Write a programe for complex number using C language

- September 03, 2022

So, Hello guys today i will shared you about how to create a programme for complex nimber using c programming;
So, Without any click bait Let's start
Here is the source code for Complex Number Coding:

#include <stdio.h>
#include <stdlib.h>
struct complex
{
double real, imag; //real and imag of type double
};
int main()
{
int choice, a, b, z;
struct complex x, y, c;
while(1)
{
printf("Enter your choice\n"); //choices for operations
printf("Press 1. Addition.\n");
printf("Press 2. Subtra tion\n");
printf("Press 3. Multiplication\n");
printf("Press 4. Division\n");
printf("Press 5. Exit\n");
scanf("%d", &choice);
if (choice == 5)
exit(0);
if (choice >= 1 && choice <= 4)
{
printf("Enter the value of x and y for first complex number:");
scanf("%lf%lf", &x.real,&x.imag);
printf("Enter the value of x and y for second complex number:");
scanf("%lf%lf", &y.real,&y.imag);
}
if (choice == 1) //addition
{
c.real = x.real + y.real;
c.imag = x.imag + y.imag;
if (c.imag >= 0)
printf("Sum of the complex numbers = %.2lf+%.2lfi", c.real, c.imag);
else
printf("Sum of the complex numbers = %.2lf %.2lfi", c.real, c.imag);
}
else if (choice == 2) //subtraction
{
c.real = x.real - y.real;
c.imag = x.imag - y.imag;
if (c.imag >= 0)
printf("Difference of the complex numbers = %.2lf+%.2lfi", c.real, c.imag);
else
printf("Difference of the complex numbers = %.2lf %.2lfi", c.real, c.imag);
}
else if (choice == 3) //multiplication
{
c.real = x.real*y.real - x.imag*y.imag;
c.imag = x.imag*y.real + x.real*y.imag;
if (c.imag >= 0)
printf("Multiplication of the complex numbers = %.2lf+%.2lfi", c.real, c.imag);
else
printf("Multiplication of the complex numbers = %.2lf %.2lfi", c.real, c.imag);
}
else if (choice == 4) //division
{
if (y.real == 0 && y.imag == 0)
printf("Division by 0 + 0i isn't allowed.");
else
{
a = x.real*y.real + x.imag*y.imag;
b = x.imag*y.real - x.real*y.imag;
z = y.real*y.real + y.imag*y.imag;
if (a%z == 0 && b%z == 0)
{
if (b/z >= 0)
printf("Division of the complex numbers = %.2lf+%.2lfi", a/z, b/z);
else
printf("Division of the complex numbers = %d %di", a/z, b/z);
}
else if (a%z == 0 && b%z != 0)
{
if (b/z >= 0)
printf("Division of two complex numbers = %.2lf+ %.2lf/%.2lfi", a/z, b, z);
else
printf("Division of two complex numbers = %.2lf%.2lf/%.2lfi", a/z, b, z);
}
else if (a%z != 0 && b%z == 0)
{
if (b/z >= 0)
printf("Division of two complex numbers = %.2lf/%.2lf+%.2lfi", a, z, b/z);
else
printf("Division of two complex numbers = %.2lf %.2lf/%.2lfi", a, z, b/z);
}
else
{
if (b/z >= 0)
printf("Division of two complex numbers = %.2lf/%.2lf + %.2lf/%.2lfi",a, z, b, z);
else
printf("Division of two complex numbers = %.2lf/%.2lf %.2lf/%.2lfi", a, z, b, z);
}
}
}
else
printf("Invalid choice.");
printf("\nPress any key to enter choice again...\n");
}
}
