Give the function definition for the function with the following function declaration. Embed your definition in a suitable test program.

void  get_double(c/oub7e& i nput_number) ; //Postcondition: input_nuinber is given a value //that the user approves of.

You can assume that the user types in the input in normal everyday notation, such as 23.789, and does not use e-notation to type in the number. Model your definition after the definition of the function get_int given in Display 8.3 so that your function reads the input as characters, edits the string of characters, and converts the resulting string to a number of type double. You will need to define a function like read_and_clean that is more sophisticated than the one in Display 8.2, since it must cope with the decimal point. This is a fairly easy project. For a more difficult project, allow the user to enter the number in either the normal everyday notation, as discussed above, or in e-notation. Your function should decide whether or not the input is in e-notation by reading the input, not by asking the user whether she or he will use e-notation
