when saving to file, words after white space are ignored

I've been working on saving to files and this was the result. The only problem is that anything after a space is ignored, (if you typed "john smith") it would print
("the last person to use this file was: john") I am using codeblocks with the GNU GCC compiler. Here is the code:

#include <iostream>
#include <cstdlib>
#include <fstream>

using namespace std;

int main()
string name;
ofstream saveData;
ifstream Data;
Data.open("Info.data", ios::binary);
Data >> name;
cout << "The last person to use the file was " << name << endl;
cout << "What is your name?" << endl;
cin >> name;
saveData.open("Info.data", ios::binary);
saveData << name;
cout << name << endl;
return 0;



For strings objects of ifstream (including cin) use input from beginning till the first space, and space is SPACE, TAB, and NELINE. So, you should use getline instead cin >>

Try this:

getline(Data, name);


cout << "What is your name?" << endl;
//cin >> name;
getline(cin, name);


By the way, in your code after

   Data.open("Info.data", ios::binary);

you use

   Data >> name;

So, stream opened in binary mode is read by >> - it is not so good.
