求和用的float初始化，最后40分

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<math.h>
int main()
{
    int n = 0;
    int k = 0;
    scanf("%d%d", &n, &k);
    int x = 0;
    float s1 = 0;
    float s2 = 0;
    int count1 = 0;
    int count2 = 0;
    for (int i = 1; i < n+1; i++)
    {
        if (i%k == 0)
        {
            count1++;
            s1 = s1 + i;
        }
        else 
        {
            count2++;
            s2 = s2 + i;
        }
    }
    printf("%.1lf %.1lf", s1 / count1, s2 / count2);
    /*printf("%.1lf %.1lf", s1*1.0 / count1, s2*1.0 / count2);*/
    return 0;
}
