问题:

解答:

#include <iostream>
using namespace std;

#define MAX 10

int input(float* grade, int len)
{
	int i = 0;
	for (i = 0; i < len; i++)
	{
		cout << "请输入第" << i + 1 << "个高尔夫成绩(按0结束):";
		cin >> grade[i];
		if (grade[i] == 0)break;
	}
	return i;
}

void print(float* grade, int len)
{
	cout << "高尔夫的成绩为:";
	for (int i = 0; i < len; i++)
	{
		cout << grade[i] << "  ";
	}
	cout << endl;
}


float average(float* grade, int len)
{
	double sum = 0;
	for (int i = 0; i < len; i++)
	{
		sum += grade[i];
	}
	return sum / len;
}

int main()
{
	float grade[MAX];
	int index = 0;
	float aver = 0;
	index=input(grade, MAX);
	print(grade, index);
	aver=average(grade, index);
	cout << "平均成绩为:" << aver << endl;

	return 0;
}

运行结果:

考查点:

• 函数
• 数组当函数参数
