有以下程序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 ",s[1].Score,p[1]->Score);}程序运行后的输出结果是A．550 550 B．580 550 C．680 680 D．580 680
