Judges scores

[Tycose2014]

This is a homework problem, but the only problem I am having trouble with is taking 5 scores, getting rid of the highest and lowest, then averaging out the rest. In the snippet below, it is only taking the last number entered, but not the rest. I have figured this out by reversing the numbers in different orders.
Not asking this to be solved, but where do I need to look. The score range is 0-10, largest is set at 0 and smallest is set at 11 (to allow everything else to be smaller initially.)

  sum = 0;
		for (int z = 1; z <= 5; z++) {

				cout << "Enter score #" << z << "." << endl;
				cout << fixed << setprecision(2);
				cin >> a;
				
				if (a <= 10 && a >= 0) {
					if (a > largest) {
						largest = a;
					}
					if (a < largest) {
						smallest = a;
					}
					if (a < smallest) {
						smallest = a;

					}

				}
				else {
					cout << "Please try again. " << endl;
				}
sum += a;
			}

int largest = 1 , smallest = 0 ;

if( a > largest )
{
       largest = a ;
}
else if( a < smallest )
{
       smallest = a ;
}
else if( smallest < a && a < largest )
{
       sum += a ;
       average = sum / z ;
}
 

tycose2014 excuse, if I translated correctly, you mean the average of the numbers between the smallest and largest, excluding the extremes themselves. then you should enter another variable, int average ..
