感谢您阅读这个问题。
基本上我正在尝试做一个可以实现以下目标的代码:
用户将看到这样的详细信息列表
终端视图:
Please select the department you want to add participant:
1. Admin
2. HR
3. Normal
4. Back to Main Menu
Selection: 3
normal's Department
UserID: 85 [ Name: Andrew, Department: normal ]
UserID: 86 [ Name: Jacky, Department: normal ]
UserID: 90 [ Name: Baoky, Department: normal ]
Current Selected Participant :
Usage:
Type exit to return to main menu
Type remove userid to remove participant
Type add userid to add participant
Selection:
问题是:我希望能够让用户添加任意数量的参与者,直到他决定“退出”到主菜单,但是我如何将它存储在字符串参与者中。
如何检测用户输入是“删除用户标识”或“添加用户标识”,然后获取用户标识
例如加 86 然后他加 90
然后他决定删除90
字符串如何跟上它
下面是我的代码:
do
{
cout << "Current Selected Participant : " << participant << endl;
cout << "" << endl;
do
{
if(counter>0)
{
//so it wont print twice
cout << "Usage: " << endl;
cout << "Type exit to return to main menu" << endl;
cout << "Type remove userid to remove participant" << endl;
cout << "Type add userid to add participant" << endl;
cout << "" << endl;
cout << "Selection: ";
}
getline(cin,buffer);
counter++;
}while(buffer=="");
if(buffer.find("remove"))
{
str2 = "remove ";
buffer.replace(buffer.find(str2),str2.length(),"");
if(participant.find(buffer))
{
//see if buffer is in participant list
buffer = buffer + ",";
participant.replace(participant.find(buffer),buffer.length(),"");
}
else
{
cout << "There no participant " << buffer << " in the list " << endl;
}
}//buffer find remove keyword
if(buffer=="exit")
{
done=true;
}
else
{
sendToServer = "check_account#"+buffer;
write (clientFd, sendToServer.c_str(), strlen (sendToServer.c_str()) + 1);
//see if server return found or not found
readFromServer = readServer (clientFd);
if(readFromServer=="found")
{
//add to participant list
participant += buffer;
participant += ",";
}
}//end if not exit
}while(done!=true);
一些用户建议我存储在字符串集中,如何存储在字符串集中,以及如何使终端能够识别选择中的“删除”和“添加”等关键字
然后获取由空格分隔的用户ID。
接下来是如果我存储在字符串集中如何删除以及如何将新值推入。
