Here are a few main features of Golang that will help you know more about its capabilities of Golang.
Easy Development: Golang comes with a simple syntax. It is an easy-to-understand as well as easy-to-use language. That’s why it is known as a programmer-friendly language. With Golang, you can make rapid application development. And it can be done by integrating with debugging tools and deployment environments.
Speed of Compilation: Compilation speed is faster in Golang when compared with other programming languages such as Python, C++, and Java. No wonder you can compile Go codes within a few seconds. This is because of the simple syntax of the language. Once the compilation is over, you will get an executable binary file that won’t have any external dependencies at all. Generally, you can run compiled codes faster than interpreted codes. That’s why Golang achieves high execution speed.
Concurrency: It is a stellar feature of Golang. Golang uses a multi-core CPU setup to execute functions simultaneously. Additionally, Golang uses Goroutines and channels to run functions asynchronously. Know that Goroutines are lightweight tools used to support concurrency. And channels help Goroutines to communicate with each other. Moreover, you can scale applications efficiently using concurrency options.
Standard Library: Golang has a powerful standard library constructed of distributed packages. There are a lot of packages in the library that simplifies the process of writing codes for developers. The packages include HTTP Servers and clients, JSON/XML parsing, security/encryption functionalities, SQL Databases, and more. Mainly, this library eliminates developers’ dependency on third-party packages by providing all the packages required for developing programs.
Garbage Collection: It is one of the prime features of Golang. The garbage collection mechanism is used for making effective memory management. For this, Golang uses a mark and sweep collector. In a way, garbage collection eases the task of concurrent programming. In short, Golang helps to manage complex programs easily.
Golang has many advantages over other programming languages. Let’s take a look at them below:
Drawbacks of Golang:
No wonder Golang has a few drawbacks as well. Here is the list of drawbacks. Let’s have a look at them.
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.
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.
C++ comes with many advantages. Let’s see them below.
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:

Many similarities exist between Golang and C++. Below is the list of the similarities. Let’s go through them now.
There are many differences exist between Golang and C++. Following are the listicles of the differences. Let’s see what they are:
Language: Golang is the procedural language, whereas C++ is the OOPS-based language. That’s why, Golang has no constructors, classes, and deconstructors, but C++ has all these things. Codes in C++ programs are usually lengthy, whereas it will be a few in Golang.
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.
The below comparison table will help you to get a quick overview of the differences between the two languages. Let’s have a look at the table.
