这是一个很奇怪的问题,当我的程序向用户询问地址时,而不是等待输入,似乎完全跳过了getline()函数
Answerinput:
cout << "would you like to add another entry to the archive? (Y/N):";
cin >> answer;
cout << endl;
cout << endl;
answer = toupper(answer);
switch(answer)
{
case 'Y':
Entrynumber++;
cout << "began record number " << Entrynumber << "+ 1." << endl;
cout << "Enter the last name of the person to be entered" << endl;
cin >> stringentry;
cout << endl;
stringlength = stringentry.length();
strcpy(Record[Entrynumber].Last_Name, stringentry.c_str());
Record[Entrynumber].Last_Name[stringlength] = '*';
cout << "Enter the first name of the person" << endl;
cin >> stringentry;
cout << endl;
stringlength = stringentry.length();
strcpy(Record[Entrynumber].First_Name, stringentry.c_str());
Record[Entrynumber].First_Name[stringlength] = '*';
cout << "Enter the SSN of the person" << endl;
cin >> Record[Entrynumber].SSN;
cout << endl;
cout << "Enter the age of the person" << endl;
cin >> Record[Entrynumber].Age;
cout << endl;
cout << "Enter the address of the person" << endl;
cin.getline(Record[Entrynumber].Address,70);
cout << endl;
stringentry = Record[Entrynumber].Address;
stringlength = stringentry.length();
Record[Entrynumber].Address[stringlength] = '*';
cout << "you entered:" << endl;
for(jim = 0 ; Record[Entrynumber].Last_Name[jim + 1] != '*' ; jim++)
{
cout << Record[Entrynumber].Last_Name[jim];
}
cout << ',' ;
for(jim = 0 ; Record[Entrynumber].First_Name[jim + 1] != '*' ; jim++)
{
cout << Record[Entrynumber].First_Name[jim];
}
cout << endl;
cout << Record[Entrynumber].SSN << endl;
cout << Record[Entrynumber].Age << endl;
for(jim = 0 ; Record[Entrynumber].Address[jim + 1] != '*' ; jim++)
{
cout << Record[Entrynumber].Address[jim];
}
cout << endl;
cout << endl;
goto Answerinput;
case 'N':
cout << "ok" << endl;
break;
default:
cout << "invalid answer" << endl;
goto Answerinput;
}
输出到控制台

would you like to add another entry to the archive? (Y/N):
cin.getline() 和 getline() 都做同样的事情。
我正在使用 MVC++ 2008。
Record 数组中的所有字段都是结构体,Record[Entrynumber].Address 是一个 char 数组。
