有以下程序： #include ＜stdio.h＞ struct STU { char name[10];int num;int Score; }; main() { struct STU s[5]={{"YangSan",20041,703},{"LiSiGuo",20042,580}, {"WangYin",20043,680},{"SunDan",20044,550}, {"Penghua",20045,537}}, *p[5],*t;int i,j;for(i=0;i＜5;i++) p[i]=&s[i];for(i=0;i＜4;i++) for(j=i+1;j＜5;j++)if(p[i]-＞Score＞p[j]-＞Score){ t=p[i];p[i]=p[j];p[j]=t;}printf("%d%d\n",s[1].Score,p[1]-＞Score); } 执行后的输出结果是( )。
A．550 550
B．680 680
C．580 550
D．580 680
