سلام خدمت تمامي دوستان سرمايه دار

من دنبال يه برنامه هستم كه هنوز نتونستم پيداش كنم

شرح برنامه مورد نظر:
من يه برناممه اي ميخوام كه تاريخ ميلادي رو به تاريخ شمسي برگردونه و برعكسش

البته تو سايت http://www.persianforum.net فكر كنم يه همچين چيزي گذاشته بود ولي من موفق نشدم تو اين سايت ثبت نام كنم.(انشالله كه شما بتونين )

تو سايتاي خارجكي هم گذاشته بودن ولي به جاي تاريخ شمسي تاريخ قمري رو داشت.

خلاصه هركس آدرس همچين برنامه اي رو داره بده. من خودم دسشتو مي بوسم.

سلام آقا مهدی .
این یه کلاس #C که خودم نوشتم البته الگوریتمش ماله یکی دیگست ببین بدردت میخوره خواستی با C هم فکر کنم داشته باشمش.
