[KUONSAMA]

#include <iostream>
using namespace std;
void main()
{
cout << "请输入十个数" << endl;
float average(float a[]);
float score[10];
for (int i = 0; i < 10; i++)
{
cin >> score[i];
}
cout << "average:" << average(score) << endl;
}
float average(float a[])
{
float sum = 0;
for (int i = 0; i < 10; i++)
{
sum = sum + a[i];
}
system("pause");
return(sum / 10);
}
