this a good book.

#include <iostream>
using namespace std;

int main()
{
	int i,avg,min,max;
	int vn[5]={25,56,-22,43,4};
	avg=0;
	for( i=0; i<5; i++)
	/**********found**********/
		avg=vn[i];

	avg/=5;
	cout << "平均值是: " <<avg << endl;
	min=max=vn[0];
	for(i=0;i<5;i++)
	{
	/**********found**********/
		if(vn[i]>min) min=vn[i];
	/**********found**********/
		if(vn[i]<max) max=vn[i];
	}
	cout << "最小值是: " << min << endl;
	cout << "最大值是: " << max << endl;
	return 0;
