C ++：按制表符拆分字符串，但包含空格

Question

I am working on a client/server program using sockets and I am trying to parse the input file. I have a struct to store the Majors, the early career pay, and the mid-career, respectively. The client program asks the user to input the name of the major and the server program returns both salaries.

The issue with the input file is this:

Geophysics 54100 122200

Cognitive Science 54000 121900

Electrical Power Engineering 68600 119100

They are all separated as Major[TAB]Pay[Tab]Pay, and the majors have spaces in them. I want to store each of them in the struct.

Any solution to this?

Answer 1

You can use the third argument in getline() to say what character to stop at. The default is \\n , but you can also specify that it is \\t to have it stop at the tab you want:

getline(std::cin, line, '\t');

Answer 2

Start with something this:

ifstream f("c:\\temp\\test.txt");
string s;
while (getline(f, s))
{
    istringstream iss(s);
    string major, early, mid;
    getline(iss, major, '\t');
    getline(iss, early, '\t');
    getline(iss, mid, '\t');
    cout << major << '|' 
         << early << '|' 
         << mid   << endl;
}
