A palindrome is a number or text phrase that reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 34543 and 11611. Write a program that reads in a five-digit integer and determines whether or not it is a palindrome.

Solving Steps:

Use integer division method (similar to the Excel Assignment Question 4) to solve the problem.

Part 2:

Write a program that checks whether the string given by the user is Palindrome or not.

A string can be said as a Palindrome in the case when you reverse the string and gives the same original string. For example think of a word like ABCCBA:

Original String: ABCCBA

Reverse String: ABCCBA

So both the original and the reverse match each other, so the string is a Palindrome.

In this problem only one word will be used and you need to check whether the word is a palindrome or not. Do not use any built-in functions; use the technique defined below.

How to check whether the string is palindrome or not:

str[0]    str1 [1]        str1 [2]          str1 [3]     str1 [4]      str1 [5]

A               B               C                  C                B            A

i=0                                                                                  j=5

Solving Steps:

Compare the character of str[i] and str[j]

Increment i++ (by 1) and Decrement j-- (by1)

Stops when i and j are equal or j<i
