Complex numbers program in c language | CTechnotips

Complex numbers definition

Complex numbers are two dimensional numbers i.e. it consists real part and imaginary part.

Complex numbers are written as a + ib

Where a and b are real numbers and i² = -1

Code 1:

1. How to use complex numbers in c

2. C language complex numbers

#include<stdio.h>

int main(){

int a,b;

printf("Enter any complex number in the format a+ib: ");

scanf("%d+i%d",&a,&b);

printf("Real part is: %d",a );

printf("\nImaginary part is: %d",b);

return 0;

}

Code 2:

1. C program to printf complex numbers

#include<stdio.h>

int main(){

int a,b;

printf("Enter the real part of complex number: ");

scanf("%d",&a);

printf("Enter the imaginary part of complex number: ");

scanf("%d",&b);

printf("\nComplex number is: %d%+di",a,b );

return 0;

}

Operation on complex numbers:

Addition of complex number

(a + ib) + (c + id) = (a+c) + i(b+d)

Subtraction of complex numbers

(a + ib) -(c + id) = (a+c) + i(b-d)

Multiplication of complex numbers

(a + ib) *(c + id) = (ac-bd) + i(bc+ad)

Divison of complex numbers

(a + ib) / c + id) = ((ac + bd) + i(bc-ad))/(c² + d²)
