多谢各位先
因为回国落下了最初的课程，现在回到学校，突然要交作业，简直是一头雾水！
从来没学过C语言，不知道为什么这学期刚开始，就搞这么难的来折磨人。。。。。
求求众大侠，帮帮忙吧！！！！

第二个表格：
 #include<stdio.h>
main()
{int score,n;
 printf("Infinity Business College\n");
 printf("Student results\n");
 printf("Please enter students grade:");
 scanf("%d",&score);
 if(90<=score&&score<=100)n=8;
 if(0<=score&&score<=30)n=3;
 if(score>30&&score<90)n=score/10;
 else printf("error");

  switch(n)
 {case 8: printf("The student received a grade A\nExecllent Work");break;
  case 7: printf("The student received a grade B\nWell Done");break;
  case 6: printf("The student received a grade C\nGood");break;
  case 5: printf("The student received a grade D\nSatisfactory");break;
  case 4: printf("The student received a grade E\nMust Try Harder");break;
  case 3: printf("The student received a grade F\nPoor");break;}}

thank you!!!!!
