You wish to convert a container class to a template container class. Which of the following should you consider?
select all that apply
| A. |
Make sure operations on container data are not type specific. For example, don't use string functions on container data. |
| B. |
Make implementation visible. One way to do this is to include both interface and implementation in the header file. |
| C. |
Make sure all return statements that return container data only return container data. If a return statement returns container data under certain conditions, but another return statement returns something that is not container data under other conditions, there could be a data type conflict when a different data type is used for this template. |
| D. |
Make the class visible to the client. One way to do this is to include the main function in the header file. |
