有以下程序:
void sort(int a[],int n)
int i,j,t;
for(i=0;i＜n-1;i+=1)
for(j=1+2;j＜n;j+=2)
if(a[i]﹤a[j])t=a[i];a[i]=a[j];a[j]=t;

void main()
int aa[10]= 1,2,3,4,5,6,7,8,9,10 ,i;
sort(aa,10),
for(i=0;i＜10;i++) printf("%d,",aa[i]);
printf("\n")；

A．1,2,3,4,5,6,7,8,9,10,

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

D．9,10,7,8,5,6,3,4,1,2,
