Answer:
This program is written in C++
Note that the average is calculated without the highest and the least value.
Comments are used for explanatory purpose
See attachment for .cpp file.
Program starts here
#include<iostream>
using namespace std;
int main()
{
int num;
cout<<"Enter Number of Test [0-10]: ";
//cin>>num;
while(!(cin>>num) || num > 10|| num<0)
{
cout << "That was invalid. Enter a valid digit: "<<endl;
cin.clear(); // reset the failed input
cin.ignore(123,'\n');//Discard previous input
}
//Declare scores
int scores[num];
//Accept Input
for(int i =0;i<num;i++)
{
cout<<"Enter Test Score "<<(i+1)<<": ";
cin>>scores[i];
}
//Determine highest
int max = scores[0];
for (int i = 1; i < num; i++)
{
if (scores[i] > max)
{
max = scores[i];
}
}
//Determine Lowest
int least = scores[0];
for (int i = 1; i < num; i++)
{
if (scores[i] < least)
{
least = scores[i];
}
}
int sum = 0;
//Calculate total
for(int i =0; i< num;i++)
{
sum += scores[i];
}
//Subtract highest and least values
sum = sum - least - max;
//Calculate average
double average = sum / (num - 2);
//Print Average
cout<<"Average = "<<average<<endl;
//Print Highest
cout<<"Highest = "<<max<<endl;
//Print Lowest
cout<<"Lowest = "<<least;
return 0;
