State the difference between entry controlled loop and exit controlled loop.
Answer
| Entry controlled loop | Exit controlled loop |
|---|---|
| It checks the condition at the time of entry. Only if the condition is true, the program control enters the body of the loop. | It checks the condition after executing its body. If the condition is true, loop will perform the next iteration otherwise program control will move out of the loop. |
| Loop does not execute at all if the condition is false. | The loop executes at least once even if the condition is false. |
| Example: for and while loops | Example: do-while loop |

Define a class to accept a number from user and check if it is an EvenPal number or not.
(The number is said to be EvenPal number when number is palindrome number (a number is palindrome if it is equal to its reverse) and sum of its digits is an even number.)
Example: 121 – is a palindrome number
Sum of the digits – 1+2+1 = 4 which is an even numberHow many times will the following loop execute? Write the output of the code:
