function do_upload() {     $this->load->model("gids_model",'',true);     $config['upload_path'] = './uploads/';     $config['allowed_types'] = 'gif|jpg|png';     $config['max_size'] = '1000';     $config['file_name'] = 'profile_picture'.$_session['id'].'.jpg';     $config['overwrite'] = 'true';      $this->load->library('upload', $config);      if ( ! $this->upload->do_upload())     {         $error_upload = array('error' => $this->upload->display_errors());         redirect('gids/datum', $error_upload);     }     else     {         $this->gids_model->update_profile($this->input->post('student_id'), $this->input->post('voornaam'), $this->input->post('naam'), $this->input->post('email'), $this->input->post('wachtwoord'), $this->input->post('opleiding'), $this->input->post('school'), $this->input->post('over'), $this->input->post('image'), $this->input->post('gebruikersnaam'));         //$e = $this->input->post('student_id');          $data_upload = array('upload_data' => $this->upload->data());         redirect('gids/datum', $data_upload);     } }

and model:

public function update_profile($id, $voornaam, $naam, $email, $wachtwoord, $opleiding, $school, $over, $image, $gebruikersnaam){           $data = array(                 'student_id' => $id,                 'voornaam' => $voornaam,                 'naam' => $naam,                 'email' => $email,                 'wachtwoord' => $wachtwoord,                 'opleiding' => $opleiding,                 'school' => $school,                 'over' => $over,                 'image' => $image,                 'gebruikersnaam' => $gebruikersnaam           );          $this->db->where('student_id',  $id);          $this->db->update('tbl_student', $data); }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
