Enter a no: 64
The entered no is:64
Remainder is 0
It is an even no!
#include <iostream>
using namespace std;


//Odd or Even no


int main() 
{

int x;

cout<<"Enter a no:\n";
cin>>x;
cout<<"The entered no is:"<<x<<endl;


switch(x%2)
{
    case 0:   

    cout<<"Remainder is 0"<<endl;
    cout<<"It is an even no!";
    break;
    
    case 1:
 
    cout<<"Remainder is 1"<<endl;
    cout<<"It is a odd no!";
    break;
    
    default:
    cout<<"Invalid no!";
}
    return 0;
