C Program to Add Two Complex Numbers by Passing Structure to a Function

Add Two Complex Numbers

Output

For 1st complex number
Enter the real and imaginary parts: 2.1
-2.3

For 2nd complex number
Enter the real and imaginary parts: 5.6
23.2
Sum = 7.7 + 20.9i

In this program, a structure named complex is declared. It has two members: real and imag. We then created two variables n1 and n2 from this structure.

These two structure variables are passed to the add() function. The function computes the sum and returns the structure containing the sum.

Finally, the sum of complex numbers is printed from the main() function.
