Differences between Python and C++

C is a mid-level, case-sensitive, object-oriented language. Bjarne Stroustrup created C at Bell Labs. C is a platform-independent programming language that runs on Windows, Mac OS, and UNIX. C is closer to the hardware and allows low-level programming. This gives you control over memory, improved performance, and reliable software.

Python is a general-purpose high-level programming language. Python is used for web development, machine learning, and other cutting-edge software. Python is suitable for new and experienced C and Java programmers. Guido Van Rossam created Python in 1989 at the Netherlands National Institute. Python was released in 1991. Beginners should learn Python.

Read this article to get an overview of C and Java and the differences between these two programming languages.

What is C?

C is a statically typed, compiled, multi-paradigm, general-purpose programming language with a steep learning curve. It is widely used by video games, desktop applications, and embedded systems. C is so compatible that almost any C source code can be built without any changes. Object-oriented programming makes C a more structured and safer language than C.

Features of C

Let’s look at some of the features of C and the reasons for its popularity.

##Intermediate Level Language - It is an intermediate language as it can be used both for system development and for mass consumer applications like media players, Photoshop , game engine, etc.
Execution Speed - C code runs fast. Because it is a widely compiled and used process. Garbage collection, dynamic typing, and other modern features hinder program execution.
Object-Oriented Language - Object-oriented programming is flexible and easy to manage. Large applications are possible. Growing code makes procedural code more difficult to handle. The main advantage of C over C.
Extensive library support - C has a huge library. Support third-party libraries to achieve rapid development.

C Example

Let us understand the syntax of C through the following example.

#include
using namespace std;
int main() {
   int a, b;
   cout << "Enter The value for variable a \n";
   cin >> a;
   cout << "Enter The value for variable b";
   cin >> b;
   cout << "The value of a is "<< a << "and" << b;
   return 0;
}

In our example, we are taking input from the user via keyboard for two variables "a" and "b" and displaying the data on the console.

< /p>Output

When executed, it will produce the following

Output -

Enter The value for variable a
10
Enter The value for variable b
20
The value of a is 10 and 20

What is Python ?

Python is one of the most widely used programming languages. It is an interpreted programming language that operates at a high level. Python has a much lower learning curve compared to other languages and is also very simple to use.

Python is the programming language of choice for professionals in fields such as artificial intelligence, machine learning (ML), data science, Internet of Things (IoT), etc. as it excels in both scripted applications and standalone programs.

Apart from this, Python is also the preferred language as it is easy to learn. Reduced maintenance costs due to its excellent syntax and readability. The modularity of the program and the reusability of the code both contribute to its support for various packages and modules.

Using Python, we can perform-

Web Development
Data Analysis and Machine Learning
Automation and Scripting
Software Testing and more

Features of Python

Listed here It has some important features of Python −

Easy to learn − Python has a simple structure, few keywords, and clear syntax. This makes it easy for students to learn quickly. Code written in Python is easier to read and understand.
Easy to Maintain - Python’s source code is very easy to follow. < /p>
Large Standard Library - Most Python libraries are easily portable and run on UNIX, Windows, Mac.
Portable - Python can run on a variety of hardware platforms, and all hardware platforms have the same interface.

Python Example

Look at the simple Python program below -

a = int(input("Enter value for a"))
b = int(input("Enter value for b"))

print("The number you have entered for a is ", a)
print("The number you have entered for b is ", b)

In our example, we have taken two variables "a" and "b" and assign some values to these variables. Note that in Python we do not need to explicitly declare the data type of a variable as PVM will assign the data type based on user input.

input( ) function is used to get input from the user through the keyboard.
In Python, the return type of input() is only a string, so we must explicitly convert it to the data type we need. In our example, we explicitly cast to the
int type via the int( ) function.
print( ) is used to display output.

Output

When executed, this Python code will produce the following output -

Enter value for a 10
Enter value for b 20

The number you have entered for a is 10
The number you have entered for b is 20

Difference between C and Python

The following table highlights the main differences between C and Python -

Comparatively basic	C	Python
Simplicity	C is not as easy to use as other languages because it has more syntax rules and programming conventions.	Python is an easy language to learn. Its syntax is simple and easy to learn. Additionally, its features are easy to use so you can write short and easy-to-understand code.
Speed	C is faster than Python because it is statically typed, which makes it easier to compile the code quickly .	Python is slower than C because it is dynamically typed and uses an interpreter, which slows down the compilation process.
Efficiency	The best compile-time optimizer, C-like syntax, powerful OOP functions and operations Character overloading.	Formatting options not commonly found in other languages, a script-like language, OOP capabilities, and the ability to reuse code through libraries.
Garbage Collection	Garbage collection C is not supported, but can be added.	Python has garbage collection capabilities
Rapid prototyping	Rapid prototyping is possible, but setting up the project can be difficult; Live Translation via IRC Bot	Rapid prototyping is possible, project setup is simple, and there is a live interpreter.

Conclusion

Python’s simple syntax makes it easy to read and code. Python is a good choice for building website backends, while C is less popular for building any kind of backend. website.

Python is also an excellent language for analyzing data and teaching computers how to learn. Although it is possible to use C for machine learning, it is not a good choice. Python is easier to use and has a great support system when it comes to artificial intelligence and machine learning frameworks.
