int main(int argc, char** argv) {
   double price[10]={96.5,100.5,100.5,100.5,99,99,99,100,98.5,98.9};
   double total = 0.0;
   double average = 0.0;
  
   for(int i=0;i<10;i++)
   {
       total = total + price[i];
   }
   average = total / 10;
   cout << fixed <<setprecision(2);
   cout << \"Average stock price:$\" << average <<endl;
