有以下程序void sort(int a[],int n){ int i,j,t; for(i=0;i<n-1;i+=2) for(j=i+2;j<n;j+=2) if(a[i]<a[j]) { t=a[i]; a[i]=a[j]; a[j]=t; }}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");}执行后的输出结果是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．1,10,3,8,5,6,7,4,9,2,
