Question

I need to read in a string and then an integer until the user indicates end of input (ctrl-d in linux). Again, I am stuck. Currently I have a while loop:

while (getline(cin, line))

However, that gives an entire line and then I cannot seem to separate the string from the integer. Suggestions would be most appreciated! 🙂

Answer 1

If the string and the integer is separated by whitespace;
Do this:

while(std::cin>>your_string>>your_num>>std::ws){}

You can choose your own delimiter, by writing a manipulator yourself.

Another approach would be to do it your way, and put the input line into a stringstream and extract the string and numbers from it. That approach seems roundabout to me as you get strings from a stream only to put it into another stream.
