Even Odd Program with only integers of length 2 or higher

Write a C++ program in which a user enter a number, and the program will find the Even and odd number.

Your program should only accept integers of length 2 or higher and should ask the user to re-enter a value if the value containing total numbers of integers less than 2. The program with goto statement.

For example:

Integers with length 1: 1,2 ,3 ,4 ,5 ,6 ,7 ,8 ,9

Integers with length 2: 10, 11, 12 ,13 ,14 ,15 ,16 ,17 ,18 ,19, 20 ,……99

Integers with length more than 2: 100, 101, 102 ,103 ,……

Even Odd Program with only integers of length 2 or higher by using goto statement

#include <iostream>
using namespace std;
int main(){
   T4Tutorials:
    int num; 
	cout<<"Enter a number: "; 
	cin>>num;
 if (num>9)
//to ensure the length of number is at least 2
{
   if(num%2==0)
   { 
   cout<<"Even Number";
   }
   else 
   {
   cout<<"odd Number";	
   }
}
else
{
//to ensure that if the length of number is less than 2, then goto T4Tutorials albel (just
//below the main function) and again ask the user to enter the number.
	 goto T4Tutorials;
}
   return 0;
}
