The string Class Input

Another useful thing to know about a class is what input options are available. For C-style strings, recall, you have three options:

char info[100];cin >> info;             // read a wordcin.getline(info, 100);  // read a line, discard \ncin.get(info, 100);      // read a line, leave \n in queue

cin.getline(info,100,':');    // read up to :, discard :getline(stuff, ':');          // read up to :, discard :

The main operational difference is that the string ...
