a. Write a C program that reads a fraction ( Z 1 / Z 2 ) and return Z . Note that Z 1 , Z 2 , and Z are complex numbers whose real and imaginary parts are real numbers. Must use structures and functions to get credit. b. Test your code with Z 1 = 1 + 0 i and Z 2 = 1 1 i . The answer should be Z = 0.5 + 0.5 i.
