dynamic query

The below code gives me output with C_01 to C_10 as shown below, I want to dynamically add c_11,c_12...c_xx (xx any number max value as 99)

If we do "select * from #cond"  for mid col value 1 we have 10 distinct c_id values hence we have c_01 to c_10 columns below(which is max 10 records for mid 1, and for mid 2 we have only 4 rec 10,11,12 and 13) means we have picked up max value of cid for any mid value and created those many columns.   

Now to this I want to pickup the max cid which is c_10 in this case and add few more columns c_xx to the #res table with out adding any more records to #cond table, so that my #res table has c_11, c_12....c_xx number of columns. (i,e more number of columns for future use)

the image output is from #res output table
