What will be the final value of the digit?
void main()
{
   int digit = 0;
   for( ; digit <= 9; )
   digit++;
   digit  *= 2;
   --digit;
}

Answer & Solution
Correct Answer: Option C
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
