What does this SWITCH error mean?

Question

I'm getting this error for my CASE 5/6/7/8.

I'm sure it's something obvious as it was working before I started adding addition function calls to CASE 4.

What does the error mean?

error: case label in scope of identifier with variably modified type not containing enclosing switch statement

 switch(menu_selection())
    {
        case 0 :    i = find_empty_record(data_record);       //New record
                    if (i!=-99)
                    {
                        printf("\n\nRecord #%d found to be empty...\n\n",i);
                        data_entry(&data_record[i],i,&array_flag);

        default :

Answer 1

student_record data_record[rec_cnt];

You can't declare stuff inside a switch.

• Do it before the switch

• Do it in a block:

  case 4:
  {
      student_record data_record[rec_cnt];
      /* ... */
  }
  

Answer 2

In case 4 you have an array declaration: student_record data_record[rec_cnt];

Create an extra block:

case 4:   
  {
    rec_cnt = get_text_file_size(import_file_name); //Import Text File
    student_record data_record[rec_cnt];
    import_text_file(data_record,import_file_name,array_flag,rec_cnt);
  }
  break;
