There are 3 languages that are ruling the world of programming. They are C, C++, and Java. These languages are building blocks of many programming languages. In this blog we will discuss them in brief and will see how they differ from one another.
Introduction to C
C, developed in 1972 especially for unix operating system is a high level language. It was developed after B language which came in 1970. It is widely used language now-a-days as it is easy to learn and also can be compiled on wide range of computers. Not only this, efficient and versatile programs are build using this.
Introduction to C++
Super set of C is C++. It is also a general purpose language. It is complied but life of serious programmers. It is flexible than C, this makes it more efficient. The X-factor in C++ is the concept of class. These are the user defined type. Many C++ institutes offer advance courses in it as it is the need of very IT industry.
Introduction to Java
Developed in 1991 but was available to public in 1995. It is owned by Oracle Corporation. It is object based language. Its syntax is similar to C and C++. The latest working version of Java is 13 which came in 2019 only. There are now so many core java training institute in Delhi which can help you be pro in the field.
Now, Lets see,
How C, C++ and Java Differ from Eachother :
1. Different Paradigms
The main difference between the 3 of these lies with the different programming paradigms that they use. C is a procedural language whereas C++ and Java are Object Oriented.
2. Range of Keywords
They have different range of keywords. C has 32, C++ has 63 whereas Java has 50 defined keywords.
3. Supporting Header Files
C and C++ both support header files whereas Java does not support header files, it uses packages, where packages are imported into java platform.
4. Criteria of Inheritance
Inheritance is considered as an important aspect of programming language. There are two types of inheritance, single as well as multiple. Single inheritance is supported by C as well as Java. But C also supports Multiple Inheritance unlike Java. Whereas no such criterion is supported by C++.
5. Different Kinds of Storage Allocators
All three uses different types of storage allocators. C uses malloc and calloc function library for dynamic allocation. C++ uses new and delete function Whereas Java uses garbage collector for the same purpose.
6. Constructor and Destructor Class
Constructor is a class which initialises each and every project whereas Destructor takes part on destroying that class. Neither C nor Java supports this. whereas it is supported by C++.
7. Use of Multithread and Interfaces
When two or more parts of a programs are executed consequently at that time CPU is utilized at its maximum this is called multithreading and each part of such programs is known as thread. This feature is only supported by java and not the other two.
8. Use of different types of approach
C uses a Top-Down approach whereas Java, as well as C++, use Bottom-Up approach. These approaches are used to gather the knowledge and processing of a program.
9. Language Translators Used
C and C++ use compiler only as a language translator whereas Java needs both compliers as well as an interpreter for interpretation of language.
10. Code Execution Machine
Execution of code is done directly in C as well as C++ unlike Java where code is not executed directly and requires proper JVM i.e. Java Virtual Machine to execute the code.
Conclusion
I hope now you must have understood the main differences that distinguish the three most wanted programming languages in the field of IT industry. You can start of your journey with the basic i.e. C by joining C courses in Rohini and then after learning this can go for C++ as well Java. ADMEC Multimedia Institute is considered as the best C++ institute as well as core java institute in Delhi.
