#Define a function which takes TWO objects representing complex numbers and returns new complex 
#number with a addition of two complex numbers. Define a suitable class ‘Complex’ to represent the 
#complex number. Develop a program to read N (N >=2) complex numbers and to compute the addition 
#of N complex numbers.
