发帖数: 286 | 3 一个很简单的 stream input 小程序，目的是读入名字，ID号码，及其它信息。
我的问题是，如果先读入名字，再读入 ID，就一切正常，可是如果先读入 ID，在读名
字的时候，就会自动跳过，不让我输入名字了。我的程序如下：
#include
using namespace std;
int main()
{
unsigned idNumber;
char firstName[30];
int hoursWorked;
char ch = '\0';
int i = 0;
cout << "Please enter your first name: ";
while (1) {
cin.get(ch);
if (ch == '\n') break;
firstName[i++] = ch;
}
firstName[i] = '\0';
cout << "Please enter your ID Number: ";
cin >> idNumber;
cout |
|

发帖数: 436 | 4 把 cout << endl;换成 cin.get();
因为cin >> idNumber;中idNumber只接受了数字，而把"\n"符剩下了。 |

，说是nexgen比绿墙的好用些。楼上BIBO说的bluecross那个保险是很讨厌，他们4月1
号退出medco之后，IDnumber后面一定要输入01（cardholder），或02.。。。有时候
cardholder要输51，或是53.。。反正有些乱。记得4月初的时候，因为这个改动，搞得
很麻烦，有些是电脑自动改，有些不是，每次还要病人拿新的insurance card过来。。
。。
我也是觉得insurance比较难搞定，这些学校又不交的。药剂师也就说这个需要经验。
但是还是希望有哪位前辈能够总结一下 |
