Problem with ofstream when defining member functions in source file

bobsta (10)
Hi,

I am having difficulties compiling my code. I recently cleaned up my code by dividing class declarations into an appropriate classname.h file and the definitions of constructors and member functions in a classname.cpp file (using a static library). The problem arises with the ofstream object which I use to write out my data. Below is my Beam.h file (The paths specified for the other include files are correct)

Here is the Beam.cpp file

					}



				}
				if (test>0){
						std::cout << "\nError writing MU profile!\n";
				}
				fout.close();
}



The ellipsis on line 7 are only there to indicate that the other constructor(s)/destructor and member functions are declared in the intervening space (but I don't think these are relevant to the problem)

My error messages are as follows:

Beam.cpp: In member function ‘void Beam::writeMUProfile(char*)’:
Beam.cpp:14: error: ‘ofstream’ was not declared in this scope
Beam.cpp:14: error: expected `;' before ‘fout’
Beam.cpp:15: error: ‘fout’ was not declared in this scope

I would really appreciate some help with this.
