scanf("%d", &len);

//输入学生信息

for (i=0; i

scanf("%d ",&parr[i].age);

scanf("%f",&parr[i].score);

printf("name = ");

scanf("%s", parr[i].name);

}

//排序

printf("\n\n\n");

for(j=0; j

{for(k=0; k

{ if(parr[k].score > parr[k+1].score)

{ t = parr[k];

parr[k]=parr[k+1];

parr[k+1]= t;

}

}

}

printf("\n\n\n");

//输出学生信息

for (l=0; l

{ printf("age = %d\n", parr[i].age);

printf("score =%f\n ",parr[i].score);

printf("name =%s \n", parr[i].name);

}

return 0;

}

运行时到输入这一阶段，在age后就没下文了，不知道为什么
