unsigned reverse (unsigned num) {
unsigned rev = 0;
while (num) {
rev *= 10;
rev += num % 10;

How do you know that a numeric is palindrome or not using c or pascal language?
Reverse the digits then check of the new number is the same as the original number.
Could you please tell me the Palindrome number checking code?
The most efficient method is to reverse the digits in the number and then check if the reversed number is equal to the original number. In C, we can implement this as follows (using long-hand notation for clarity). Note the use of base (defaulting to base 10) so that we can check values in other bases. bool is_palindrome (unsigned num, unsigned base = 10) { // local variables unsigned rev, digit, digits; // copy the input number digits = num; // initialise the accumulator rev = 0; // repeat while there are digits while (digits) { // extract the low-order digit using modulo (%) operator digit = digit % base; // shift the accumulated digits (if any) one position to the left rev = rev * base; // add on the new digit rev = rev + digit; // shift the remaining digits one position to the right digits = digits / base; } // end while // return true if the number and its reverse are equal return num == rev; }
