Sir while loop ky through nikal sakta hy?

[@Vickysagittarius]

sirji, condition main maine $i >= 0 likha tha par ye result pe 0 show kar rahi thi ? aur jab main $i > 0 likh raha tha to ye 120 factorial no of 5 bata rahi thi for loop?
aisa kyun ? $i >= 0 main kya problem thi us main bhi to value 0 se greater hi thi ?

[@pradipmehta10]

kyoki Apne >=0 tak loop chalaye to last loop 0 ka run hua or total number me 0 se multiple hua.
Or kisi bhi number me 0 se multiple hone se whole value 0 ho jati hai. Isliye apke result 0 Aya.
