Structured programming is a programming paradigm aimed on improving the clarity, quality, and development time of a computer program by making extensive use of subroutines, block structures and for and while loops – in contrast to using simple tests and jumps such as the goto statement which could lead to "spaghetti code" which is both difficult to follow and to maintain.
It emerged in the 1960s, particularly from work by Böhm and Jacopini, and a famous letter, Go To Statement Considered Harmful, from Edsger Dijkstra in 1968—and was bolstered theoretically by the structured program theorem, and practically by the emergence of languages such as ALGOL with suitably rich control structures.

Famous quotes containing the words structured and/or programming:
“The subject of the novel is reality liberated from soul. The reader in complete independence presented with a structured process: let him evaluate it, not the author. The façade of the novel cannot be other than stone or steel, flashing electrically or dark, but silent.”
—Alfred Döblin (1878–1957)
“If there is a price to pay for the privilege of spending the early years of child rearing in the driver’s seat, it is our reluctance, our inability, to tolerate being demoted to the backseat. Spurred by our success in programming our children during the preschool years, we may find it difficult to forgo in later states the level of control that once afforded us so much satisfaction.”
—Melinda M. Marshall (20th century)
