C vs C++ Comparison: best difference & similarities between C and C++

C vs C++: A Detailed Overview For Every Programming Beginner

C Vs C++: When it comes to programming, there are two languages that we are familiar with from our college days: C and C++. These are the oldest and most widely used languages for a variety of purposes. C and C++ have served as a foundation for many modern languages. The C programming language is used to write various codes on your working windows. The primary goal of this article is to demonstrate the differences between C and C++. Let’s look at both languages before we try to figure out C vs C++.

About C and C++

C was first designed by Dennis Ritchie from 1969 to 1973 to execute on UNIX operating system. It is a general-purpose programming language and it is extremely flexible, popular, and simple. C is the base of all programming languages.

If you are good at C, you can easily understand or grasp the knowledge of other programming languages. After getting inspired by Simula and C, Bjarne Stroustrup developed C++ in 1979.

Founders of both languages operated at Bell Laboratories of AT&T. C++ language was inspired by C. In simple; we can call C++ a subset of C.

Both languages have the same memory model, same compilation, syntax, and code structure. Many programs of C can also run in the C++ compiler.

What You’ve Learned: C is faster and more efficient than C++. C is simpler to program and debug than C++. C is the standard language for source-level programs, such as kernel programming and driver development.

C Vs C++ Salary Comparison

According to Stackoverflow survey 2021, the annual salary of a professional c developer is up to US$53,184. In comparison, a C++ developer is roughly about US$54,049. 

Why Do Developers Need To Design C++?

In comparison, C vs C++ as you know C++ is the subset of C So C++ was designed to deal with the complexity that C couldn’t. For example, because there was no encapsulation, namespaces, or other features in C, you could “run out of names for variables” (not literally).

Also, because C does not allow exceptions, error handling is particularly error-prone because the library user must always check the return values of functions. When a library developer throws an exception, the program flow is guaranteed to be paused.

The function Object() { [native code] } init objects is automatically called by the compiler in C++. Unlike C structs, which need the programmer to populate them (hence another error-prone area).

Finally, OOP offers a slew of other benefits, including object reuse and generic programming-based ideas like templates and generics, allowing you to reuse source code.

C Vs C++: Stackoverflow Survey 2021

Opportunities arise sometimes, and we may choose to change occupations or learn new languages. As a result, many developers wish to shift employment or switch programming languages from C to C++ and C++ to C, according to the stack flow study. You can see an example of this in the images below.

There are 5198 professionals who want to switch their careers in the C programming language
There are 6804 professionals who want to switch their careers in the C++ programming language

The Key Difference Between C vs C++

Data Abstraction

In the C programming language, data abstractions are of a low level. Data abstraction hides all their background detain and displays the only important information. As compared to C, the language C++ provides high-level data abstraction.

Programming Paradigm

The C programming language is a middle-level language that bridges between the high-level language and machine-level language. It was essentially created for writing operating system parts.

For compilation, it follows a top-down approach. C language programs starts with main() function. C language doesn’t support objects and classes as it is a procedural language. It doesn’t support features such as inheritance, polymorphism, and encapsulation.

Polymorphism is defined as the capability of an object to take several forms. Inheritance means the tendency of a child object to inherit the properties of its parents. Encapsulation is used to bind data and functions together.

C++ programming language is recognized as a high-level programing language. It supports both object-oriented programming and procedural language paradigms. C++ supports both objects and classes.

C++ is an advanced object-oriented programming language. It carries features like inheritance, polymorphism, and encapsulation. Here in C++, functions, and data can be encapsulated collectively in the object form. In C++, data are safer; it’s because of encapsulations.


In C++, the Namespace is an additional feature, but this feature is not present in the C language. It prevents name collision. Declarations of the namespace can be made only at the global scope.

Memory Allocation

In both languages, dynamic allocation is different. For memory allocation in C language, we use calloc() and malloc() functions, and for deallocation, we use free(). When we are using C++, for memory allocation and deallocation. We use several sets of operators like Delete and New.

Reference Variables

C++ provides many other things, but C doesn’t like C only supports pointers, but C++ supports both reference variables and pointers. We have only one type of data in C, but in C++, we have user-defined as well as built-in data types.

Inline Functions

The new version of C supports inline functions, but the first version of C doesn’t support them. To speed up the execution it normally works with macros. C++ language supports inline functions as well as macros. 

Exception Handling

The C language doesn’t allow direct handling of exceptions. But in C++ it does with its catch and try blocks. We only have data members in C structures, whereas C++ has both functions and data members

Conclusion ( C Vs C++)

In this blog, we have focussed on C Vs C++ programming languages in terms of several features. As we have seen, several features are restricted to C++. As we have discussed above C++ is a subset of C, and it supports various features of C. 

These programming languages are rare in modern software industries. But these languages are the backbone for many other programming languages like- the Java programing language, Python programming language, etc.

Therefore one should have knowledge of C and C++. Most importantly, it helps new programmers to understand complex computer science theories easily.

FAQ (Frequently Asked Questions)

Is C++ better than C?

C++ has substantially more libraries, and functions than C. C++ is better for working with complicated applications because it has more libraries to draw upon. Understanding C++ is typically a need for numerous programming professions if you think about it.

Should I start with C or C++?

It is not necessary to study C before moving on to C++. They are two distinct languages. It’s a prevalent fallacy that C++ is dependent on C and isn’t a fully defined language in and of itself. C++ and C share a lot of syntax and semantics, but it doesn’t imply you have to master C first.

Where do C and C++ come into play?

C is used in applications that require low-level programming languages. C++ is commonly used to develop graphics-intensive software, game engines, virtual reality applications, and web browsers. Operating systems, embedded devices, OS kernels, drivers, and IoT applications employ C programming.
