Introduction
Write a C program that uses functions to perform the following operations:i) Reading a complex number
ii) Writing a complex number
iii) Addition of two complex numbers
iv) Multiplication of two complex numbers
(Note: represent complex number using a structure.)
#include<stdio.h> #include<math.h> void arithmetic(int opern); struct comp { double realpart; double imgpart; }; void main() { int opern; printf("\n\n \t\t\t***** MAIN MENU *****"); printf("\n\n Select your option: \n 1 : ADD\n 2 : MULTIPLY\n 0 : EXIT \n\n\t\t Enter your Option [ ]\b\b"); scanf("%d",&opern); switch(opern) { case 0: exit(0); case 1: case 2: arithmetic(opern); default: main(); } } void arithmetic(int opern) { struct comp w1, w2, w; printf("\n Enter two Complex Numbers (x+iy):\n Real Part of First Number:"); scanf("%lf",&w1.realpart); printf("\n Imaginary Part of First Number:"); scanf("%lf",&w1.imgpart); printf("\n Real Part of Second Number:"); scanf("%lf",&w2.realpart); printf("\n Imaginary Part of Second Number:"); scanf("%lf",&w2.imgpart); switch(opern) { /*addition of complex number*/ case 1: w.realpart = w1.realpart+w2.realpart; w.imgpart = w1.imgpart+w2.imgpart; break; /*multiplication of complex number*/ case 2: w.realpart=(w1.realpart*w2.realpart)-(w1.imgpart*w2.imgpart); w.imgpart=(w1.realpart*w2.imgpart)+(w1.imgpart*w2.realpart); break; } if (w.imgpart>0) printf("\n Answer = %lf+%lfi",w.realpart,w.imgpart); else printf("\n Answer = %lf%lfi",w.realpart,w.imgpart); getch(); main(); }
