The major languages in IT (Information Technology) are:

Java - the general-purpose enterprise standard heavily used for server-side web development; used to write Android apps

Python - general-purpose scripting language, popular for numerical computing, financial industry, web development, etc.

PHP - used for server-side web development

C# - general-purpose and largely Windows-centric

C++ - general-purpose and high-performance; used for nearly everything, esp. financial industry, scientific computing, game development

C - used for writing operating systems, device drivers, embedded software, etc., the very foundation of IT

JavaScript - the native language of the web browser; also used server-side in Node.js

Perl - general-purpose scripting language, once very popular, but has since fallen out of favour

Ruby - best known for Rails, a server-side web framework

Matlab and R - languages specializing in statistical analysis

I love PYTHON the most then C++.

@op and any other programmer in the house, pls help me with these questions...

1. Write an assembly code program for the 6502 or Z80 microprocessor to calculate the sum and the difference of the two numbers stored at Cooo16 and Coo16 and store the result at Booo16 (sum) and Boo16 (difference)
2. In a Z80 processor what is the use of HL? If the content of H register is DI16 and the L register is FE16, what would be the result of the instruction ADD A, (HL)?
