C Language: Judge whether a number of palindrome number (palindrome number is also a number, the character of the number is the positive and negative sequence is the same number, such as: 12321,3443) __c language

Palindrome number of the positive and negative sequence is the same number, so we put this number of high-low-level exchange, that is, 1234->4321, and then use the new number to compare with the previous digital exchange is equal, that is, can determine whether this number is a palindrome number. Note : Negative numbers are not palindrome numbers.

Judge whether a number of palindrome number (palindrome number is also a number, the number is characterized by positive and negative sequence is the same number, such as: 12321,3443)
