How many PL are the in the world?
At least 256
https://www.quora.com/How-many-programming-languages-are-there-in-the-world
list on wiki
https://en.wikipedia.org/wiki/List_of_programming_languages
But Hey
There are old languages
Why do we care?
The First Three PL
- 1
- 2
- 3
The First Three PL
- FORTRAN(1954)

The First Three PL
- FORTRAN(1954)
- COBOL(1959)

The First Three PL
- FORTRAN(1954)
- COBOL(1959)
- LISP(1958)
They still exist
More than you think
- over 70% HPC still run FORTRAN
you might get higher pay with COBOL- LISP is everywhere
We also have lots of new languages
Golang
Julialang
Rust
Clojure
......

Hey Dude,
What the FuXX
What are these for?
Algorithm?
What is algorithm?
How can we prove they exist?
Definition of algorithm
a procedure for solving a mathematical problem in a finite number of steps that frequently involves repetition of an operation
Imperative v.s. Functional
They are just different ways of thinking
Imperative lang
C, C++, Python, java, ruby, C#, ...
Functional lang
LISP, Haskell, F#, ...
What are PLs?
Ways to communicate with computers
What are computers?
Machines that help us do some task
PL help us to express our logic
mid-QA
