I'm trying to read some input from a file and print it. I have three files: Main.cpp Sudoku.cpp Sudoku.h.

For some reason the program will not print anything unless it's in the main function. If I print anything in one of the functions of Sudoku.cpp file and the use that function in the program, it will not print.

EDIT: I figured out the problem is in the "Load" function. Can anyone tell me what I did wrong there? It seems to freeze once it reaches that.

Main.cpp:

#include "stdafx.h"

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	cout << "hello" << endl; //"hello" actually prints; nothing else does
	Sudoku MyPuzzle;

	MyPuzzle.Load();
	MyPuzzle.Print();

	return 0;
}

Sudoku.h

#ifndef SUDOKU_H
#define SUDOKU_H
#include "StdAfx.h"

class Sudoku
{
public:
   void Load();
   void Print();
private:
  int Puzzle[9][9];
};
#endif

Sudoku.cpp

#include "stdafx.h"

using namespace std;

void Sudoku::Load() { //something wrong here
	ifstream fp_in("Project4_input1.in", ios::in);
	for(int i=0; i<9; i++){
		for(int j=0; j<9; j++){
			cin >> Puzzle[i][j];
		}
	}
	cout << "Loaded all values."<< endl;
	fp_in.close();
}

void Sudoku::Print() {
	for(int i=0; i<9; i++){
		for(int j=0; j<9; j++){
			cout << Puzzle[i][j] << " ";
		}
		cout << endl;
	}	
}

So when I compile the headers, build the project and run Main.exe I just get "hello". Nothing else is being written.

Maybe this is just something really simple that I'm not seeing.

Any help is greatly appreciated

Thank you

Well, you open a file to read, then you read the data from the keyboard -- that's what cin does.
