Question

(Java expressions) What do the following statements do?

i++;

i += 2;

i /= 10;

Answer 1

The following ststements perform the following action:-

In all the cases we assume we have created a variable i in the program.

1. When we write i++, we ask the system to add 1 to the value of i (variable) in a given loop.

2. i += 2

When we write i+=2, what we mean is i = i + 2.

3. i /= 10

When we write i/= 10, what we mean is i = i / 10
