count++;
}
}
System.out.println(count);

What is printed as a result of executing the code segment

Answer 1

The code segment with nested loops prints the number 10 after counting the total number of passes through the inner loop.

Step-by-step explanation:

The code segment is an example of nested loops in programming. The outer loop runs four times, for x values from 0 to 3. The inner loop starts with y = x and runs until y is less than 4. The variable count is incremented once for every pass of the inner loop.

For every iteration of x, the inner loop iterations are as follows:

• When x is 0, y runs from 0 to 3 (4 times)
• When x is 1, y runs from 1 to 3 (3 times)
• When x is 2, y runs from 2 to 3 (2 times)
• When x is 3, y runs just once (1 time)

Adding these up, count is incremented 4 + 3 + 2 + 1 = 10 times. Therefore, the printed result is 10.
