foo not writing whole var

hello,
Im working on a little test program where the user can input reminder notes in a simple little program then load them later.
This is just a part of the code

PHP Code:


		
			
 cout << "Date:";

    cin >> date;

    cout << "Note: \n";

    cin >> note;

    ofstream foo("datebase.txt");

    foo << "Date:" << date << "\n";

    foo << "Note:" << note;

}

Now the output comes out right exept for the note part is only writing the first word or group of text???

Second what kinda file should i be saving to and how would i load the text?

thanks for yor time,
jordan

"Now the output comes out right exept for the note part is only writing the first word or group of text???"

Actually it's cin>>note that is only reading the first word, and that's because the >> operator is defined to stop reading as soon as it encounters whitespace(spaces, tabs, or newlines).

For string types:
string text;
getline(cin, text);

For char arrays:
char text[100];
cin.getline(text, 100);

"Second what kinda file should i be saving to and how would i load the text?"

Writing to a text file is fine. If by "load" you mean "read from the file"

Code:

ifstream inFile("database.txt");
string text;

while(!inFile.eof())
{ 
   getline(inFile, text);
   cout<<text<<endl;
}

using namespace std;

getline(cin, text);

Code:

#include<iostream> //cout, cin defined in there
#include<string> //string types defined in there
#include <fstream> //ofstream, ifstream defined in there

using namespace std;
//need this otherwise you would have to refer to cout with
//its full name std::cout, same with everything else in the
//standard library.  Read about "namespaces" for more 
//information

int main()
{ 
	ofstream outFile("C:\\TestData\\output.txt");
	string text;

	for(int i=0; i<3; i++)
	{
		cout<<"Enter a message:"<<endl;	
		getline(cin, text);
		//Reads from the keyboard until a \n is encountered
		//which occurs when the user hits return.
		
		outFile<<text<<endl;
	}
	
	ifstream inFile("C:\\TestData\\output.txt");
	
	cout<<endl<<"Here are the messages:\n";
	while(!inFile.eof()) // while not at the end-of-file
	{

		getline(inFile, text);
		cout<<text<<endl;
	}

	return 0;
}

Get the book: "Ivor Horton's Beginning C++" and you can look up stuff you don't know how to do, or don't understand.
