15th Week OJ Brush problem--problem n:c++ exercises plural class--overloaded operator

Description

Write a program that handles the addition of a complex number to a double, and the result is stored in a double variable d1, outputting the value of D1, and then outputting the value in plural form. Define the complex (plural) class that contains the overloaded type conversion operator in the member function:
Operator double () {return real;}

Input

A plural with a double number

Output

The value of D1 and the plural form of this value

Sample Input

3 42.5

Sample Output

D1=5.50c2= (5.50, 0.00)

Learning experience: This problem is still relatively good to write, but is the output of the format to pay attention to, the format is a big problem, continue to work, and recently are their own in the settlement of the problem, so very good, continue to work!!!
