1. 1970s – The programming language was C, which was created by Dennis M. Richie. Before he created the C language there was the B language, which was created by Ken Thompson in 1969-70. The computers in that time wrote in assembly code and the user had to write many pages of code to do a task. When the B language was created, it made it possible to do a task in a few lines. Although the B language improved the systems it lacked use of structure and didn’t know data types. So in 1971-73 Dennis Richie wrote the C language in which he kept the B syntax but added data types and other changes that needed to be made. It was built for power and speed and developed for UNIX systems. Its also used for Windows, the MacOS and Linux.
2. 1980s – The programming language was Python, which was created by Guido van Rossum. It’s more of a scripting language and allows users to produce large quantities readable and functional code in a quick amount of time. Python teaches the user how to work with other languages, indentation, and modularity. It supports object – oriented, procedural, and functional program styles. C++ was also created and used many different types of computers. Program A was created by Arthur Whitney in 1988, and it focused on graphics, systems interfaces, utility support, and user community.
3. 1990s – The programming language was Ruby, which was created by computer scientist Yukihiro Matsumoto. It was created to have syntax without having to learn all the commands and specialized vocabulary in order to get going. Its object – oriented and supports procedural, imperative, and functional programming. JavaScript was another program language in the 90s, which was created by Brendan Eich. It has a dynamic language and provides programmers object – oriented program styles, functional, and imperative. It’s very easy to gain knowledge of how to use it and also in your browser. Java, not to be confused with JavaScript...
