往数组中输入数据，并通过 回车键 来确定输入的结束（提早结束输入）

[小城之光]

#include<iostream>
using namespace std;
const int max = 10;
int input_golf(double ar[]);
void show_golf(double ar[], int size);
double average_golf(double ar[], int size);

int main()
{
double golf[max];
int n;
n = input_golf(golf);
show_golf(golf, n);
double average;
average = average_golf(golf, n);
cout << "the average score is : " << average << endl;
return 0;
}

int input_golf(double ar[])
{
double score;
int i = 0;
cout << "please enter scores : " << endl;
cin >> score;
while ((cin.get() != '\n') && (i < max))
{
ar[i] = score;
cin >> score;
i++;
}
return(i);
}

void show_golf(double ar[], int size)
{
int i;
for (i = 0; i < size; i++)
{
cout << ar[i] << " ";
}
cout << endl;
}

double average_golf(double ar[], int size)
{
int i;
double sum = 0;
for (i = 0; i < size; i++)
{
sum += ar[i];
}
return(sum/size);
}
输入：8 9
输出：8
平均值：8

请教!为啥输出总比输入少一个数呃？

请参考以下修改

int input_golf(double ar[])
{
  double score;
  int i = 0;
  cout << "please enter scores : " << endl;
  //cin >> score;
  do//while ((cin.get() != '\n') && (i < max))
  {
    cin >> score;
    ar[i] = score;
  //cin >> score;
    i++;
  }while ((cin.get() != '\n') && (i < max));

  return(i);
}

[code=C/C++]

{
double score;
int i = 0;
cout << "please enter scores : " << endl;
//cin >> score;
while (i < max && cin >> score)
{
ar[i] = score;
//cin >> score;
i++;
}
return(i);
}

char s[1000];
fgets(s,1000,stdin);

多谢大家咧！ 不过只能采纳 #1楼 的修改方法了，因为想实现通过enter键来判断数组是否提早结束输入。
同时追问 #1楼，修改前后的区别在哪里？

[mujiok2003]

	cout << "please enter scores : " << endl;
	//cin >> score;
	while (i < MAX)
	{
		cin >> score;
		if(cin)
		{
			ar[i++] = score;
		}
		else //非法字母
		{
			break;
		}

	    if(cin.get() == '\n') //换行了
		{
			break;
		}
	}

i != '\n'就可以啊！
