47) 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 “5d %dn”,s[1].Score,p[1]->Score);
}
执行后输出结果是
(A)550 550
(B)680 680
(C)580 550
