问题:

解答:

#include <iostream>
#include <array>
using namespace std;

#define MAX 10

int main()
{
	array<float, MAX> arr;
	float sum=0;
	float average=0;
	int i = 0;
	int count=0;
	int bigger = 0;
	for (i = 0; i < MAX; i++)
	{
		cout << "请输入donation的值:" << endl;
		cin >> arr[i];
		if (cin.fail())
		{
			cout << "输入的非数字,结束输入!" << endl;
			break;
		}
		sum += arr[i];
		count++;
	}
	average = sum / count;
	for (int i = 0; i < count; i++)
	{
		if (arr[i] > average)
		{
			bigger++;
		}
	}
	cout << "这些数字的平均值为:" << average << endl;
	cout << "大于平均值的有" << bigger << "个" << endl;

	return 0;
}

运行结果:

考查点:

• if
• 计算
