What is Difference Between C and C++ Language

Difference between c and c++

A software programming language is the interaction channel between computer equipment and user, where the customer instructs the machine to execute certain particular kinds through certain commands (published in any programming language).

There are now many common systems programming languages such as assembly, C, C++, Java, Android, Ruby, Python, and so on. there is a lot of difference between c and c++

C is a software programming language of the center stage created by Dennis Ritchie at Bell Lab in 1972, C is regarded as a language of the center stage due to its characteristics. C language includes low-level linguistic characteristics as well as high-level linguistic characteristics.

Bjarne Stroustrup created C++ software programming language in 1980. C++ is a super collection of C programming vocabulary and Simula67 characteristics. C++ brought the class and object notion.

We all are aware of the major programming languages that are used today to make complex programs and C and C++. Though these languages sound similar there are a lot of differences between both of them.

Let’s read about the difference between c and c++ in detail:

C

C++

 

C language was discovered by Dennis Ritchie in the year 1969 at AT&T  labs C++ was discovered by Bjarne Stroustrup in 1979
C language is a subset of C++ C++ is the advanced version of C language and works with the fundamentals of C
This language contains 32 keywords C++ has 52 keywords
C language does not support polymorphism encapsulation and inheritance C++ is an object-oriented language and it supports

polymorphism encapsulation, and inheritance

C language supports procedural programming and has set rules that have to be followed for making the programs This is a highly advanced language and supports both procedural and object-oriented coding.
No information hiding is done in this language Data is hidden by the proper use of structures.
C language is a function-driven language C++ is an object driven language
This language does not support function and operator overloading Function and data overloading is fully supported in the C++ language
The functions we use in C language are not defined inside the structure C++ follows a strict rule for declaration of functions
The header file is used in stdio.h in this language The header file is C++ is defined in iostream.h
No reference variables are supported in the language C++ supports the reference variable
C language does not support inheritance Inheritance is supported in the C++ language
C language focuses on method and process C++ completely focuses on data and then gives importance to method and process
It supports only pointers It supports both pointers and references
C does not allow the programmer to declare any variable C++ supports both Boolean and data types
This language does not support exception handling Exception handling plays an important role in C++
It is a free form source code language The source of for C++ in extracted from C language
C provide malloc() and calloc() functions for dynamic memory allocation. C++ provides a new operator for this purpose.
This language allows Allows Multiple Declaration of global variables. C++ does not allow declaration of variables
The data is unsecured in this language All data entered is completely secured in C++ language
C language follows the top down approach The bottom-up approach is followed in C++ language
The namespace is absent in this language The namespace is present in C++ language
The file extension for C language is .c .CPP is the file extension of C++
The process of mapping is very complicated in this language Mapping can be easily done with the help of objects in C++
C language influences many other languages like: C++, C#, Objective-C, PHP, Perl, BitC, Concurrent C, Java, JavaScript, Perl, csh, awk, D, Limbo C++ influences only C#, PHP, Java, D, Aikido, Ada 95
It is a middle-level language C++ is a high-level language

 

Let’s focus on the Difference Between c and c++ in detail

In C, we use features such as receives), (pushes), (scanf), (printf), (etc. for input or output. These functions expect values of a specific type of data, or in the case of scanf) (or printf), (we need to specify the type of data we want to process the function.

We can use these features in C++ and sometimes. People usually prefer to use the items cin and cout, however. Note that these are class items, and they determine the information sort of the variable when we execute I / O.

C does not promote overloading functions. With the same name, you can’t have various tasks. So suppose you have a function that calculates the square of an integer number and you have to give them separate names to calculate the square of a floating point number.

Give them the same title in C++, and the syntax will determine what feature to use based on the parameter kinds that are transferred to the task.

C does not favor the processing of exceptions. Because of some unexpected turn of occurrences, you should avoid circumstances that contribute to a runtime mistake. In C++, exceptions can be thrown and handled appropriately. This is highly helpful in large-scale initiatives.

In addition to overloading functions, C++ also promotes overloading operators that are not present in C. Would you ever like to combine two strings with the+ driver? Well, hard luck with C, but you can do that with C++.

Classes create everything feasible, of course, and you have to use std:: string instead of standard strings, but then std: string is much better for health.

And the earlier point, std:: string, takes us to this. This is a category for strings (surprise, surprise). Strings in C fashion are much simpler to use and read.

C utilizes malloc) (and free) (for vibrant storage distribution, but C++ has fresh and much superior systems to delete.

Namespaces are becoming common, particularly in the growth of applications, and C++ has approval for namespaces that are missing from C.

An irritating characteristic of C is that at the beginning of their range you need to display all your variables, i.e. straight after the button or function opening button. Defines a variable in C++ anywhere, preferably as close as possible to where it is used.

Would you ever like to produce comparable features that differ only in the kinds of information they handle? You can do this with overloading feature, but this is usually used with the same title but distinct conduct for the feature.

What if you want to do the same thing, but for distinct kinds of information? Writing multiple functions for it doesn’t create much sense. And overloading features do not promote features that differ only by sort of exchange.

This is where the templates are coming in. You can create and use generic functions and classes with any type of data. C++ does not have it, C does not.

In C, various declarations may be available for your worldwide factors. C++ is more stringent, this is not allowed.

After all, C++ is linked to the item. It is impossible to do things like abstraction, inheritance, polymorphism in C. It introduces a whole fresh paradigm to your hands. If you like it, use it. If not, you can do without it

C++ has STL, a very helpful list of templated courses (so you can use them with different kinds of information). Algorithms, information constructions, iterators, etc. are prepared to be produced. Maybe what any programmer in C++ would boast about a C coder.

C refers to the fundamental machine code quite obviously. It is a language that is very context-free. You can look at a for-loop and understand what will come certainly.

The price of this is that the language does not have many abstractions. You have tasks, structures, and unions at the top level. You can use typedef to match certain kinds. Otherwise, it’s a straightforward language, at least conceptually.

For very big software applications, C++ seems to have been usually preferred over C exactly because one can handle abstractions better.

But issues like the absence of a module scheme and a narrow connection with items derived from C, like raw pointers, still plague it.

On the other side, C++ was developed to be more experimental and fluid than C. It began by incorporating courses to C, and much more subsequently.

Conclusion

There are several misconceptions among designers concerning programming languages, C and C++. The most frequent is that C++ is a sophisticated C and one should have a thorough knowledge of the latter language before shifting to the previous language. That’s just a legend, though. The main distinctions between the programming languages, C and C++ are listed below.

C is a middle-level programming language created at Bell Lab in 1972 by Dennis Ritchie C++ software programming language created by Bjarne Stroustrup in 1980 C, a high-level classical programming language that enables you to create C++ firmware and mobile apps, introducing the notion of class and object; encapsulates high and low-level linguistic features.
