C语言小白求教,为什么平均值的运行结果为100而不是101

Question

```# include <stdio.h>

int main ()


{
    int i , average , sum = 0 ,count = 0 ;

    for (i=1;i<=100;i++)
    {   sum = sum + i ;
        count = count + 1 ;
    }
    average = sum / count ; 

    printf("sum = %d\ncount = %d\naverage = %d\n",sum,average,count);


    return 0 ;

}

Answer 1

平均值应该是50，不是100也不是101

正常计算结果为：50.5

average类型为int

转换结果为50
