Palindrome explain me also this code

Question

C++ Palindrome Numbers

If i put this 👇🏻 only test case 2,5,6 and then 1,3,4 case is coming wrong

#include <iostream>
using namespace std;

bool isPalindrome(int x)
{
//complete the function
int n,s=0,r;
x=n;
while(n!=0)
{ r=n%10;
s=s*10+r;
n=n/10;
}
}

int main() {
int n;
cin >>n;

if(isPalindrome(n)) {
cout << n<<" is a palindrome";
}
else {
cout << n<<" is NOT a palindrome";
}
return 0;
}

Answer 2

you doesn't return any value from isPalindrome function:

return s == x;

Answer 3

Abhishek Bairwa

Because you didn't return anything in your function.

So do this

return (x == s) //which will return true or false.

and change x = n to n = x

Answer 4

... or make n the function argument, and declare x instead of n:

bool isPalindrome(int n)
{
int x,s=0,r;

Answer 5

import java.util.Scanner; public class Pattern6 { public static void main(String[] args) { // Create a new Scanner object Scanner scanner = new Scanner(System.in); // Get the number of rows from the user System.out.println("Enter the number of rows to print the pattern "); int rows = scanner.nextInt(); System.out.println("** Printing the pattern... **"); for (int i = 1; i <= rows; i++) { for (int j = rows; j > i; j--) { System.out.print(" "); } for (int k = 1; k <= i; k++) { System.out.print(k + " "); } System.out.println(); } } }
