UC知道这个C语言怎么回事？总是出现不了order=1的情况，上来就从order=2开始

for(m=1;m<=M;m++)
{for(i=0;i<=(M-1);i++)
if(stu[i].ord==m)
printf("number:%s,subject 1:%d,subject 2:%d,subject 3:%d,average:%d,order:%d\n",stu[i].stn,stu[i].s1,stu[i].s2,stu[i].s3,stu[i].ave,stu[i].ord);}
问题在这里.当if的条件不满足时,下面语句不执行,内循环就结束了.应该加一句控制else continue;以使内循环执行完.
for(i=0;i<=(M-1);i++)
s1_sum+=stu[i].s1;
s1_ave=s1_sum/M;
for(i=0;i<=(M-1);i++)
s2_sum+=stu[i].s2;
s2_ave=s2_sum/M;
for(i=0;i<=19;i++) 对了.这里i<=19是怎么回事?
s3_sum+=stu[i].s3;
s3_ave=s3_sum/M;
