Opengl tga texture

I am trying to load a tga texture in opengl. I have an example that I am using but the problem I have with it is that it fails to load the file. I have added the tga file in the resource files folder and the code is below. When I say fail to load I mean it outputs it to the screen using this code

cout << "Error opening file" << endl;

not that there is a code error.

#include <iostream>
#include <fstream>
#include <stdio.h>
#include <windows.h>	   // Standard header for MS Windows applications
#include <GL/gl.h>		   // Open Graphics Library (OpenGL) header
#include <GL/glut.h>	   // The GL Utility Toolkit (GLUT) Header
 
#define KEY_ESCAPE 27
#define g_rotation_speed 0.2
float g_rotation;
 
 
using namespace std;
