给定一个奇数，求所有奇数的平均值

#include <stdio.h>
int main() {
   int n = 15,count = 0;
   float sum = 0;
   for (int i = 1; i <= n; i++) {
      if(i%2 != 0) {
         sum = sum + i;
         count++;
      }
   }
   float average = sum/count;
   printf("The average of odd numbers till %d is %f",n, average);
   return 0;
}

#include <stdio.h>
int main() {
   int n = 15;
   float average = (n+1)/2;
   printf("The average of odd numbers till %d is %f",n, average);
   return 0;
}
