need help with decimal places

[collegegirl101]

I need to average 5 test scores (0, 92.8, 100, 100, 100) and i have to get an average of 78.6 but i keep getting 78.56. I also need the average of 100, 100, 100, 100, and 105 and my output has to be 101.0 instead i just get 101.

It sounds like your real question is this:

How can I output a value to one decimal place?

#include <iomanip> at the top, change line 41 to: cout << "Average: " << fixed << setprecision(1) << average << endl;

I've seen
std::fixed << std::showpoint << std::setprecision(1)
also. Not sure if std::showpoint is needed.
