C and C++

C and C++ differences :

C is a high-level programming language that was developed in the mid-1970s. ... C++, pronounced "C plus plus," is a programming language that was built off the C language. The syntax of C++ is nearly identical to C, but it has object-oriented features, which allow the programmer to create objects within the code.


The difference between C and C++ is:

Python

What is Python?

Python is a high-level programming language designed to be easy to read and simple to implement. It is open source, which means it is free to use, even for commercial applications. Python can run on Mac, Windows, and Unix systems and has also been ported to Java and (.NET) virtual machines.

Here are just some of the advantages of Python:

• Easy to learn and excellent for beginners, yet superb for experts
• Highly scalable, suitable for large projects or small one-off programs known as scripts
• Portable, cross-platform
• Embeddable (making ArcGIS scriptable)
• Stable and mature
• A large user community

Java and Java script

Java:  

Java is a computer programming language. It enables programmers to write computer instructions using English based commands, instead of having to write in numeric codes. It’s known as a “high-level” language because it can be read and written easily by humans. Like English, Java has a set of rules that determine how the instructions are written. These rules are known as its “syntax”. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute.

There are several reasons why you should consider learning  java, and they are:1) Java is popular.Java continues to be one of the most popular programming languages in the world. There's an infinite number of ways to use Java2) Java programmers are employable.Java programming skills remain in high demand with employers. It's a widely used language with a large installed base.3)  Java is used in real world applications.                                             Java is used in many of the world's most prominent web sites, including eBay.com,Linkedin.com, Amazon.com, and Facebook.com.

4) Java has the world's leading developer certifications.Many technical training institutions, colleges and universities offer courses in java programming. You can also invest in Java training from Oracle University. Validate your skills to employers by earning a Java certification, one of the most well-respected developer certifications in the world.

          Javascript:

JavaScript is a programming language that is run by most modern browsers. It supports object-oriented programming and procedural programming. It can be used to control web pages on the client side of the browser, server-side programs, and even mobile applications. This language is used commonly in combination with HTML, CSS, and AJAX.

      Difference between Java and Javascript is in the table below:

What is programming language

 A programming language is a computer language engineered to create a standard form of commands. These commands can be interpreted into a code understood by a machine. Programs are created through programming languages to control the behavior and output of a machine through accurate algorithms, similar to the human communication process.

A programming language is also known as a programming system, computer language or computer system.

 For any beginners who have just started to learn how to code or for anyone who would like to start it, it can be a little bit daunting! There are many different programming languages to choose from and sometimes it can be difficult to choose which one to start with or which one would suit you.
