C vs C++

Programming language is claimed to be the mother of most of the foremost known languages. However, the next generations and kid languages took over C terribly simply. Among all the programming languages, C is that the most talked language against and all in this post you will get Differences And Comparison Between C and C++

Let’s take a deeper explore identical and recognize why and the way these languages area unit totally different.

C vs C++: Comparison and variations

Structural or procedural

C is a structural or procedural programing language whereas C++ is a standard or an object-oriented programing language.Let’s look at it this way:

C vs C++

Let’s imagine, you’re build up a house within the archaic times. thus you do not outline the position, size, and configuration of the bricks, windows, and the door. Time flew by and within the epoch, you once more determined to create up a house however now, you outlined everything and in reality, you even had a plan of your house. So, the primary kind of build up a house was procedural. That means, you simply had resources and you utilised them however within the later case, you made the decision everything before hand that means you modularized the development. Now replace the bricks of the house with the bytes and you’d recognize what i used to be talking regarding. Thus, this is often the key distinction between C vs C++.

Use of Virtual functions

No virtual functions are present in C however C++ uses them.

Information hiding support in C++

C doesn’t support info hiding. That means, once an information is outlined in C, it becomes a free entity and might be simply manipulated by outside code. In C++, Encapsulation hides the information to ensure that data structures and operators area unit used as meant.

Encapsulation

Encapsulation makes mapping easier in C++ to map data and functions whereas in C it becomes terribly sophisticated. C++ uses objects for identical purpose.

Programming approach in C and C++

C follows the top-down approach whereas C++ follows the bottom-up approach (remember an object in C++?)

Memory Allocation

C provides malloc() and Calloc() functions for dynamic memory allocation, and free() for memory de-allocation. C++ provides ‘new’ operator for memory allocation and free operator for memory de-allocation.

Function and operator overloading

C doesn’t support function overloading and operator overloading whereas C++ supports function overloading and operator overloading. That means, in C++, one function of identical name is utilized in the various scopes. overloaded functions enable programmers to produce totally different linguistics for a function, depending on the kinds and variety of arguments.

Inheritance

Inheritance isn’t possible in C however it’s possible in C++.

Variable declaration in C and C++

In C programing language, you have to declare a variable at the start whereas in C++ a variable is declared instantly anyplace throughout the program.

C vs C++: Input and Output compared

C uses functions for input/output. for example, scanf and printf. On the opposite hand, C++ uses objects for input-output. for example, cin and cout.

Namespace feature

To avoid collisions, C++ uses NAMESPACE. C has no such feature.

Error Handling in C and C++

C doesn’t give direct support for error handling (also known as exception handling) whereas C++ provides support for exception handling.

C vs C++ speed comparison

Asking the question about the speed of C and C++ is quite biased. C and C++ programming languages are nearly the same when it comes to their performance, given the condition that you are a skilled programmer.

If you code some C statement and them compile them under C++, they’ll run just the same and generate the same machine code. However, C++ is developed as a superset to C and additional code is generated to support the higher level features.

The performance and speed of C and C++ mainly depends upon the decisions a C++ programmer makes. If one person makes a program that relies heavily on the high level tools of C++, the program might appear bloated. However, if one is skilled enough, a programmer can code a C++ program without calling bloated C++ libraries and acheive same level of performance.

Influences of C and C++ on other languages

C has influenced technologies like awk, csh, C++, BitC, Java, JavaScript, C#, D, Objective-C, Concurrent-C Limbo, Perl, and PHP.On the other hand, C++ has influenced C#, D, Aikido, PHP, Java, and ADA 95.
