C语言：编这样一个程序，用户输入10个整数，程序找出其中的最大值和最小值

#include<stdio.h>
#include<stdlib.h>

void MaxMin(int arr[],int len)
{
int Max = 0;
int Min = 0;
int i = 0;

for (; i < len - 1; i++)
{
if (arr[i] >= arr[i + 1])
{
Max = arr[i];
arr[i + 1] = Max;
}
}

for (i = 0; i < len - 1; i++)
{
if (arr[i] <= arr[i + 1])
{
Min = arr[i];
arr[i + 1] = Min;
}
}

printf("Max = %d\n", Max);
printf("Min = %d\n", Min);
}

int main()
{
int arr[] = { 1, 54, 23, 34, 65, 87, 67, 45, 12, 10 };
int size = sizeof(arr) / sizeof(arr[0]);
MaxMin(arr, size);
system("pause");
return 0;
}
