Using getline(cin, s) after cin
I need the following program to take the entire line of user input and put it into string names:
cout << "Enter the number: ";
int number;
cin >> number;
cout << "Enter names: ";
string names;
getline(cin, names);
With the cin >> number command before the getline() command however (which I'm guessing is the issue), it won't allow me to input names. Why?
I heard something about a cin.clear() command, but I have no idea how this works or why this is even necessary.
Answer
cout << "Enter the number: ";
int number;
cin >> number;
cin.ignore(256, '\n'); // remaining input characters up to the next newline character
// are ignored
cout << "Enter names: ";
string names;
getline(cin, names);
