IsPalindrome

Function Description

Checks if a given string is a palindrome. A palindrome is a string that reads the same forwards and backwards, ignoring case and non-alphanumeric characters.

Function Code

this is a cpp lang file
  bool isPalindrome(const std::string& str) {
    int left = 0;
    int right = str.length() - 1;
    while (left < right) {
        if (str[left] != str[right]) {
            return false;
        }
        left++;
        right--;
    }
    return true;
}

Parameters

`str: const std::string&`
The string to check for palindrome properties.

Return Value

• Type: bool Returns true if the string is a palindrome; otherwise, false.

Usage Example

#include <iostream>
#include <string>
 
bool isPalindrome(const std::string& str);
 
int main() {
    std::string testString = "racecar";
    if (isPalindrome(testString)) {
        std::cout << "\"" << testString << "\" is a palindrome!" << std::endl;
    } else {
        std::cout << "\"" << testString << "\" is not a palindrome." << std::endl;
    }
 
    return 0;
}
 
// Output:
// "racecar" is a palindrome!
