Write a c++ program that prompts the user to enter integers, floats, and strings and displays the results of 'adding' them by calling an overloaded function called 'add'.

- main()

- prompt the user for 2 integers

- call the add() function

- display the result ( ie. 3 + 5 = 8 )

- prompt the user for 2 floats

- call the add() function

- display the result ( ie. 4.3 + 7.2 = 11.5 )

- prompt the user for 2 strings

- call the add() function

- display the result (concatenate) ( ie. "the" + "dog" = "thedog"

- overloaded add functions

- one function to handle integers, one for floats, one for strings

- use the '+' operator with the 2 arguments passed in as operands

Note: The '+' operator is a valid operator for two strings as operands. The

result is the concatenation of the two strings.
