8. What is the difference between the following if x is zero at the start of each statement? x += 1; x = x + 1; ++x; x++; 9. What is the difference between the following if x is zero at the start of each statement? cout << (x += 1); cout << ++x ; cout << x++; 10. What are the values if x = 1 and y = 2 for each set: y = x++; x: __________________ y: __________________ y = ++x x: __________________ y:
