arun kumar  (8 years ago)

loop enters for 5 time and each time d value gets changed

d=0 p=2
d=2 p=4
d=2 p=8
d=10 p=16
finally d=10+(2*8)===>26 is the output .. and p=32 then exit the loop

n=11010 then rem=0 , d=0+0*1=0 , p=1*2 =2, num=11010/10=1101 then prints d as 0
n=1101 then rem=1 , d=0+1*2=2, p=2*2=4 ,num=1101/10=110 then prints d as 2
n=110 then rem=0 , d=2+0*4=2 , p=4*2=8, num=110/10=11 then printsn d as 2
n=11 then rem =1 , d=2+1*8=10 , p=8*2=16 ,num=11/10=1 then prinrts d as 10
n=1 then rem=1, d=10+1*16=26 , p=16*2=32 , then num=1/10 then prints d as 26
out put is: 0,2,2,10,26
