Question

1. int x; x = (7 <= 6 && 'A' < 'F') ? 4 : 3

4. what is the output of the Java code below

int i;

for (i = 1; i <= 15; i++);

System.out.print(i + " ");

Explanation / Answer

1. Based on code, value of x is 3 as the condition before '?' evaluates to false.

2. C is true. While is a pre-test loop. The condition gets checked before loop body is executed, and also after the loop body is executed, to check whether next iteration should take place or not.

3. True, = is used for assignment, and == for comparison.

4. Output would be: 16

The loop is an empty loop and it terminates when the condition "i<=15" evaluates to false, and that is when i=16.
