What is the output of the following code?
```
int x = 0;
while (x < 4) {
x = x + 1;
}
System.out.println("x is " + x);
```
a. x is 0
b. x is 1
c. x is 2
d. x is 3
e. x is 4
e. x is 4
x is 0 before the loop. The loop is executed 4 times for x from 0 to 3. When x is 4 the loop exits. So, the correct answer is E.
