单选题 以下程序运行后的输出结果是(). 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); }
