写一个代码
总分100 分
90-100是等级A;
80-89是等级B；
70-79是等级C
60-69是等级D
0-50是等级E

#include<stdio.h>
void main()
{
   float fScore;
   printf("Plesae input your score:\n");
   scanf("%f",&fScore);
   

   if((fScore)>=90)；&&(fScore<=100))
      printf("Your score is A\n");
   else if(fScore>=80)
      printf("Your score is B\n");
   else if(fScore>=70)
      printf("Your score is C\n");  
   else if(fScore>=60)
      printf("Your score is D\n");
   else if(fScore>0)
      printf("Your score is E\n");
   else
      printf("You have no score !");
}






上面是我打好了的代码 可是却显示有个 error- -
  大家帮我看看 哪儿出错了
唉新人入门  啥子都不懂。。。

嗯 现在晓得问题在哪儿了  


   if (fScore>=90&&fScore<=100)
       printf("Your score is A\n");
