Give the output of the following program segment and also mention the number of times the loop is executed:
int a,b;
for (a = 6, b = 4; a <= 24; a = a + 6)
{
if (a%b == 0)
break;
}
System.out.println(a);
Answer
Output of the above code is 12 and loop executes 2 times.
Working
This dry run explains the working of the loop.
| a | b | Remarks |
|---|---|---|
| 6 | 4 | 1st Iteration |
| 12 | 4 | 2nd Iteration |
In 2nd iteration, as a%b becomes 0 so break statement is executed and the loop exits. Program control comes to the println statement which prints the output as current value of a which is 12.

Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.
Example1:
Input: 1021 output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4, NUMBER OF DIGITS = 4 ]Example2:
Input: 125 output: Not an SUPERSPY number [1+2+5 is not equal to 3]Rewrite the following do while program segment using for:
