输入5个数求他们中的最大值和平均值并输出

#include<stdio.h>
int main()
{

int a[5];int max;double avg; int sum = 0;
for (int i = 0; i < 5; i++)
{
	printf("请输入第%d个数\n",i+1);
	scanf_s("%d",&a[i]);
	max=a[0];
	sum += a[i];
    if(max<a[i])
	{  max = a[i];}
}
avg = sum / 5.0;
printf("最大值=%d\n",max);
printf("平均值=%2.2lf\n",avg);
return 0;

}
