找出数组最大值

void SortArray()
{
	int arr1[5] = { 2,5,3,1,4 };
	int len = 5;
	int k = 0;
	while(k<len-1)
	{
		for (int i=0;i<len-1-k;i++)//每次循环最大值被选出，故可以省略一次循环:len-1-k
		{
			if (arr1[i] > arr1[i + 1])
			{
				int t = arr1[i];
				arr1[i] = arr1[i + 1];
				arr1[i + 1] = t;
			}
		}
		k++;
	}
	for (int x=0;x<len;x++)
	{
		printf("%d", arr1[x]);
	}
}
