我试图通过一个函数传递一个简单的数组来计算平均值。
int main()
{
int n = 0; // the number of grades in the array
double *a; // the array of grades
cout << "Enter number of scores: ";
cin >> n;
a = new double[n]; // the array of grades set
// to the size of the user input
cout << "Enter scores separated by blanks: ";
for(int i=0; i<n; i++)
{
cin >> a[i];
}
computeMean(a, n);
}
double computeMean (double values[ ], int n)
{
double sum;
double mean = 0;
mean += (*values/n);
return mean;
}
现在代码只取最后输入的数字的平均值。
