X-=--x+ ++x - --x*2 if x = 6 – InterviewSolution

1.	X-=--x+ ++x - --x*2 if x = 6
Answer» ONG>Explanation: x = 3; x = ++x + (++x); ++x WOULD increase ‘x’ by ONE and use this value. If you add 1 to the current value of x, which is 3, then you have 4. x = 4 + (++x); ++x would increase ‘x’ by one again and use (again) this value. If you add 1 to the current value of x, which is 4, then you have 5. x = 4 + (5); Sum the remainders, and the SOLUTION of your question would be: x = 9.

X-=--x+ ++x - --x*2 if x = 6

Answer» ONG>Explanation:

x = 3;

x = ++x + (++x);

++x WOULD increase ‘x’ by ONE and use this value. If you add 1 to the current value of x, which is 3, then you have 4.

x = 4 + (++x);

++x would increase ‘x’ by one again and use (again) this value. If you add 1 to the current value of x, which is 4, then you have 5.

x = 4 + (5);

Sum the remainders, and the SOLUTION of your question would be:

x = 9.
