This is my HW question:

Write a program that will ask the user to input 10 non-negative numbers. Your program should reject the number if it is negative, and make the user type a non-negative number. Your program should then compute and report the following statistics about the numbers entered: sum of the numbers, average of the numbers, # of odd numbers entered, # of even numbers entered.

I need help getting the total number of odd and even numbers this is what I have ...help please?

Code:
#include< iostream>
 #include <cmath>
 Using namespace std;
  
 int main ()

 {
  
 int a,b,c,d,e,f,g,h,i,j;
 int sum,avg,even,odd;
  
 cout << “Input ten non-negative numbers: ”
 cin >> a >> b >> c >> d >> e >> f >> g >> h >> i >> j;
  
 sum=a+b+c+d+e+f+g+h+i+j;
 avg= sum/10


    
       if ( a,b,c,d,e,f,g,h,i,j % 2 == 0 )
          cin>>even<<endl;
      else
           cin>> odd<< endl;


             if (a,b,c,d,e,f,g,h,I,j>=0)
             cout <<sum<<" " <<avg<< " "<<odd << " "<<even;
  
             else (a,b,c,d,e,f,g,h,i,j <0)

             cout << "You entered a negative number! ";
  
  
  
 return 0;
 }
I Greatly Appreciate Your Help =]
