Correct Answer

Explanation

Let's analyze the given Java code step by step to determine its output:

Code:


char ch;
int x = 97;

do {
    ch = (char) x;
    System.out.print(ch + " ");
    if (x % 10 == 0)
        break;
    ++x;
} while (x <= 100);
        

Explanation:

  1. Initialization:

    - x starts at 97.
    - In ASCII, 97 corresponds to the character 'a'.

  2. Loop Execution:

    First Iteration:
    - ch = (char) x converts x to the character 'a'.
    - System.out.print(ch + " "); prints 'a'.
    - x % 10 for 97 is 7 (not zero), so the break statement is not executed.
    - ++x increments x to 98.

    Second Iteration:
    - ch = (char) x converts x to the character 'b'.
    - System.out.print(ch + " "); prints 'b'.
    - x % 10 for 98 is 8 (not zero), so the break statement is not executed.
    - ++x increments x to 99.

    Third Iteration:
    - ch = (char) x converts x to the character 'c'.
    - System.out.print(ch + " "); prints 'c'.
    - x % 10 for 99 is 9 (not zero), so the break statement is not executed.
    - ++x increments x to 100.

    Fourth Iteration:
    - ch = (char) x converts x to the character 'd'.
    - System.out.print(ch + " "); prints 'd'.
    - x % 10 for 100 is 0, so the break statement is executed, terminating the loop.

Conclusion:

The final output of the code is:

  • a
  • b
  • c
  • d
