in the form of a Standard Template Library. The language is widely used in various GUI platforms, Cloud/Distributed Systems, Operating Systems, real-time simulations, etc. Moreover, as C++ is an object-oriented programming language, it allows you to implement real-time problems through OOPS concepts. Here in this article, let’s discuss a thorough curriculum or roadmap that one should follow to learn C++ Language in 20 days!

Hurry Up! beginners, start your C++ journey and strengthen your programming language skills with GeeksforGeeks C++ Programming Foundation – Self Paced course mentored by Sandeep Jain.

C++ Programming Roadmap: A 20-Day Curriculum!

We have developed a solid understanding of what C++ is, and now it’s time for us to head straight to our 20-day roadmap. Whether you are a beginner or an expert, following the roadmap will lead to an increase in your knowledge of C++. This roadmap provides a structured approach, covering essential topics to give you a solid foundation in C++. Let us begin with the roadmap. 

1. Introduction to C++ Programming (Day: 1)

Needless to say, you’re required to start learning C++ programming language with the introduction and fundamentals of the language. You need to understand the features of the C++ language, and what are its applications. Furthermore, you’re required to know how to set up an environment to compile & run your C++ program. You can create your first C++ program as well for more clarification of the fundamentals. Meanwhile, you can explore several other related topics such as the difference b/w C & C++, C++ vs JAVA, etc.

2. Learn DataTypes, Variables & Operators (Day: 2-3)

Now you need to know about the building blocks of C++ programmingDataTypes, Variables & Operators. You need to get a thorough understanding of data types and how they are used, what are variables, how they are declared and initialized, the use of operators in C++, etc. It will help you to get familiar with the basic structure and syntax of C++ programming. There are several other topics also to be considered here such as Reference Variables, Operator Overloading, Optional Parameters, and others.

3. Learn Conditional & Control Statements (Day: 4-5)

Okay, now move to the control flow statements of the C++ programming language. Precisely, control flow statements concerned with the concepts like repeated execution of a block of statements – Loops, execution of code based on decision – Decision-Making Statements, etc. You need to cover these concepts thoroughly such as all types of loops like For Loop, While Loop, Do While loop, etc. and similarly all decision-making statements like if, if..else, nested if, etc. There are several other topics as well that concern with the control flow statements in C++ programming such as Jump Statements, Switch Statements, etc.

4. Understand Arrays, Strings & Pointers in C++ (Day: 6-8)

Once you’ll get done with the datatypes, variables, and other topics, now you’re required to understand the Arrays & Strings concepts in C++. An Array in C++ is used to store similar types of elements and Strings are used to store text or sequence of characters. Moreover, you need to learn about Pointers as well that is used for storing the address of another variable. Also, there are several other crucial topics such as Namespaces, Wild Pointers in C++, etc. that can be considered.

5. Go Through Functions & OOPs Concepts in C++ (Day: 9-12)

Now, it comes the most crucial part of the C++ programming journey: Functions & OOPS Concepts in C++. You need to know about the Functions in C++ which is a set of statements that is created to perform specific tasks. You have to learn about function declaration, function overloading, and other topics that concern with functions in C++. Meanwhile, you’re required to understand the Object-Oriented programming nature of C++ in-depth with various concepts such as Class and Objects, Inheritance, Polymorphism, Abstraction, and Encapsulation, etc.

6. Learn I/O Streams, Dynamic Memory, & STL in C++ (Day: 13-16)

Okay, let’s dive deeper into the world of C programming. Now, you’re required to understand several underlying concepts such as I/O Streams & File Handling in C++, Dynamic memory allocation in C/C++, etc. You’re also required to look upon Standard Template Library (STL) in C++ which a renowned feature of the language. In general, STL in C++ is a set of C++ template classes that provide general programming data structures and functions like stacks, arrays, etc. Moreover, you must have the knowledge of template classes to work on STL in C++.

7. Understand Exception Handling, Signal Handling & Multithreading in C++ (Day: 17-20)

Furthermore, you’re required to fetch up the things with some more advanced topics like Exception Handling, Signal Handling, Multithreading in C++, etc. In short, Exception Handlings tends to deal with the code that can throw an exception or error and Signal Handling concerns with the Signals which force an OS to stop its in-progress task and address the task for which the interrupt has been sent. Moreover, you’re required to use POSIX Threads for multithreading in C++.


Learning C++ can be a great asset for anyone interested in programming. The language, with its roots in C, offers a solid foundation, additionally including modern features like object-oriented programming. So this is a 20-day curriculum for everyone who wants to learn and make it big in C++ programming. The 20-day roadmap covers essential topics from basic syntax and control flow to advanced concepts such as OOP, memory management, and multithreading. After following the above-mentioned roadmap, you can also opt to build several minor and major projects to enhance your skills and gain more exposure to C++ programming. Hence, take some time from your schedule for the next 20 days and start to learn C++ with great dedication and consistency!!
