C语言程序设计苏小红课后习题答案8.4 统计大于平均分人数

#define N 40
float Average(int arr[], int n);
int ReadScore(int score[]);

int main()
{
	int score[N],number=0;
	int n=ReadScore(score);
	int average=Average(score, n);
	for (int i = 0;i < n;i++)
	{
		if (average < score[i])
		{
			number++;
		}
	}
	printf("%d", number);

	return 0;
}

//计算平均分
 float Average(int score[], int n)
{
	int sum = 0.0;
	float average;
	int i;
	for (i = 0;i < n;i++)
	{
		sum = sum + score[i];
	}
	average = sum / n;
	return average;

}

//读取成绩
 int ReadScore(int score[])
{
	int i = -1;
	do
	{
		++i;
		scanf("%d", &score[i]);
	} while (score[i]>=0);
	
	return i;
}
