@usha
If num =3 \* 3! = 6 *|
i=1 , f=1
Executes the for loop now i=1, 1<=3,post increment so i= 2 for next time
f= f*i =1*1 =1 --------returns f as 1
Next time after for loop
1*2 = 3-------------returns f as 2
After for loop
2*3 = 6 ---------------returns f as 6
Now for loops get failed in condition
So f=====6 \* ans *\
