Obj Parser

I followed a tutorial online on how to create a obj file parser, so far my parser reads a obj file and stores all the vertices into a struct named coordinate. Am not quite sure, how to use the coordinates in my struct in my main graphic pipeline

My parser:

void ObjParser(const char* szFileName)
{
    ifstream myfile; //use all the method of the ifstream
    std::vector<std::string*>coord;
    std::vector<coordinate*> vertex;
    myfile.open(szFileName);
    if(myfile.is_open())
    {
        //The file is open,use while loop to check file
        char buf[256]; //create buffer to read line
        while(!myfile.eof())//while we are not at the end of the file.
        {
            myfile.getline(buf,256);
            coord.push_back(new std::string(buf));
        }
        for(int i = 0; i <coord.size(); i++)
        {
            //check if it's a comment or not
             if(coord[i]->c_str()[0]=='#')
                 continue;
             else if(coord[i]->c_str()[0]=='v' && coord[i]->c_str()[1]==' ') 
             {
                 char tmp;
                 float tmp_x,tmp_y,tmp_z;
                 sscanf_s(coord[i]->c_str(),"v %f %f %f",&tmp_x,&tmp_y,&tmp_z); //read in the 3 
                 vertex.push_back(new coordinate(tmp_x,tmp_y,tmp_z)); //and then add it to the end of our vertex list
             }
        }
        //Delete coord to avoid memory leaks
        for(int i = 0; i < coord.size();i++)
        delete coord[i];
    }
    else{
        //Display error message, cause the file connot be opened
        MessageBox(NULL, "Error occured while opening file", NULL, NULL);
    }
    //once complete close file.
    myfile.close();
}

the structure of my coordinate class:

struct coordinate{
    float x,y,z;
    coordinate(float a, float b,float c) : x(a),y(B)/>/>,z(c) {};
};

I wanna be able to use it in my geometry pipeline and create a wireframe of it.
for example at the moment my vertices are had coded like this:

void wireframe(HDC hdc){
    //vertices coordinates:
    const int verticescount = 8;
    Vertex vertices[verticescount] = {Vertex(-5.0f, -5.0f, 5.0f, 1.0f), 
                                      Vertex(5.0f, -5.0f, 5.0f, 1.0f),
                                      Vertex(5.0f, 5.0f, 5.0f, 1.0f),
                                      Vertex(-5.0f, 5.0f, 5.0f, 1.0f),
                                      Vertex(-5.0f, -5.0f, -5.0f, 1.0f),
                                      Vertex(5.0f, -5.0f, -5.0f, 1.0f),
                                      Vertex(5.0f, 5.0f, -5.0f, 1.0f),
                                      Vertex(-5.0f, 5.0f, -5.0f, 1.0f)};
}

any help appreciated on how to get it working.
