What are the pros and cons of C++?

C++ is an object-oriented programming language that was created by Bjarne Stroustrup in 1979. It originated as an extension of C and is commonly employed in low-level programming, such as virtual machines, drivers and operating systems. With a concise set of keywords, C++ enjoys widespread popularity globally. The language incorporates functionalities through the C++ standard library and is highly suitable for diverse platforms. However, it’s important to consider the following advantages and disadvantages of C++.

Advantages of C++

  • Versatility: C++ is a highly versatile programming language with a wide range of applications. Beyond its usage in operating systems, drivers and virtual machines, it is also commonly employed in diverse fields such as game development and security systems.
  • Learning other languages: Despite its complexity, C++ can serve as a beneficial entry point for inexperienced developers. Mastering the logical structure of C++ provides a solid foundation that facilitates the learning of other languages. Once developers internalise the concepts and principles of C++, transitioning to other languages becomes more manageable.
  • Portability: C++ is platform independent, ensuring excellent portability. Code development remains independent of operating systems, allowing for seamless switching between platforms.
  • Memory consumption: C++ exhibits low memory consumption due to its minimal abstraction from the underlying architecture. It also eliminates the need for intermediaries and separate runtime environments. With no garbage collection, memory management is entirely in the hands of the programmer, enabling the release of complete memory blocks when required.
  • Scalability: C++ is highly flexible and scalable, making it effortless to begin with a small project and incrementally expand it over time.
  • Community: C++ boasts a large and supportive community, offering guidance and assistance to newcomers. The language also benefits from extensive documentation resources.

What are the difference between Python and C++?

Now that you have a general idea of the two programming languages, let’s delve into a direct comparison of Python and C++. Below we’ll highlight the main differences between the two programming languages.

Differences in syntax

When it comes to syntax, there are significant differences between Python and C++. Python uses indentations, while C++ relies on semicolons and curly braces for delimitation. Python offers more options for Boolean expressions, while C++ only interprets values that correspond to 0 as false. Additionally, in C++, variables are needed to specify values with a storage location. Python, on the other hand, treats everything as an object.

The following two examples illustrate the syntactic differences of Python and C++. Here’s the syntax of Python:

>>> print("This is the python syntax")

And here’s what C++ syntax looks like:

int main() {
cout << "This is the C++-syntax";
return 0;

Other differences

There are plenty more differences between the two:

  • Learning curve: Python is easier to learn than C++ and has more flexible and concise code. In contrast, C++ demands closer attention, as mistakes are swiftly penalised.
  • Performance: C++ outperforms Python in terms of performance, making it advantageous for large projects. Python’s dynamic typing introduces overhead, resulting in slower execution compared to C++.
  • Garbage Collection: While Python supports garbage collection, C++ does not.
  • Memory Management: As a result, Python has automatic memory management. C++ must be managed manually, but it also offers more setting options.
  • Designation: In Python, data doesn’t need to be labelled by a variable, while C++ requires typing.
  • Use: C++ is commonly employed in large-scale projects and low-level hardware programming. It is also well-suited for building extensive games. On the other hand, Python finds its strength in software development and web applications. It is widely used in machine learning and artificial intelligence.

Python vs C++: Which language is better?

The Python vs C++ duel lacks a clear winner, as the better choice depends on individual preferences and project requirements. Python excels in quick learning and the rapid development of small programs. In contrast, C++ is suitable for large projects and exploring multiple languages, although it requires more time to master. With influential companies like Google favouring Python and Netflix relying on C++, both languages are poised to have significant roles in the future.
