How do you check if a string is a palindrome C++?

2. ith character is the same as ‘length-i-1’th character.

How do you get the length of a string in C++?

How do you find palindromes?

Palindrome number algorithm

1. Get the number to check for palindrome.
2. Hold the number in temporary variable.
3. Reverse the number.
4. Compare the temporary number with reversed number.
5. If both numbers are same, print “palindrome number”
6. Else print “not palindrome number”

Calculate Length of String without Using strlen() Function Here, using a for loop, we have iterated over characters of the string from i = 0 to until ‘\0’ (null character) is encountered. In each iteration, the value of i is increased by 1. When the loop ends, the length of the string will be stored in the i variable.
