Presentation on Programming Languages.
A programming language allows people to create programs that instruct machines what to do. There are different levels of programming languages from high-level to low-level. High-level languages like C, C++, Java, HTML and XML are more understandable for programmers as they are further abstracted from hardware. Low-level languages work more closely with hardware and do not require compilation. The document then provides examples of programs in C, Java, HTML and CSS to illustrate these points.

- 2. What is aProgramming Languages • A programming language allows people to create programs that tell machines (computers) what to do. A programming language is a tool for developing executable models for a class of problem domains. A programming language is a tool for developing executable models for a class of problem domains.
- 3. Levels of ProgrammingLanguages High-level program class Triangle { ... float surface() return b*h/2; } class Triangle { ... float surface() return b*h/2; } Low-level program LOAD r1,b LOAD r2,h MUL r1,r2 DIV r1,#2 RET LOAD r1,b LOAD r2,h MUL r1,r2 DIV r1,#2 RET
- 4. Types of programme •Imperative Programming (C) • Object-Oriented Programming (C++) • Logic/Declarative Programming (Prolog) • Functional/Applicative Programming (Lisp)

- 7. •C – Developed byBell Laboratories in the early 1970s. – Provides control and efficiency of assembly language while having third generation language features. – Often used for system programs. – UNIX is written in C. High-level Languages

- 10. High-level Languages •C++ – Itis C language with additional features. – Widely used for developing system and application software. – Graphical user interfaces can be developed easily with visual programming tools.
- 11. High-level Languages •JAVA – Anobject-oriented language similar to C++ that eliminates lots of C++’s problematic features – Allows a web page developer to create programs for applications. – Objective of JAVA developers is that it be machine, platform and operating system independent.

- 14. High-level Languages •XML – ExtensibleMarkup Language. – A language for defining other languages.
- 15. Markup Languages •HTML – HyperTextMarkup Language. – Used on the Internet and the World Wide Web (WWW). – Web page developer puts brief codes called tags in the page to indicate how the page should be formatted.

- 19. LOW LEVEL LANGUAGESWORK MORE CLOSELY WITH HARDWARE AND DO NOT REQUIRE A COMPILER TO BE EXECUTED. HIGH LEVEL LANGUAGES ARE MORE UNDERSTANDABLE FOR THE PROGRAMMER IN TERMS OF THE WORDS IN THE CODE. Difference between a high and low-level programming language
- 20. Conclusion • Every oneneed a language to tell an information which is hidden, in such a way programming is a language which is used used for knowing the hidden information of computer related programming
