Difference Between C and C++

C and C++ are both computer languages used to create apps, games, database systems, operating systems, and other things. While C and C++ may sound similar, their features and applications are not.

C is a programming language that does not encourage objects or classes. And C++ is an upgraded version of C programming that supports object-oriented programming.

C vs C++

The main difference between C and C++ is that C, developed by Dennis Ritchie is a function-driven language and is divided into modules and procedures whereas C++, developed by Bjarne Stroustrup, is an object-driven language and is divided into classes and functions. C is not compatible with other languages whereas C++ is.

C vs C

C is an essential programming language that may be used to develop everything from operating systems (such as Windows) to complicated applications such as the Oracle database, Git, Python interpreter, and many more.

In 1972, Dennis Ritchie designed C, an intermediate procedural language, at Bell Lab.

C++ is a programming language developed at Bell Labs by Bjarne Stroustrup in the early 1980s.

It is very similar to C, and it is so compatible with C that without changing a single bit of code, you can create 99 percent of C applications. C++ is a safer and more well-structured programming language.

What is C?

Dennis Ritchie, a computer scientist at Bell Laboratories, created it in 1972.

C is renowned as God’s programming language since it serves as the foundation for numerous modern-day languages such as Python, Java, C++, and many more.

The C programming language was built with the intent of developing system software in consideration. It is a great programming language for developing firmware systems.

C programming is a procedural or structural programming language. This machine-independent language was created to provide tools that could operate on the Unix platform.

Since it contains both high- and low-level properties, C is categorized as an intermediate computer language.

It is a foundational language for beginners or new programmers since it serves as the framework for other programming languages.

Because it serves as the foundation for other programming languages, C is frequently utilized in a variety of applications. It is a basic language that allows for speedier execution.

In today’s industry, there are several opportunities for a ‘C’ developer.

It divides a program into modules. Each module may be written independently, and when combined, they constitute a single ‘C’ program. This framework facilitates process testing, maintenance, and troubleshooting.

What is C++?

In a broad sense, C++ is an object-oriented language of programming that is used to develop strong applications.

With its promise for more advanced virtual datasets and objects, this new method of programming language changed the coding world.

It was originally known as C with classes (first object-oriented language).

It is considered a language of programming that incorporates the features of the C and Simula67 languages (a first object Oriented language). Classes and objects for consumer-defined data types were established in C++.

Today, C++ is more than simply an extension to the C programming language; It is among the most widely used and sought-after computer languages, thanks to its contemporary revisions and high-end performance.

Top-tier firms such as Amazon, Google, Facebook, and many more use C++ as their programming languages. It encompasses both high- and low-level linguistic elements.

As a result, it is classified as an intermediate-level language.

GUIs, browsers, games, operating systems, libraries, database engines, enterprise software, embedded systems, cloud/distributed systems, and so on are examples of C++ applications.

Although it is well-known for its flexibility, it does have certain drawbacks. C++ shares some of the infamously difficult-to-understand principles that defined C.

Pointers are a difficult concept to understand, and their exploitation can result in system failures and anomalous memory usage. Another limitation of C++ is the prevalence of security concerns linked to the provision of references, global variables, and buddy functions. 

Main Differences Between C and C++

  1. Dennis Ritchie invented C, while Bjarne Stroustrup invented C++.
  2. C is a form of procedural programming, whereas C++ is an object-oriented language of programming.
  3. C has 32 keywords while C++ has 52 keywords.
  4. C does not allow for inheritance. C++, on the other hand, does enable inheritance. 
  5. C is divided into modules and procedures and C++ is divided into classes and functions.
  6. Polymorphism is not possible in C. On the other hand, C++ does use it.
  7. C has established data types, but C++ includes both installed and consumer-defined data types.
  8. C is a function-driven language and C++ is an object-driven language.
  9. C is not compatible with any other language. Meanwhile, C++ is extensible with a wide range of many other computer languages.
  10. In C, data is not secured whereas in C++ data is secured.
Difference Between C and C


After looking at the characteristics, disadvantages, and benefits of both C and C++, one can see that they are both ideal for different types of projects.

C, without a doubt, is a basic and efficient programming language that serves as the foundation for several prominent languages, including C++.

C++, on the other hand, is an extension of this language that, in addition to all of the advantages of C, includes principles from object-oriented programming such as encapsulation, abstraction, inheritance, and so on.
