In this article, you will be learning about 6 Advantages and Disadvantages of C++ | Drawbacks & Benefits of C++. Through this post, you will know the pros and cons of using C++.
Let's get started,
Advantages of C++
1. Performance
Since C++ is a compiler based programming language, it is comparatively faster. During the program execution, there is no requirement to install special runtime. This type of fast execution makes it easy to create complicated programs even with complex GUIs.
2. Platform Compatibility
C++ is completely platform independent. So developers need not to be worried about platform compatibility. While using a single code base, the programs can run on multiple operating systems. For an example, when a program is developed for Windows OS, the same program can be reused in Linux without any changes to the original code. This is especially beneficial for applications that targets different operating system.
3. Memory Management
C++ supports the function of Dynamic Memory Allocation (DMA). It eliminates the usage of Garbage Collector. Hence, the management of the memory completely lies on the programmer. The users are allowed to allocate or reallocate memory as per the requirement.
4. Multi-Paradigm
C++ follows three paradigm approaches known as Generic, Imperative and Object-Oriented. Therefore, we can say it is a multi-paradigm programming language. Which means that it will supports different paradigms. Paradigms are nothing but the planning that takes place before programming an application. The planning involves logic, style and the approach.Â
5. Scalability
If there is any application that is resource intensive, C++ scales them up accordingly. i.e. the programs may need to handle multiple tasks simultaneously. This includes both small scale and large scale data.
6. Community Support
There is a huge community of developers for C++ who actively involved in promoting this language. Due to this large size, you are most likely to get vast amount of support. For an example, the community actively engages in forums and social media so as to answer all queries. Apart from that they also provide tutorials and other documents that further assist in problem solving.
Disadvantages of C++
1. Learning Curve
Generally, C++ is a language which is hard to learn especially for the beginners. This is due to the fact that there are more constructors involved. i.e. template classes and virtual functions. Even some programmers who have prior knowledge on C programming language find it difficult to grab the concepts.

2. Security
As we all know C++ is an Object Oriented Programming language. Thus, the language is secure on default. However, still there are some security vulnerabilities due to the usage of friend functions, global variables and pointers.
3. Complexity
C++ focuses on multi-paradigm. Therefore, in some cases you cannot use this create apps those are platform dependent. In addition to the learning curve, the complexity further increases with the size of the syntax. When there is more syntax, it creates code complexity. Even a slightest mistake in the syntax can make the output to be invalid. Also, the debugging process takes a lots of time.
4. Lack of Garbage Collector
Other programming languages comes with a feature called Garbage Collector which manually expels unused data, eventually freeing up resources. But this feature is absent in C++. Because there is no dynamic memory allocation here.Â
Even though the memory allocation process is in the hands of the developer, in some instances it can be troublesome because they have to manually allocate memory every time. This process is highly time consuming.
5. Pointer Feature
The pointers in C++ is highly memory intensive as well as a complex concept. Many beginners face difficulties in understanding this concept. Developers who handle pointers must be extra precautious. One single mistake can lead to system crash. Since they also consume memory there is also a tendency for the memory to get corrupt if not handled properly.
6. Thread Support
In the beginning stages, thread was not added in C++. Their design structure did not permit any built in threads. Due to many requirements, later it was added in the newest standards. Unfortunately, it is still less effective when compared with other programming languages.
