Add Complex Numbers by Passing Structure

Complex number addition

Complex numbers have real and imaginary parts. A structure is perfect for grouping these two values.

Program Code

struct_complex.c

1#include <stdio.h>

3struct Complex {
4    float real;
5    float imag;
6};

8struct Complex addComplex(struct Complex c1, struct Complex c2) {
9    struct Complex result;
10    result.real = c1.real + c2.real;
11    result.imag = c1.imag + c2.imag;
12    return result;
13}

15int main() {
16    struct Complex num1 = {3.5, 2.5};
17    struct Complex num2 = {1.5, 4.5};
18    
19    struct Complex sum = addComplex(num1, num2);
20    
21    printf("First:  %.1f + %.1fi\n", num1.real, num1.imag);
22    printf("Second: %.1f + %.1fi\n", num2.real, num2.imag);
23    printf("Sum:    %.1f + %.1fi\n", sum.real, sum.imag);
