Simple C++ Substring Issue

Question

The program does not properly find the substrings of each section of the name "John Fitzgerald Kennedy", and cannot output each name on a separate line. The program outputs a out of range exception and does not even show the second name, only the first. How would I ouput each name on each separate line?

#include <iostream>
#include <string>

using namespace std;

int main()
{

string fullName="",
        firstName="",
        middleName="",
        lastName="";

cout<<"Enter your full name: ";
cin>>fullName;

firstName=fullName.substr(0,4);
middleName=fullName.substr(4,14);
lastName=fullName.substr(14,19);

cout<<firstName<<endl;
cout<<middleName<<endl;
cout<<lastName;

cin.get();
cin.get();

return 0;
}

Answer 1

cin>>fullName;

stops reading the standard input when it encounters the first space. What you need is a command like

getline(cin, fullName);

to read the entire line along with the spaces and then chunk them to get different parts of the name.
