MICROPROCESSOR SIMULATOR

(NALAIK PANDOO UTHA LO YAHA SE PROJECT OR PRINT KARWA KER SIR KO DO, OR MERI JAN CHORO, MEI KOI ROBOT TO NHI HU, MUJHE BHI DIN MEI 24 HRS HI MILTAY HAIN.
CLASS FELLOWS CHOR KER AB JUNIORS B PECHAY PER GAYE HAIN, YAR YE ASSIGNMENT MILI HAI, YAR IS SUBJECT KA KOI PROJECT BANANA HAI.YAR YE ABEEL NISAR JO HAI NA BARA HI ZAHEEN BACHA HAI, IS KO SUB KUCH ATA HAI.
ABEEL NISAR KOI UPPER SE SEIKH KER AYA THA,YA AASMAN SE SUB KUCH UTARTA HAI MERE DAMAGH MEI, WATT LAGAO SAREY MILL KER MERI, JIS DIN SHIRAFAT KA JANAZA NIKAL GAYA NA TO MEI TUM SUB KI WATT LAGA DU GA.I REALLY MEAN IT.
ISS LIYE THORA HOLA HATH RAKHO OR KISI DOSRAY KA BHI KHAYAL KAR LIYA KARO.TUMHARA MATLAB PURA HO GA TO TUM LOGO NE SALAM KA JAWAB BHI NHI DENA.)
