对于给定的百分制成绩，输出相应的A，B，C，D，E等级

#include <stdio.h>

void main ()

{
int score,temp,logic;
char grade;
logic=1;
while(logic)
{
printf("Input score:");
scanf("%d",&score);if ((score>100)||(score<0))
printf("|n Error,Input again!\n");
else
logic=0;
printf("\n");
}
if (score==100)
temp=9;
else
temp=(score-score%10)/10;
switch(temp)
{
case 9: grade='A';break;

    case 8: grade='B';break;

    case 7: grade='C';break;

    case 6: grade='D';break;

    case 5: 

    case 4: 

    case 3: 

    case 2: 

    case 1: 

    case 0: grade='E';
}
printf("score is %d,the grade is %c.\n",score,grade);

}
