Now that we have established this, let's break the program down. At the start of your program, x = 20. So, ++x would return 21. Now when you increment x in this fashion again, you will be incrementing 21 and not 20. WebStep 1: int x=4, y, z; here variable x, y, z are declared as an integer type and variable x is initialized to 4. Step 2: y = --x; becomes y = 3; because (--x) is pre-decrement operator. Step 3: z = x--; becomes z = 3;. In the next step variable x becomes 2, because (x--) is post-decrement operator. bookpeople co uk
