El Llenguatge de Programaci\u00f3 Pascal<\/strong><\/h1>\n
\"Niklaus

Niklaus Wirth, dissenyador de Pascal com a llenguatge de programaci\u00f3, i tamb\u00e9 modula-2 i Ober\u00f3n. \u00c9s a m\u00e9s un dels pioners en Enginyeria de Software.<\/p><\/div>\n

Presentat el 1970<\/strong> per Niklaus Wirth<\/strong>, Pascal<\/strong> va ser dissenyat per a for\u00e7ar la implementaci\u00f3 de programes ben estructurats, clars i reduir el nombre d\u2019errors durant el desenvolupament. Aquestes caracter\u00edstiques el convertiren prompte en la refer\u00e8ncia per a la doc\u00e8ncia de programaci\u00f3 a la universitat.<\/p>\n

Pascal<\/strong> \u00e9s un llenguatge fortament tipat, amb codi dividit en fragments amb sem\u00e0ntica pr\u00f2pia (funcions o procediments) i amb variables que han de ser declarades com a pas previ a l\u2019\u00fas, que impedeix la interpretaci\u00f3 o conversi\u00f3 de valors, com per exemple fa C<\/a>.<\/p>\n

\u00a0<\/p>\n

\"Pascal<\/a>

Pascal Book, 1970 Edition<\/p><\/div>\n

Aquestes caracter\u00edstiques avui comunes foren pioneres en el moment de presentaci\u00f3 de Pascal, i feren que un llenguatge pensat exclusivament com a recurs did\u00e0ctic penetrara en el mercat com a llenguatge de prop\u00f2sit general i utilitzat en multitud d\u2019aplicacions en distints escenaris, des de l\u2019\u00e0mbit de la investigaci\u00f3 fins al desenvolupament de jocs. Pascal va ser el llenguatge utilitzat per a l\u2019Apple Lisa i els primers Macintosh.<\/p>\n

Les primeres versions de Pascal tradu\u00efen el codi font a codi per a una m\u00e0quina virtual (m\u00e0quina-P), fet que permetia executar programari en distintes arquitectures nom\u00e9s reimplementant la m\u00e0quina-P. Aquesta idea la revisen anys despr\u00e9s altres llenguatges.<\/p>\n

L\u2019evoluci\u00f3 de Pascal el port\u00e0 des de la possibilitat de crear finestres en un entorn no gr\u00e0fic (MS-DOS) a la programaci\u00f3 orientada a objectes amb Delphi, pensat per al desenvolupament d\u2019aplicacions visuals en entorn Windows. Avui (2021) Free Pascal \u00e9s el sistema de refer\u00e8ncia per a programar en Pascal; l\u2019entorn Lazarus, un clon del Delphi, t\u00e9 versions tant per a Windows com per a OS X i Linux.<\/p>\n
