我的学校项目有问题。我正在学校服务器上使用 UNIX 中的 VIM 编写它。当我在我的项目中插入记录时，姓氏被跳过。名字和姓氏同时提示，无需等待姓氏接收输入。见下文：
我的菜单是这样做的：
MENU
(I)nsert 新记录
(L)ast name search
(S)ave database to a file
(R)ead database from a file
(Q)uit输入选项：我
选择插入新记录
请输入员工的姓氏： 请输入员工的名字：
它在姓氏之前跳过！
我需要在某处添加 cout.flush() 吗？当我在姓氏部分下添加 cout.flush() 时，我收到此错误：
unixapps1:Lab1> make
g++ -o LSL lab1.cpp Employee.cpp
lab1.cpp: In function âEmployee createRecord()â:
lab1.cpp:41: error: âstruct std::istreamâ has no member named âflushâ
我的菜单代码是这样的：
int main() {
cout << "\n"
<< "************************************************************\n"
<< "Remember: Search for TODO's in VI before submitting project!\n"
<< "************************************************************\n\n";
char menu_choice;
string fileName;
// Create a database
LinkedSortedList<Employee> database;
while (true) {
// Display menu
cout << "MENU\n"
<< "(I)nsert new record\n"
<< "(L)ast name search\n"
<< "(S)ave database to a file\n"
<< "(R)ead database from a file\n"
<< "(Q)uit\n\n";
cout << "Enter choice: ";
cin >> menu_choice;
cout << endl;
switch (toupper(menu_choice)) {
case 'I':
cout << "Insert new record selected\n\n";
{database.insert(createRecord());}
break;
case 'L':
cout << "Last name search selected\n\n";
// TODO call function to search by last name
// TODO call search for Last Name
// TODO Print all matches found
{string searchVal = "";
database.find(searchVal);}
break;
case 'S':
cout << "Save database to a file selected\n\n";
// TODO call function to save database to file
// File I/O Save to file
cout << "Please enter a file name: " << endl;
cin >> fileName;
{char* file = (char*) fileName.c_str();
writeFile(file, database);}
break;
case 'R':
cout << "Read database from a file selected\n\n";
// TODOOA call function to read database from file
// File I/O Read file
cout << "Please enter a file name: " << endl;
cin >> fileName;
{char* file = (char*) fileName.c_str();
readFile(file, database);}
break;
case 'Q':
exit(EXIT_SUCCESS);
// default case:
default:
cout << "Invalid choice!\n\n"
<< "##### Please try again #####\n\n";
break;
cin >> menu_choice;
}
}
return 0;
}
这是我的createRecord()功能：
// Create the record to be inserted into the employee database
Employee createRecord() {
// Temporary variables for getting input from user
string stringInput = "";
int intInput = 0;
Employee newEmployee;
cout << "Please enter employee's Last Name: " << endl;
getline(cin, stringInput);
newEmployee.setLastName(stringInput);
cout << "Please enter employee's First Name: " << endl;
getline(cin, stringInput);
newEmployee.setFirstName(stringInput);
cout << "Please enter employee's ID: ";
getline(cin, stringInput);
stringstream myStream(stringInput);
myStream >> intInput;
newEmployee.setId(intInput);
cout << "Please enter employee's Salary: ";
getline(cin, stringInput);
myStream >> intInput;
newEmployee.setSalary(intInput);
cout << "Please enter employee's Department: ";
getline(cin, stringInput);
newEmployee.setDepartment(stringInput);
cout << "Please enter employee's Phone Number: ";
getline(cin, stringInput);
newEmployee.setPhoneNumber(stringInput);
cout << "Please enter employee's Address: ";
getline(cin, stringInput);
newEmployee.setAddress(stringInput);
cout << "Please enter employee's Hire Date: ";
getline(cin, stringInput);
newEmployee.setHireDate(stringInput);
}
