- Algorithms + Data Structures = Programs
-
is a 1976 book written by
Niklaus Wirth
(designer of the famous Pascal programming language)
covering some of the fundamental topics of computer programming,
particularly that
algorithms and data structures
are inherently related.

- Algorithms + Data Structures = Programs
- Facts:
- A computer program is used to
solve (a specific) problem
- In order to solve a problem,
we must have
information
about the problem
- Information is organized in data structures to facilitate usage (= information retrieval, update, and so on)
- A computer program is used to
solve (a specific) problem
- Hence:
- An (non-trivial) algorithm
will often use (one or more)
data structures
to store relavant information
(Information is essential to solve any problem.
- Case in point:
- CEO's of major companies uses sale information to make decisions on the most profitable course
Humans (and computers) cannot solve a problem without adequate information:
- An (non-trivial) algorithm
will often use (one or more)
data structures
to store relavant information
