/*Ava N.*/
//This program implements complex numbers as a structure and allows a user to perform calculations with them. The structure contains real and imaginary portions of a complex number. The functions add, subtract, multiply, divide and display complex numbers. I have allowed the user to select what functions they want to use (much like my calculator.c programs from last week) and enter the complex numbers they want to perform calculations with.

#include <stdio.h>
#include <math.h>

typedef struct {
	int real; //real
	int imag; //imaginary
} complx;

   complx s; //second number
   complx a; //answer
   complx o; //operation
