Hey! Have you learnt looping in the CS course?

 int c_i=0;
 int cc_len = m_splitString.GetLength ();
 if (c_i +4 <= cc_len)
 {
  cc1=m_splitString.Mid (c_i,4);
  c_i = c_i + 4;
 }
 if (c_i +4 <= cc_len)
 {
  cc2=m_splitString.Mid (c_i,4);
  c_i = c_i + 4;
 }
 if (c_i +4 <= cc_len)
 {
  cc3=m_splitString.Mid (c_i,4);
  c_i = c_i + 4;
 }

 if (c_i +4 <= cc_len)
 {
  cc4=m_splitString.Mid (c_i,4);
  c_i = c_i + 4;
 }
 if (c_i +4 <= cc_len)
 {
  cc5=m_splitString.Mid (c_i,4);
  c_i = c_i + 4;
 }
 if (c_i +4 <= cc_len)
 {
  cc6=m_splitString.Mid (c_i,4);
  c_i = c_i + 4;
 }
