#include <iostream>
using namespace std;
int main( )
{
int testscore = 0;
int num_test = 0;
double avg_testscore = 0.0;
double total_test = 0.0;
cout << "Enter test score [-1 to stop]: ";
cin >> testscore;
while (testscore != -1)
{
total_test = total_test + testscore
num_test = (num_test) + 1.0;
cout << "Enter next test score [-1 to stop]: ";
cin >> testscore;
}
avg_testscore = total_test / num_test;
cout << "Number of test taken: " << num_test << endl;
cout << "Total scores entered: " << total_test << endl;
cout << "Average score of people taking test: " << avg_testscore << endl;
system("pause");
return 0;
}

system("pause");
return 0;
}
basicly im taking the test score then entering the number of test total test is the sum of all scores entered so far and avg score is just that total / number of people taking test
An int cannot have any decimal values, so when you divide total_test / num_test, it rounds the number.
If you declare test_average as a double then it should fix your problem.
