c++ - Error: Use of class template requires template argument list -

When I try to run my program, this error "C2955 error:" Fourth "shows: Class templates Use template logic is required for the list "

  #include & lt; Iostream & gt; using namespace std; Template & lt; Square t, int n & gt; Class IV {Private: TA [N]; Public: Zero ReadData (); Zero performance data (); }; Around :: Zero: ReadData () {for (int i = 0; i & lt; n; ++ i) cin & gt; One. [I]; } Zero four :: performance data (for (int i = 0; i   
 Do I have a template To type again?   
 
 
 The members of the template class itself are the owner of the template class. When such a member is defined outside of his or her class, then it should be clearly declared as a template.  
 So you need a change.  
  minus four :: ReadData ()   
 to  
  template  n>: ReadData ()   
 and  DisplayData  function.  
 and some other errors are:  
  ReadData , change  
  cin> in the function & Gt; A. [I];   
 to  
  cin> & Gt; A [i];   
 and  DisplayData ,  
  cin & gt; & Gt; A. [I] & lt; & Lt; '\ T';   
 to  
  cout & lt; & Lt; A [i] & lt; & Lt; '\ T';
