Answer: Option C
Solution (By Examveda Team)
First of all for loop have no braces so for loop on have only next line in its body.for( ; digit <= 9; )
digit++;
After completing for loop digit = 10;
next statement digit *= 2; i.e digit = digit * 2 = 20;
next statement digit--; i.e 20-- => 19
So final value of digit is 19

Digit got increamented until it became 9 then at last it got increamented to 10 then condition got false and loop terminated.
Digit *= 2 resulted in Digit = 20
-- Digit resulted in Digit = 19
