Implement the isPalindrome and numberOfVowels function after the main function
#include <iostream>
#include <cstring>
using namespace std;
bool isPalindrome(char s[20] );
int numberOfVowels(char s[20]);
int main() {
char str1[20]; // storage of string
cin >> str1; // input here

if (isPalindrome(str1))
cout << "Palindrome" << endl;
else
cout << "Not a palindrome" << endl;

cout << "No. of vowels: " << numberOfVowels(str1) << endl;

return 0;
