how to print palindrome number in c++ code example
Example 1: check if a string is palindrome cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
string s;
cin >> s;
int l = 0;
int h = s.length()-1;
while(h > l){
if(s[l++] != s[h--]){
cout << "Not a palindrome" << endl;
return 0;
}
}
cout << "Is a palindrome" << endl;
return 0;
}
Example 2: next palindrome number in cpp
#include <iostream>
bool isPalindrome (int number) {
int decomposed = number, reversed = 0;
while (decomposed) {
reversed = 10 * reversed + (decomposed % 10);
decomposed /= 10;
}
return reversed == number;
}
int nextPalindromicNumber (int number) {
while (!isPalindrome(++number));
return number;
}
int main () {
int testCases;
std::cin >> testCases;
while (testCases--) {
int number;
std::cin >> number;
std::cout << nextPalindromicNumber(number) << '\n';
}
}
