 Q: Consider the following code fragment:int a = 6, b = 7, c = -3, result = 0; result += ++a - b++ + --c;Rewrite this code by decomposing the last line into several lines to make the code easier to understand. Hint: After execution of your modified code all variable must have identical values with respect to the original code. In other words: Your modifications shall not alter the code's behaviour in any way. A: Incrementing ++a and decrementing --c happens prior to adding / subtracting their values to the variable result (prefix notation). The increment operation b-- in contrast happens after being being subtracted from variable result (postfix notation). The following code snippet is thus equivalent: int a = 6, b = 7, c = -3, result = 0; ++a; --c; result += a - b + c; // or even: result = result + a - b + c; b++;
