以下程序中函数f的功能是: 当flag 为1时，进行由小到大排序;当flag 为0时,进行由大到小排序。void f(int b[], int n, int flag){int i, j, t; for (i=0; i＜n-1; i++) for (j=i+1; j＜n; j++) if(flag ? b[!]＞[j]: b[i]＜b[j]) { t=b[i]; b[i]=b[j]; b[j]=t; }}main (){ int a[10]={5,4,3,2,1,6,7,8,9,10}, i; f(&am
选项：

B:3,4,5,6,7,2,1,8,9,10,
C:5,4,3,2,1,6,7,8,9,10,
D:10,9,8,7,6,5,4,3,2,1,
