hello, i really dont know why ?

to let you know what i intend to do , please read this question "

[Finding a palindrome number ]

"A palindrome is a number or a text phrase that reads the same backwards as forwards.

For example, each of the following five-digit integers is a palindrome: 12321, 55555,

45554 and 11611. Write a program that reads in a five-digit integer and determines

whether it is a palindrome. [Hint: Use the division and modulus operators to separate

the number into its individual digits.]"

after going through the usual way of separating of digits ... to show that if two numbers

(the original one and the new generated number) i used the logical And operator (&&) ..

so that if the two numbers are the same it would generate the number 1

which is considered true in C++ ... and if not ,, it will produce 0 that is False.

but when compiling the program . i always get "true" in loop continuation condition

and thus i fail ! i tried to use equality operator (==) to check

whether two numbers are the same , but again no luck ! i get that damn true in loop -continuation condition

!then after some time of contemplating i come up with the second solution ,

that only works with 5 digit numbers ! ( and im not fond of using it , cuz i think this kind of solution is not right , and it just doesnt feel good !

now i just wana know why this happens , and where i made my mistake ! and what is (or are ) my mistake(s) ...

any comment is greatly appreciated .

first snippets of code:

program number 2: using a very terrible way to solve the assignment !:Code://In the Name Of God /* 4.26 A palindrome is a number or a text phrase that reads the same backwards as forwards.

thanks a million in advance !Code://In the Name Of God /* 4.26 A palindrome is a number or a text phrase that reads the same backwards as forwards .

(by the way i use code::blocks 8.2 compiler )
