Question

Write a program that prompts the user to enter a three digit integer and determine whether it is a palindrome number.

Answer 1

You never said what language to use so here is your answer in Javascript:

<script type="text/javascript">
function checkPal() {
    var reversestr = "";
    var str = window.prompt("Enter a 3 digit number: ");
    var i = str.length;

    for(var j=i; j>=0; j--) {
        reversestr = reversestr+str.charAt(j);
    }
    if(str == reversestr) {
        alert(str+" Is Palindrome");   
    }
     else {
        alert(str+" Is not a Palindrome");
    }
}
checkPal();
</script>
