Matching numbers

I'm trying to finish a homework assignment and I can't find this anywhere. I'm trying to match input numbers with randomly generated numbers and displaying how many of the 5 are correct(also with a win/lose message) This is what I have so far and any help would be appreciated. :)

#include <iostream>
 #include <cstdlib>
 
 using namespace std;
 
 
 
 void main()
 {
 //variables
 int lottery[5], user[5];
 int count = 0;
 int num1, num2, num3, num4, num5;
 int winnum;
 //generating numbers
 for (int i=0; i <5; i++)
 {
     lottery[i] =1+rand()%9;
 }
 //input
 cout << "Enter a digit between 0-9: ";
 cin >> num1;
 cout << "Enter a digit between 0-9: ";
 cin >> num2;
 cout << "Enter a digit between 0-9: ";
 cin >> num3;
 cout << "Enter a digit between 0-9: ";
 cin >> num4;
     cout << "Enter a digit between 0-9: ";
 cin >> num5;
 
 
 winnum = rand();
 
 //for (int i=0; i<5; i++)
 //  cin >> user[i];
 
 //display
 
 
 cout << "Winning Lottery Numbers: " << winnum << endl;
 
 cout << "Your ticket Numbers: " << num1 << num2 << num3 << num4 << num5 << endl;
 
 
 
 
 //matching the numbers
 
 //HELP!
 system("pause");
 
  }
