Working with Multiple Typenames in Templates

Sometimes you will need more than one type to use in the function, and for this you can simply add more template parameters. Just make sure you give them different names.

Note

There is no inherent limit to the number of template parameters. However, as a general guideline keep the number of them as low as possible.

Create the function template print_pair that allows you to output a formatted message containing a pair of values. By defining the template parameters, you can specify the types of the two values you want to print.

Task

Create and call a template with multiple type parameters.

  1. Fill in the ___ to complete the template definition.
  2. Call the template twice:
    • First call: Use <int, std::string> as the template types.
    • Second call: Use <char, float> as the template types.
