Problem Description

输入一个百分制的成绩t，将其转换成对应的等级，具体转换规则如下：
90~100为A;
80~89为B;
70~79为C;
60~69为D;
0~59为E;

 

 

Input

输入数据有多组，每组占一行，由一个整数组成。

 

 

Output

对于每组输入数据，输出一行。如果输入数据不在0~100范围内，请输出一行：“Score is error!”。

 

 

Sample Input

56

67

100

123

 

 

Sample Output

E

D

A

Score is error!

#include<stdio.h>

int main()

{

    int n;

    while(scanf("%d",&n)!=EOF)

    {

                              if(n>=90&&n<=100)

                              printf("A\n");

                              if(n>=80&&n<=89)

                              printf("B\n");

                              if(n>=70&&n<=79)

                              printf("C\n");

                              if(n<=69&&n>=60)

                              printf("D\n");

                              if(n>=0&&n<=59)

                              printf("E\n");

                              if(n>100||n<0)

                              printf("Score is error!\n");

    }

    return 0;

}//注意写范围时是（n>=5&&n<=8）和平时数学的数学不一样。Hdu2004
