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 )
