Line 21:

fact=fact*i;

fact is not a variable. It's the address of your function i.e. a pointer.

#include <iostream>

long fact(long number);

int main()
{
   long number = 0;

   std::cout << "enter the number: ";
   std::cin >> number;

   std::cout << "factorial of " << number << " is " << fact(number) << "\n";
}


long fact (long number)
{
   long fact = 1;

   for (int i = 1; i <= number; i++)
   {
      fact *= i;
   }

   return fact;
}
