ALMOST DONE.. LITTLE HELP please!

#include <iostream>

    cout << "Average: " << totalAverage[day]/NUM_MONKEYS << endl;
}[/B]
//


    for (monkey = 0; monkey < NUM_MONKEYS; monkey++)
{
    for (day =0; day< NUM_DAYS; day++)
    {
        if ((average [monkey][day]) > highest)       //ESTE ESTA BIEN SEGUN YO ASI
        highest = average [monkey][day];
    }
//
}
     for (monkey = 0; monkey < NUM_MONKEYS; monkey++)
{
    for (day =0; day< NUM_DAYS; day++)
    {
    if ((average [monkey][day]) < lowest )                    // PERO ESTE ES EL DEL LOWEST Y PUES NOSE :S 
    lowest = average [monkey][day];
}
//
}
  cout << fixed << showpoint << setprecision (2);    // PARA QUE SEA DECIMAL POR EL DOUBLE

cout << "The highest amount is: " << highest << endl;
cout << "The lowest amount is: " << lowest << endl;    
    
      
         system ("PAUSE");
         return 0;
} 

WHEN YOU RUN and enter all the values, the part where the loop that say: cout << "Average of the three monkeys per day from day 1 to day 7\n"; does the average correct but on the third or fifth goes with power e
