factorial(n) ni hisoblash uchun rekursiv algoritmni soddagina qilib, quyidagicha yozishimiz mumkin:
if(n == 0) return 1;
elsereturnn*factoriaL(n-1);
Rekursiv chaqirish bir qancha rekursiv chaqirishlarni sodir etishi mumkin, chunki, funksiya quyi pog`onali masalani bir nechta quyi pog`onali masalalarni hisoblash orqali hisoblaydi. Rekursiv funksiya ishini to`xtatishi uchun masala so`nggi hisoblash holatiga qadar qayta ko`rib chiqilaverishi kerak. So`nggi hisoblash holatida funksiya uning chaqiruvchisiga qiymat qaytaradi, qiymatni qabul qilib olgan funksiya esa, o`zining chaqiruvchisiga qiymat yuboradi. Bu jarayon original (asosiy) masalaga qiymat yuborilguncha davom etadi. Va nihoyat, original masala factorial(n-1) ning yuborgan qiymatiga n ni ko`paytirishi va natijani qaytarishi mumkin.
