该程序代码是求数组平均值问题,采用递归算法实现.

#include "iostream.h"
double average(double a[],double aver,int m,int n)
{
	if(m<=n)
	{
		aver=(aver*(m-1)+a[m])/m;
		return average(a,aver,m+1,n);
	}
	else
		return aver;
}
void main()
{
	int n,i;
	double aver;
	double a[100];
	cin>>n;
	for(i=1;i<=n;i++)
		cin>>a[i];
	aver=average(a,0,1,n);
	cout<<aver<<endl;
}
