would suggest you to read CURSORS chapter of pl/sql programming.
1)open c_category
this stmt will open pre declared cursor
2) loop
this is loop stmt
3) fetch c_catergory into var_car_id, var catergory;
3rd stmt fetch values into local variables from opened cursor
4)exit when (c_categrory%not found);
this stmt tells pl/sql ,exit loop when it reaches last record
