解题思路:
注意事项:
while(score!=0&&score!=-1)
{
scanf("%f",&score);
if(score>=85) count1++;
else if (score>=60) count2++;
else if (score!=0&&score!=-1) count3++;
}
注意不要使输入的-1或者0 被统计其中
参考代码:
#include <stdio.h> int main() { float score=1; int count1=0,count2=0,count3=0; while(score!=0&&score!=-1) { scanf("%f",&score); if(score>=85) count1++; else if (score>=60) count2++; else if (score!=0&&score!=-1) count3++; } printf(">=85:%d\n",count1); printf("60-84:%d\n",count2); printf("<60:%d\n",count3); return 0; }
