Böhm, Jacopini, and Dijkstra

The theory of programming languages is vast, and one of the important concepts is structured programming.

We will learn to program using fundamental structures.

Remarkable is the study published in 1966 by Corrado Böhm and Giuseppe Jacopini ("The Structured Programming Theorem"), followed by the work of the Dutch scientist Edsger W. Dijkstra, who rooted the notion of structured programming in 1968. A period of scientific glory, if you consider that Neil Armstrong stepped on the Moon the following year...

The principle is this:
Any algorithm that has inputs and outputs, meaning a starting point and an ending point, can be represented through a combination of three fundamental control structures called:
sequence (linear structure)
decision (alternative structure)
loop (repetitive structure)
Structured programming allows programs to be written in natural language (called pseudocode), independent of the practical language.

Programs are based on calculation algorithms, which can be translated into flowcharts, like the one below:

We will also use flowcharts in this course. They are super cool, synthesizing the algorithm and helping you better understand how the program works!
Remember these important details.
