What will be the final value of the digit?void main(){ int digit = 0; ...
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
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

What will be the final value of the digit?void main(){ int digit = 0; ...
The provided code snippet is incomplete and does not specify the condition for the for loop. Without the condition, it is not possible to determine the final value of the digit variable.
