Inputs and rest of the debug
Difficulty = 6
Scores[0] = 0
scores[1] = 1
.
.
scores[4] = 4
highest = 4,
lowest = 0,
total = 1+2+3+4 = 10
sum = total - highest - lowest = 10 - 4 - 0 = 6
score =sum * difficult = 6 * 6 = 36
not sure about the error, I don't think it is related to your code, may be you have configured VS wrong.
Change inputScores to,
void inputScores(double scores[])
{
for(int i = 0; i < 5; i++)
{
cout << "Please enter the score from Judge #" << i + 1 << ": ";
cin >> scores[i];
}
}
for inputs.
change
count<=5 to count<5 in determine lowest score
Will you code work if all the values are above 99999.0 or all the values are less than -1?
If you want them to work with all the values , assign first score to highest/lowest :)
How did you get it to equal 42.55. I am working on this same program trying to debug it and can't get it to equal 42.55.
wondering why you using
for(int i = 1; i < 5; i++) and
for(int i = 0; i < 5; i++) and
for(int i = 0; i <= 5; i++) ....they all should same ideally 0 to < 5 if size is 5
instead of hard code 5, just use scores.size(),,,,,,done
Here is my program. It should equal 42.55. It's not dropping the lowest score.

void inputScores(double scores[]) should return double[] values......array is not passed by reference ..so change function as:
double[] inputScores(double scores[])
{
for (int i = 0; i < 5; i++)
{
cout << "Please enter the score from Judge #" << i + 1 << ": ";
cin >> scores[i];
}
return scores;
}
and judgeScores = inputScores(judgeScores); .and call other methods....will work
Debbie did you ever get this to work
I think so. I changed this part:
double findHighScore(double scores[])
{
double highest = 0;
to:
double findHighScore(double scores[])
{
double highest = 99999.0;
Still unable to get it to work.. can you attach your whole program to compare to what I have
This is what I have, let me know if it worked for you.
