c++ vs golang : Differences Every programmer Should know

Go is a general-purpose, static procedural language developed by Google in 2009. Its primary purpose is to turn down programming efforts. Hence it is easier and faster to write codes, which somehow became a backbone to networking services.

In contrast, C++ is non-procedural Object-oriented, and general programming first appeared in 1985, most developers used C++ in developing games. However, Unlike Golang, programming in C++ is complicated to code and takes more code lines since it is the old-fashioned way of coding.

If you are a C++ developer and looking for what developers say about their speed performance? At that moment, C++ is still leaping forward while compiling lengthy codes. It’s closer to a machine.

And Golang’s version is better overall since it’s a high-level language, so expect a delay in compiling giant codes. C++ is, therefore, used for developing 3D games; it renders well and utilizes CPU thoroughly.

Generally, both languages hold a good reputation worldwide, but C++ has dominated the Desktop app’s industry, as the rule of thumb says. At the same time, GO, or Golang, is still leading forward rapidly as a newborn baby, and as of now, the primary use of this language is handling the backend of large web apps.

There is a brief introduction about them, and later we will explain and compare their abilities in detail.

Go or Golang

It is a general programming language, like Python, having a wide range of applications, which means you’re allowed to do whatever you wish as a programmer: do data scientist projects or web development, you will not see any limitations.

Since it’s also a procedural language, among one of the easiest programming languages out there, it’s said about this easiness. A beginner without any troubles can get into this so far. He is interested in learning. The well-explored official documentation is obviously a plus point.

It first appeared in 2009 at the end of the year and was designed and developed by Rob Pike, Ken Thompson, and Robert Griesemer. Well, its latest updated version is even more robust than compared to what it was before.

And by nature, It is an open-source expect it to be run on all the popular OSs, including Mac OS, Linux, Windows, and, and it was under licensed by BSD.

C++

C++ is also considered as a mid-range general programming language. And it’s among the oldest languages as the first flavor of this language was put forward in 1985. Obviously, At that time, it was not robust enough as today.

It is said about C++. If you master this, there’s no need to look for a further assistant to complete a project. Whether you tackle commuting tasks, desktop applications, or web apps, by the way, the hidden masterpiece of this language is sneaked in the desktop apps.

One of the dominant languages in the industry is popular for its speed and robust development.

The downside of this language for a beginner is, it is hard to walk through as the 3rd generation’s languages. It works on non-procedural concepts. That’s why the lines of codes often get lengthy.

C++ vs Go: Performance

Go is among the super fast languages out there, with features like a garbage collector, static typed, concurrency. With these means, performance-wise, writing programs in Golang will result in a better output. There is not much to mess around if you know what to do.

However, it is a high-level programming language that’s mean a little far from the machine according to the rule of thumb. That’s mean the compilation time of a code is a little higher than C++.

According to expert developers, Golang is memory-safe, so during the compilation process, a lot of CPU power goes into the part and impacts the performance. However, It is equipped with all pieces that can turn down efforts while compiling a code, yet still, the most significant chunk is its, albeit excellent, garbage collector.

C++ speed performance is pretty good during running a code as its exception property lets the code execute quickly. And many factors may act on its performance. For this reason, it’s considered as the flash in the programming world.

Before throwing any collusion, let’s say if only the speed is the thing for you, then C++ can be a better choice, but still remember for a beginner its hard to code and to challenge to understand, for them it cannot perform well.

While Golang follows the modern way of coding, so choosing this so far is the right choice.

Personal opinion: Go is generally not all slower than C++. Except for the moment, your program needs to maximum speed, like doing something related to data analysis where you’ve to mess up with big data. Either way, there is not much difference.

C++ vs Go: Uses and Applications

There are no limits to what you can achieve with these languages. But for the most part, the Golang is useful for web-related tasks as it can stand alone, easy to debug, and at the same time works faster. Some of the best uses of Golang is:

  • Distributed functions or services: APIs.
  • Websites.
  • Web servers.
  • Web apps.

To be honest, here, Golang may have a bright future ahead, and there is no doubt that many giant companies are now coming towards Golang for some reason. However, it’s a new language and does not show up as something crazy in any programming field. We can say it’s still a growing child.

C++ is the oldest programming language, so it makes sense here it is at its full potential. When many people use a language, it grows bigger since the people keep finding a way out if they lack somewhere. And, if I’m not mistaken, C++ has grown almost 37 years. That means a lot.

Talking about its some applications, then the app industry is filled up with this language.

  • Games and Apps.
  • Desktop apps
  • Web browsers.
  • Graphics or image processing.

C++ is closer to a machine, and this closer to a machine makes it super fast for the process that other languages take a longer among of time. For instance, in Game development, such softwares are itself uses C++.

What’s more, people mostly use C++ for building games as well. The reason it increases the performance, its code is a so-called CPU incentive that uses the last drop of the power to run the program.

The Mozilla Firefox is the real-time example of C++, not just this browser. There are plenty of others. What’s interesting here is the logic, as people don’t want their browser to run slow that’s why C++ builds most browsers.

Features comparison

Scroll down a bit to dive into some advanced details, and get to some minor differences somewhere hidden among their use cases.

C++ has some serious support for data hiding that makes it secure to be hacked from the hijackers. And many OO functions like encapsulation, inheritance, or Polymorphism are there in the language to take off.

Go is a modern language, so expect some difference in the way of coding. To explain this better, we’ve shown some features that you better look read them once.

Operators

C++ has a substantial ray of operators for mathematical logic, such as Arithmetic, Rational, Miscellaneous operators.

Luckily the Golang also does support all the operators that you will get in C++. There might not be a big difference. However, Golang made it easier to perform them.

Faster performance

As the rule of thumb says, C++ is pretty much faster as it supports multi-threading, exception handling to run a code throughout exception-free.

Golang has the above abilities. Its concurrency feature makes this even stand out. Seizing it even lightweight and compilation of codes becomes the even faster; As the concurrency can run a part of codes regardless of the following the from AtoZ compilation process.

Miscellaneous functions

C++

  • Namespaces.

Seldom in programming, we have to define two distinct functions with the same name. That’s where the program becomes screwy since there is no way to understand to which to call. Luckily in c++, there is a function called namespace: It is introduced to deal with this difficulty so a language can differentiate similar functions, classes, variables, and so forth even the name is the same.

  • Templates.

Templates are one of the reasons that lead c++ up to some scale. They pre-generic chunk of codes, modules, that have been created by people all over the past since the c++ was first introduced.

It’s also why experts find coding in C++ easier, as they don’t have to write code when they can already search and find it out. The only thing to change there, data types and classes. And you’re good to go.

  •  Implicit

In C++ programming, you can shape data into different shapes, and there are two go-to ways for this purpose.

  • Functions overloading.

This feature lets us allow as many functions with the same name yet different parameters hassle-free. Simply this allowed us to add two, three, four, and many integers numbers in one shot, except defining each time. Otherwise, we either have the limitation to add only two integers to write multiple times the same function, which would lower a code’s readability.

Go or Golang features.

  • Pointers.

In GOLANG, a pointer is an ability to store the memory addresses and points to where the memory is located so we can call back. Termed as a sort of Variable, it declared with *(dereferencing operator).

  • Structures.

Unlike OOP, Golang has structs to introduce a new data type or combine a different form of data into one entity. For instance, let’s say an address has a specific name, street, city, state, postal code, so here we have to combine them into a single structure. Compared to OOP, it is lightweight.

  • Maps.

One of the advantages of Golang is its map feature. Generally, it is a collection of unordered pairs of key-value., it’s used to update or delete specific data.

Some more functions in GO are listed below.

  • Slice.
  • Range.
  • Recursion.
  • Functions.
  •  Interfaces.
  • Type Embedding and Error Handling along with fast compilation process.
