Hi benjamin 8 welcome to DaniWeb.
What is there to explain?
Strictly speaking C# uses methods, not functions.
If you know how to reverse a string and how to compare a string, this is easy.
If you have any trouble, please show us your code and point out the difficulties you are having.
Thank you, Dani.
Well, I am a beginner.
In some other languages, you could create a function and then call it in your main program.
We are not allowed to use built-in functions, and there lies my problem. Any ideas with what else I could do?
Hi Benjamin! You could impress your teacher with this (needs using System.Linq at the start):
public bool isPalindrome(string aString)
return aString.Contains(new string(aString.Reverse<char>().ToArray<char>()));
Seriously. A string is an array of characters. Loop that array (i.e. string) by comparing first and last characters, then second character and second last character. As long as they are the same, you have a palindrome. When you encounter a mismatch, the string is not a palindrome.
