Riga 38:
Le SLOC come metrica e' nata con i tradizionali linguaggi tradizionali line-oriented( [[FORTRAN]], [[assembly|assembler]], [[C (linguaggio) | C]]). In questi casi la misura delle linee di codice dava effettviamente una fotografia veritiera delle complessita' del software. Oggi con i paradigmi ad oggetti non e' piu' cosi' vero. E' chiaro pero' che la SLOC risulta la metrica di complessita' del codice piu' facile da misurare e da implementare. Queste caratteristiche fanno si che sia ancora molto usata.
==Esempi==
Ecco le SLOC dei sistemi operativi Microsoft:
