C++ ifstream error

Heres my code:

using namespace std;                  // Global using directive
#include <iostream>                        // Header file for cout and endl
#include <iomanip>                        // Header file for I/O manipulators

int main()                                    // Start of main() function
{
string source;                              // variable for the input file
int numChar;                              // variable for number of characters

cout << "Enter the name of the source program file now: ";            //Prompt user
cin >> source;
cout << endl << endl;

//-------------------INPUT---------------------

ifstream inputfile (source);

//----------------------------------------------

return 0;                                    // Signal successful program execution

} // End of main()

Heres my errors:

"Program06.cpp", line 28: Error: The type "std::ifstream " is incomplete.
"Program06.cpp", line 28: Error: The type "std::ifstream " is incomplete.
2 Error(s) detected.

Was able to compile with VC++ 6.0

#include <iostream> // Header file for cout and endl
#include <iomanip> // Header file for I/O manipulators
#include <fstream>

using namespace std; // Global using directive

int main() // Start of main() function
{
char szsource[256] = {0}; // variable for the input file
int numChar; // variable for number of characters

cout << "Enter the name of the source program file now: "; //Prompt user
cin >> szsource;
cout << endl << endl;

string source = szsource;
//-------------------INPUT---------------------

ifstream inputfile;
inputfile.open(source.c_str());

//----------------------------------------------

return 0; // Signal successful program execution

} // End of main()

Thanks cookre, guess it just slipped my mind or I was in too big of a hurry.

That happens to all of us.
After 36 years programming, I still do it.
But as you gain experience, you immediately recognize the causes of more and more errors.
