A number is said to be palindrome if it reads both forward and backwards same. Example- 175571 454 A program for palindrome number can be made by simply extracting digits of the number in reverse order and adding them with their place value and then checking is it same as the original number or not. To extract a digit in revers order and adding with place value we simply follow the below code. while(n>0) { int d=n%10; rev=(rev*10)+d; n=n/10; } To explain this let us take an example 657 Then For first iteration = n=657 d=657%10=7 rev=(0*10)+7=7 For second iteration = n=65 ...
