   if(n==0){
      cout<<"NO input is entered!";
   }
   else{
      int oddCount = 0, evenCount = 0;
      while(n!=0){
         if(n>0){
             if(n%2==0){
                evenCount++;
             }
             else{
                oddCount++;
             }
         }
         cout<<"Enter number: ";
         cin>>n;
      }
      cout<<"Even count = "<<evenCount<<endl;
      cout<<"Odd count = "<<oddCount<<endl;  
   }
   return 0;
