17th Week OJ Brush problem--problem A: Implementing the Add operator overload in a complex class "C + + operator overloading"

Description

int home has i1 and I2 brothers, small hand a pull i1+i2, add up, double home has D1 and D2 sisters, small hand also pull, d1+d2, also added up. C + + village came the plural (Complex) family, there are two brothers C1 and C2, want to come up with a cumulative, stupid, C1.add (C2). C1 and C2 sad very much, also imagine other children like, small hand a pull, c1+c2, also can add up. This task is given to the magician who is looking at the problem, to help them a busy, so that the plural can also be added with the + number. (You can copy the code of the hint section to start your programming)

Input

Four numbers representing the real and imaginary parts of two imaginary C1 and C2 respectively. If input 2.5 3.1-4.5 0.3, represents two imaginary numbers: C1 (2.5+3.1i), C2 ( -4.5+0.3i)

Output

Result of two imaginary numbers added, format (a,bi) Form

Sample Input

2.5 3.1-4.5 0.3

Sample Output

( -2,3.4i)

Experience: This problem is very typical and very simple, there is a question to emphasize, the default constructor is generally written or relatively good, write member functions, Ken can define an object that does not require parameters, then you need to use the default constructor. So in order to avoid mistakes, or write insurance. Keep working on it!!!
