The output of the above code is:
a b c d
Working
The below table shows the dry run of the program:
| x | ch | Output | Remarks |
|---|---|---|---|
| 97 | a | a | 1st Iteration |
| 98 | b | a b | 2nd Iteration |
| 99 | c | a b c | 3rd Iteration |
| 100 | d | a b c d | 4th Iteration — As x%10 becomes true, break statement is executed and exists the loop. |
