Para sa mga walang magamit na computer ngayong quarantine at sa mga madaming iniisip at hindi maisingit dahil sa sitwasyon. I'm with you guys <3 Pero hindi ko muna binuo. Kailangan talaga matuto tayo eh. Kasi wala ring silbi pagaaral kung hindi mo pinagaaralan. Nandito na lahat guys. May comments naman sa loob ng code. Analyze niyo na lang at gawa kayo ng sarili niyong version or kopya ng mga parte depende sa pangangailangan. Kunin niyo lang yung pinaka idea. Sure akong malalaman agad ni maam pag kinopya niyo lahat. Nonetheless God bless guys keep safe!
Final output nung sakin. Download niyo na lang kung gusto niyo i-analyze.
EXE Application. Pwede i-run: https://git.io/JJnjx
PDF Documentation: https://git.io/JJnjN
Final code ko: https://git.io/JJnj1
Iba yung code nung sakin kasi may sinubukan akong ibang approach. Wag niyo kopyahan guys.
Alam ni ma'am yung style ko please wag niyo na subukan para hindi tayo mapahamak HAHAHAHA.
UPDATE: Marami akong binagong line sa code. Kung nakopya niyo na nung una, kopyahin niyo ulit. Important yung mga pinalitan kong line. Salamat!
