Hi,
That's better. You got it right this time - congradulations.
One more note though, As Jacob said, it'd be helpful (for both you and your
computer) if you enclose the addition in parentheses (called operator
precedence). This will make sure that the addition happens first followed by
division, like:
answer = (score_1+score_2+score_3)/3;
Also, bare in mind that if you get the answer, the decimal prt i.e. the one
after the period would be gone. To avoid it, declare the answer variable as
a double.
Cheers,
Joseph P.S. Good job this time.

#include <iostream>
using namespace std;

double score_1=0;
double score_2=0;
double score_3 (0);
int answer;

out the average for you. ";
cout<< "Please enter your first test score, then press enter. Decimal values
accepted: " ;
cin >> score_1 ;
cout<< "Please enter your second test score. Remember to press enter when
done: ";
cin >>score_2 ;
cout<< "Finally, enter your third test score.";
cin >>score_3 ;
answer = score_1+score_2+score_3/3;
cout<<"The average is " <<answer;
return (0);
} //end of main function.
