Splitting String Help

[jeffery30162]

Hi, I have this string here:


"
Membership information
----------------------
Nodeid Votes Name
1 1 Server1
2 1 Server2 (local)

"
How can I read it line by line and store the node ids and names in an array?

What do you have in your program now? What have you gotten so far?

Use a string string to read your string, if you have carriage returns/end-of-line characters ('\n') delimiting each line. Instead of using std::cin, use a std::istringstream as your input source.

I do not know if there are any \n to skip lines because I am using sshpass to ssh into a linux machine to run a command and retrieve the output as a string

[E0p9LyTq]

If there are typical input delimiters that would cause std::cin to retrieve partial input from the stream, such as spaces, then a string stream will work the same way. A stream in C++ is a stream no matter where it comes from. The key thing is knowing the exact nature of the data string you are trying to muck with.

Try :

int id1, id2;
std::string server_name;
std::stringstream ss ("1 1 Server1\n" "2 1 Server2");

cout << "Output : " << endl;
while(ss >> id1 >> id2 >> server_name)
{
    cout << "id1 == " << id1 << endl;
    cout << "id2 == " << id2 << endl;
    cout << "server name == " << server_name << endl;
}
