2.15. Pul birliklarini hisoblash
Key Point. Bu qismda pul birligining katta hajmini kichik birliklarda hisoblash masalasini dasturlash qaraladi.
Faraz qilaylik biz katta hajmda berilgan pul birligini kichik hajmda gi birlikda hisoblashni amalga oshirmoqchimiz. Foydalanuvchi dasturga double turidagi, katta hajmli pul birligi qiymatini birlikning butun qiymati va tangalarda kiritadi. Dasturning bajarilishi natijasida chiqarilgan ma’lumot uning tangalardagi minimum hiajmdagi ekvivalent qiymatni chiqaradi.
Bu yerda dasturni ishlab chiqish bosqichlari keltirilgan:

1. 
   Foydalanuvchini 11.56 kabi o’nli son ko’rinishidagi qiymat kiritishga undash;
   
2. 
   Pul birligi qiymati (11.56) ni tangalarga o’tkazish (1156);
   
3. 
   So’mlar sonini aniqlash uchun tangalar 100 ga bo’linadi va qoldiqlarni tanga sifatida olinadi;
   
4. 
   Chorak qiymatni olish uchun qoldiq tangalarni 25 ga bo’lib, chiqqan qoldiq olinadi;
   
5. 
   Qoldiq tangalar 10 ga bo’linib, uning qoldig’idan kichik tanga qiymati olinadi;
   
6. 
   Qoldiq tangalar 5 ga bo’linib, uning qoldig’idan eng kichik tanga qiymati olinadi;
   
7. 
   Qoldiq tangalar – kichik qoldiq tangalardir;
   
8. 
   Natijani chiqarish.
