【C++ Primer Plus习题】7.2

问题:

解答:

#include <iostream>
using namespace std;#define MAX 10int 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
