有以下程序:#include ＜stdio.h＞void f(int * x,int * y)int t; t= *x; *x= *y; *y=t;main ( ){ int a[8] = { 1,2,3,4,5,6,7,8} ,i, * p, * q; p=a;q =&a[7]; while(p＜q) { f(p,q) ;p ++ ;q --; } for(i =0;i＜8;i ++ ) printf(" % d," ,a[i]); }程序运行后的输出结果是( )。
A．8,2,3,4.,5,6,7,1,
B．5,6,7,8,1,2,3,4,
C．1,2,3,4,5,6,7,8,
D．8,7,6,5,4,3,2,1,
