  • It lacks generic programming
  • Dependency management is not good in Golang

What is C++?

C++ is one of the general purpose, mid-level, and OOPS-based programming languages created in Bell laboratories. Know that it is the superset of the C language. In other words, it is the extension of the C language. C++ is an OOPS-based language that widely uses objects and functions in programs. With C++, you can create fast and portable programs for large-scale applications. It offers reasonable control over memory and system resources in addition to good flexibility and scalability. Furthermore, C++ is portable, so it can work on any platform seamlessly.

Who uses C++?

C++ can be used to develop software, GUIs, web browsers, databases, and game applications. And you can use the C++ language for desktop applications as well as graphics and image processing.

What are the Key features of C++?

There are plenty of features available for C++. Following are a few key features of C++. Let’s learn them now.

OOPS-based language: As we all know, objects play a key role in OOPS-based languages. This way, C++ allows you to develop applications by managing objects effectively. As C++ is the OOPS-based language, it comes with the properties such as data abstraction, inheritance, encapsulation, and polymorphism. These properties help to increase the efficiency of programs.

Structured Language: Know that C++ has many functions, objects, and classes. Not just that, it supports many data types and operators too. That’s why it is known as the modular language. You can break the large-sized codes into small pieces to efficiently manage the codes. In a way, it helps to create clean codes. So, it allows you to understand the codes quickly and modify them as you wish.

Rich Library: C++ has a Standard Template Library (STL) that helps to write codes quickly. It has many inbuilt functions that header files can easily access. For example, you can get standard libraries for sets, hash tables, maps, and many more.

Memory Management: No wonder C++ allows allocating memory for variables as well as arrays during runtime. It is known as Dynamic Memory Allocation (DMA). Similarly, memory is deallocated if the used variable or array is no longer required. In this regard, you can use the new and delete operators to allocate and deallocate memories. Additionally, C++ supports both stack and heap storage. Here, the stack is used to allocate variables inside the functions. And heap storage is the unused memory that is allocated dynamically.

Pointers: Basically, Pointers store the memory address of variables. With pointers, you can directly interact with memory. Many issues that require memory access can be quickly resolved with pointers.

Multi-threading: C++ allows several parts or threads of programs to run simultaneously. Although C++ doesn't have the inbuilt functionalities for multi-threading, it allows using external libraries for multi-threading.

Integration and Scalability: As C++ is an OOPS-based language, it allows you to create programs that can be extended and maintained quickly. In other words, you can add new features to the programs while developing mobile applications, web browsers, games, and so on.

  • You can make effective memory management with the support of Dynamic Memory Allocation (DMA)
  • C++ offers templates, namespaces, and function overheading, which helps to improvise the C++ programming
  • Since C++ is OOPS-based, it supports abstraction, polymorphism, encapsulation, and inheritance, making the language reliable and reusable.
  • C++ supports generic and imperative programming
  • C++ is the language that is close to machine language
  • The user community is prominent for C++. So, users can take great support from the community.

Drawbacks of C++

Every coin has two faces. On that note, when there are pluses, there will be some minuses, undoubtedly. This way, C++ has a few drawbacks as well. Let’s take a look at them below:

  • It has complexity in dealing with memory
  • C++ uses pointers, which are basically complex. Any misuse of pointers will lead to system crashes and abnormal memory consumption.
  • C++ doesn’t use a garbage collector. Therefore, it is hard to filter unnecessary data.
  • It is not a secure language because of the use of pointers and variables.

Syntax: Golang has a simple syntax. That’s why it is easily readable. On the other hand, syntax in C++ is a bit more complex than in Golang, which decreases the readability.

Generic Types: Golang doesn’t support generic programming. On the contrary, C++ supports generic programming. Mainly, generic programming is supported by class, function, and specialized templates.

Packages: Golang uses packages, whereas C++ uses header files. And C++ has template libraries, whereas Golang doesn't have templates. Also, C++ supports function overheading while Golang doesn’t support the same.

OOPS Concepts: C++ support OOPS concepts such as data abstraction, inheritance, encapsulation, and polymorphism. Not just that, it supports multiple inheritances, either. On the other side, Golang doesn’t support all these things.

Memory Management: Golang offers automatic garbage collection for memory management. On the other hand, C++ doesn’t have a garbage collection option. However, C++ uses a destructor to free up memory but doesn't handle objects safely.

Speed: Golang compiles codes faster than C++ since it has a simple syntax. Not only that, Golang compiles codes faster with the support of Garbage collectors, concurrency options, Goroutines, and multi-core CPUs. Besides, Golang uses Goroutines and channels for compilation, whereas C++ uses threads.

Security: C++ suffers from memory overflow because of buffer vulnerability. As a result, it leads to complications in performance. Golang, on the other hand, has built-in mechanisms that prevent buffer overflows.

Community: No doubt C++ has a large community than Golang simply because C++ is the oldest language out of the two languages.
