Write a C program that uses functions to perform the different operations.

Write a C program that uses functions to perform the following operations:

i. Reading a complex number

ii. Writing a complex number

iii. Addition and subtraction of two complex numbers

iv. Multiplication of two complex numbers. Note: represent complex number using a structure.

Program Code:

#include<stdio.h>

#include<string.h>

struct complex1

{

int r;

inti;

}c1,c2,c3;

void add(struct complex1 c1,struct complex1 c2);

void sub(struct complex1 c1,struct complex1 c2);

void multi(struct complex1 c1,struct complex1 c2);

void main()

{

printf("\n enter first complex no: ");

scanf("%d%d",&c1.r,&c1.i);

printf("\n enter second complex no: ");

scanf("%d%d",&c2.r,&c2.i);

printf("\n enter first complex no:%d+i%d",c1.r,c1.i);

printf("\n enter second complex no:%d+i%d",c2.r,c2.i);

add(c1,c2);

sub(c1,c2);

multi(c1,c2);

}

void add(struct complex1 c1,struct complex1 c2)

{

c3.r=c1.r+c2.r;

c3.i=c1.i+c2.i;

printf("\n addition of two complex numbers is %d+i%d",c3.r,c3.i);

}

void sub(struct complex1 c1,struct complex1 c2)

{

c3.r=c1.r-c2.r;

c3.i=c1.i-c2.i;

printf("\n subtraction of two complex numbers is %d+i%d",c3.r,c3.i);

}

void multi(struct complex1 c1,struct complex1 c2)

{

c3.r=(c1.r*c2.r)-(c1.i*c2.i);

c3.i=(c1.r*c2.i)+(c1.i*c2.r);

printf("\n multiplication of two complex numbers is %d+i%d",c3.r,c3.i);

}
