What is the Difference Between C# and C++? Tabular Comparison

Let us imagine a situation – you are an aspiring programmer. We are as sure as we are about our existence that you are confused about which programming language do you need to make a beginning in.

The software world has plenty of languages when searching for a good programming language, and if you are a beginner, every language that begins with C appears the same. Yes, we are talking about C, C++, and C#. You would perhaps find all of them similar.

But wait – there is an intrinsic difference between each of those languages. Each among C#, C and C++ are targeted at different requirements and different application requirements.

And that is what we will be covering in today’s post – What is the difference between C# and C++ and which among them is the best for you.

What is C++?

C++ is a programming language that comes with similar features as on C. In fact, it was the language that introduced the concept of Class and Objects. It shares most of its features and options with other programming languages such as C and Simula67.

The language was developed by Bjarne Stroustrup. In essence, it has been considered to be the hybrid language as you can write a program both in C and C++ style. C++ as a language comes with the features of both high and low-level languages. This is precisely what would make it one of the best intermediate-level languages.

What is C#?

Pronounced as C Sharp, C# is one of the popular object-oriented programming languages. The language is developed by Microsoft and has been receiving consistent updates. In fact, C# is the language that helps run the Microsoft .NET program.

The C# programming language offers you access to wonderful features as the best options for strong typing, imperative, declarative, object-oriented, and component-oriented programming. Once again, the language is primarily influenced by its predecessors C and C++. The language was developed by Anders Hejlsberg.

How do C++ and C# Compare with One Another? Tabular Comparison

Before we can discuss C++ and C# and compare their features and functionalities, we will compare the two languages based on the differences between them in a tabular format.

What is the Difference Between C# and C++

How Similar is C# to C++ ?

Well, there are not many similarities between C# and C++. At the minute level, both C++ and C# may have a few minor similar features. One of the common features offered by C++ and C# is both of them are object-oriented languages.

You can use both C++ and C# come with the ability to build both desktop and web applications. C# is more based on C, and C# is more close to Java. However, you may ideally come across the similar syntax between C++and C#.

The significant similarities between C# and C++ can be summed up as here below:

  • Both of them come with the garbage collection feature. Of course, C++ does not have it out of the box, but can be allocated.
  • Both of them come with strict compiler conditions.
  • Both C++ and C# come with considerable API and documentation support.
  • Both languages are capable of performing reflections.
  • They can handle exceptions in a better manner.

When Was C# Created?

Like we have already observed, C# was developed by Anders Hejlsberg. He came up with a team that was indulged in the creation of a new language. The development of the language began in 1999, and the language was initially labeled as Cool. The project was finalized in 2000.

The language was finally unveiled at the Professional Development Conference, and it was here that the language was finally christened as C#. The C# programming language known as C Hash or C Sharp has been developed based on C and taken ahead from there.

When was C++ Made?

C++ owes its origin to Bjarne Stroustrup, who was an employee with AT & T Bell Laboratories. He was quite fond of C and Simula67. He thought of combining the best features of both languages and arrived at the wonderful language in the form of C++.

C++ was standardized in 1998. The language was created with the aim of getting access to the best features on C along with an option for the best object-oriented programming functionalities.

The language has been one of the oldest languages and has been quite popular in the realm of healthcare and finance industries and perhaps would continue to rule the roost in the years to come. The language was initially named as “C with Classes”.

Should I Learn C# or C++?

Well, C++ and C# cater to the two different categories of developers. They do have different skill sets. That would mean which among C++ and C# should you choose is a matter of the skill sets you want to achieve.

The rule of thumb should be that if you are into web and application development, you would better have access to a high-level language and by all comparison, C# is a more of a high-level language compared to C++ which can at the most considered to be the intermediate programming language. As we are aware, most of the web development requirements focus on the knowledge of the .NET platform, and as such C# can definitely be the best options you would want to go with.

C++ does have a wide range of options in the realm of targeted applications and support for platforms but does not have a wide developer pool when you think of web and desktop applications. It can be suitable for those areas which need low-level processing. C++ can be helpful in the creation of faster applications on the server-side, but may not be cost-efficient.

C# can be quite slow as it has to compile the program with different libraries. It can be the right option when you are looking at the programs where the performance in terms of speed does not matter much. C++ provides you with a faster performance but does not provide the same degree of efficiency as on C#.

Ideally speaking, it may be a good idea to post your project and ask the developer community to share their views on which programming language would be better suited for your requirements. You should get better suggestions from the developer communities.

C# for C++ Programmers – Would it be Easier?

C# is all about high-level component-oriented language. This is in sharp contrast with C++ where you would have access to a low-level object-oriented programming language experience. Moving from platform-neutral language to a managed language mode will indeed be a huge task in itself.

Moving from C++ to C# would make you leave control that you so far enjoyed. C++ provides you with a huge control over the creation and layout of your objects. When you move to C#, you lose that level of control.

C++ and C# may have similar features in a few ways. The syntax remains almost identical across both languages. Both of them are object-oriented. That would mean if you are proficient in C++, it should not take you more than a few days to learn C#. In fact, you should be able to create code within a span of just around a couple of days. If you are looking at the option of becoming proficient, it should not take more than a few weeks to begin your professional journey.

The two languages come with a  different set of standard and third-party libraries. Now that you would be using them quite often for a wide range of projects, it would ideally take a while before you can get adjusted. That should not mean they are tough to handle. The only issue would be that you would take time to find the best library or tool.

Yet another difficulty you are likely to face would be that C# has a few constructs that you would not be able to find on C++. Of course, you would not need them right away for all your tasks, but they offer a better degree of functionality. Until the time you learn these constructs, you would not be able to reach the proficiency levels achieved by your fellow programmers in C#.

Is C# Easier Than C++?

Well, C# is a more accessible and simpler language to learn. In fact, it is a small language when you compare it to C++, but comes with a huge library. C++, on the other hand, is a larger language with a considerably smaller library. Learning C# should be rather easy when you compare it to learning C++, but implementing your knowledge in programming is a huge task.

Creating simpler applications with C# should be much easy and simple. But, if you need to use com objects and all the other important aspects, it suddenly gets rather difficult.

Differences Between C# and C++

Well, we have already gone through a few key aspects of C++ and C# and found how do they differ. We will now make a comparison based on a few key parameters.


C# does have to compile with the help of a wide range of libraries. This makes it a little slower when it comes to performance. That would make it lose out in terms of performance to C++.

The major attributes that contribute to lower performance on C#, when compared to C++ can be better understood here:

  • C# has a lot of libraries and other overheads before it can begin compilation
  • Any high-level language is typically slower than a low-level language. That would invariably man C# is slower than C++.
  • C# does have an additional execution step called JIT compilation. This turns C# a little slower
  • The optimization level offered by C# is much lower than that on C++

Most of the experts believe that the performance level of C# and C++ are not much of a higher degree and are quite minimal. They would consider the differences much exaggerated.


This can be a rather tricky situation. If you are looking for the speedy applications, you would want to turn to C++. An excellent example of the speedier applications with C++ would be games, browsers, or operating systems.

On the other hand, C# may not be the right choice for applications that need faster performance. They would suit the application areas such as Windows software and application development. In other words, the backend applications would work better when created with C#.

In Conclusion

C++ is a programming language primarily used for application areas that focus more on performance than on efficiency. C#, on the other hand, can be one of the excellent options for beginners and can be used for a wide range of applications such as web-based, mobile, and desktop applications with ease.

We assume the overview of the differences and similarities offered by the two programming languages as in the above discussion should ideally be useful for you in deciding the right language for your individual needs. Check the best features offered by each of the languages and pick the best among them.
