NOTE DONTT USE AI I WILL GIVE MULTIPLE DISLIKES AND IWILL REPORT THE ANSWER

Here's a C$++$ code snippet with some potential issues. I've also provided a question at the end, asking you to identify and fix the issues.

Code:

#include

using namespace std;

class NumberOperations $\{$

private:

int number;

public:

NumberOperations$($int n$)\{$

number $=$ n;

$\}$

$//$ Function to check if the number is prime

bool isPrime$()\{$

if $($number $<=1)$

return false;

for $($int i $=2$; i $<=$ number $/2$; i$++)\{$

if $($number $\%$ i $==0)$

return false;

$\}$

return true;

$\}$

$//$ Function to get the factorial of the number

int factorial$()\{$

if $($number $<0)$

return $-1$; $//$ Negative numbers don't have factorial

int result $=1$;

for $($int i $=1$; i $<=$ number; i$++)\{$

result $*=$ i;

$\}$

return result;

$\}$

$//$ Function to calculate the sum of digits

int sumOfDigits$()\{$

int sum $=0$;

int temp $=$ number;

while $($temp $>0)\{$

sum $+=$ temp $\%10$;

temp $/=10$;

$\}$

return sum;

$\}$

$//$ Function to reverse the number

int reverseNumber$()\{$

int reversed $=0$;

int temp $=$ number;

while $($temp $>0)\{$

reversed $=$ reversed $*10+$ temp $\%10$;

temp $/=10$;

$\}$

return reversed;

$\}$

$//$ Function to check if the number is a palindrome

bool isPalindrome$()\{$

return number $==$ reverseNumber$()$;

$\}$

$\}$;

int main$()\{$

int num;

cout $<<$ "Enter a number: $"$;

cin $>>$ num;

NumberOperations numOps$($num$)$;

cout $<<"$Is the number prime? $"<<($numOps$.$isPrime$()?$ "Yes" : $"$No$")<<$ endl;

cout $<<$ "Factorial: $"<<$ numOps.factorial$()<<$ endl;

cout $<<$ "Sum of digits: $"<<$ numOps.sumOfDigits$()<<$ endl;

cout $<<$ "Reversed number: $"<<$ numOps.reverseNumber$()<<$ endl;

cout $<<"$Is palindrome? $"<<($numOps$.$isPalindrome$()?$ "Yes" : $"$No$")<<$ endl;

return $0$;

$\}$

Question:

This code performs several operations on a number input by the user. However, there are some issues and improvements that can be made. Review the code and address the following questions:

$1.$ Identify any issues or potential errors in the factorial function when the number is too large.

$2.$ The isPrime function can be optimized. How would you improve the loop to reduce unnecessary checks?

$3.$ There$$s an issue with the factorial function for negative inputs. Modify it so that it properly handles negative input cases.

$4.$ Can you suggest an improvement to the reverseNumber function to handle negative numbers?
