3
00:00:11,380 --> 00:00:14,350
Libraries sunt quomodo nos sicut programmers, confer communis et

10
00:00:27,500 --> 00:00:29,820
Nunc, printf non est aliqua magica functio, ut 'been

15
00:00:38,050 --> 00:00:40,920
Quia printf non aedificatur in computer, quod significet quod

Sicut programmers, bibliothecis sunt unum ex maximis

Quando programmers scribere libraries, ipsi typice
