C Language

C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.

In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard.

The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons −

• Easy to learn
• Structured language
• It produces efficient programs
• It can handle low-level activities
• It can be compiled on a variety of computer platforms

Why use C

• C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language.

  C++ language

C++ is a computer programming language that contains the feature of C programming language as well as Simula67 (first object Oriented language). C++ introduced the concept of Class and Objects.

It encapsulates high and low-level language features. So, it is seen as an intermediate level language. Earlier it was called “C with classes” as it had all the properties of the C language.

 Java language

Java is programming language developed by Sun Microsystems. A small software development team developed this language. They were known as the Green Team, who initiated Java language in the year 1991.

History of C++

C++ language was developed by Bjarne Stroustrup at AT & T Bell Laboratories. Stroustrup was a strong supporter of C and an admirer of Simula67. He wanted to combine the best of both the languages. He was aiming to create a language which supports object-oriented programming features and still retains the power of C. This resulted in C++.

History of Java

The Java language was initially called OAK. Originally, it was developed for handling devices and set-top boxes. Oak was a massive failure. Thus, in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web development business.

Later, in 2009, Oracle Corporation acquired Sun Microsystems and took ownership of two key Sun software assets: Java and Solaris.

 

Key Difference between C++  vs. Java

Some of the points are explained below that shows the Differences Between C++ and Java

• C++ uses the only compiler whereas, in Java, compiler and interpreter both are used.
• C++ supports operator overloading and multiple inheritances but Java does not.
• .C++ uses the concept of header files to include different libraries in the program. Java uses import functionality to include different classes and its methods in the program.
• C++ provides support for default arguments whereas Java does not.
• C++ has the concept of scope resolution operator( :: ) which is used to define a method external to the class, whereas Java uses single dot( . ) which can be used to qualify classes with the namespace they came from.
• Java does not use a go-to statement like C++.
• Java supports method overloading whereas C++ supports method overloading as well as operator overloading.
• Java has the concept of pass-by-value.
• Java does not have the implementation of unsigned integers whereas C++ has.
• C++ has no support for Threads like Java, C++ achieve the functionality of thread using external libraries.
