The document discusses the history and importance of programming languages. It notes that programming has its origins in the 18th century with Charles Babbage's work. It states that programming languages are essential to computer science as programming is an explanatory activity that requires language to communicate ideas. Different types of languages are used for programming, descriptions, designs, architectures, and specifications.

1. Programming Language

2. Computer Science Is About
Programming
● How to build systems.
○ Better, faster, cheaper.
○ Reliable, maintainable, extensible.
● Evaluating and comparing systems.
○ Performance, behavior, security.
○ Compliance, usability.
● What can and can’t be done.
○ Algorithms and complexity.

3. Programming Is Linguistic
● Programming is an explanatory
activity.
○ To yourself, now and in the future.
○ To whoever has to read your code.
○ To the compiler, which has to make it run.
● Explanations require language.
○ To state clearly what is going on.
○ To communicate ideas over space and
time.

4. Programming Languages Are
Essential
● Therefore languages are of the
essence in computer science.
○ Programming languages, in the familiar
sense.
○ Description languages, design patterns,
architecture languages, specification
languages.

5. Histroy of Programming ?
● People believe it is an invention of late
20th century !
● It evolve in 18th century, when Charles
Babbage was studying at Cambridge
University in Britian(in 1822)
● He identified critical errors in the
calculating devices of the time.
(like astronomical tables, tidal charts, & navigational charts)

6. What is Programming Language
?
● “Programming is the ability to talk to the computer in a
language it can understand and using grammar and
syntax that it can follow to get it to perform useful tasks
for you”

7. Programs needed to create
Programs
● There are two kinds of program that
help you write code and make
programs:
○ A developed environment (IDE)
○ A compiler

8. IDE
● Stands for Integrated Development
Environment
● also known as integrated design
environment or integrated debugging
environment
● It is a software applications that
provides an environment to
computer programmer for software
develop

9. Advantages of IDE
1. Less time and effort
2. Enforce project or company standards
3. Project management

10. Disadvantages of Using an
IDE
1. Learning curve
2. A sophisticated IDE may not be a good tool for beginning
programmers
3. Will not fix bad code, practices, or design
