Answer 1

#include "stdio.h"

int main(int argc,char *argv[]){

int a[10][2]={{2018101,60},{2018102,88},{2018103,86},{2018104,75},

{2018105,98},{2018106,65},{2018107,93},{2018108,79},

{2018109,83},{2018110,84}},t[][2]={{0,90},{0,81},{0,93},{0,94}},i,j,k,r;

printf("\nCompetition at the provincial level stu-number is as follows:\n");

for(r=i=0;i<10;i++)//求参加省竞赛人员并获得省竞赛成绩

if(a[i][1]>85)

printf("\t%d\n",t[r++][0]=a[i][0]);

for(i=0;i<r;i++){//对省竞赛成绩由高到低排序

for(k=i,j=k+1;j<r;j++)

if(t[k][1]<t[j][1])

k=j;

if(k!=i)

j=t[k][0],t[k][0]=t[i][0],t[i][0]=j,j=t[k][1],t[k][1]=t[i][1],t[i][1]=j;

}

printf("\nThe national competition students stu-number is as follows:\n");

for(r=int(0.3*r+0.5),i=0;i<r;i++)

printf("\t%d\n",t[i][0]);

return 0;

}

能帮忙加个注释吗。有点看不太懂
