How to add two complex numbers by passing structure to a function in C language?
In order to add two complex numbers in C programming language, the user has to take two complex numbers as structure members and perform addition operation on those two numbers by creating a user-defined function.
Algorithm
Refer an algorithm given below for addition of two complex numbers.
Step 1: Declare struct complex with data members. Step 2: Declare name for structure and variables. Step 3: Enter real and imaginary part for first complex number at run time. Step 4: Enter real and imaginary part for second complex number at runtime Step 5: Compute addition of number1 and number2 by calling function. Go to step 7. Step 6: Print the result. Step 7: Compute addition
- Declare temp variable
- temp.real = num1.real + num2.real;
- temp.imag = num1.imag + num2.imag;
- return (temp);
Example
Following is the C program for adding two complex numbers by passing structure to a function −
#include <stdio.h>
typedef struct complex{
float real;
float imag;
} complex;
complex addition(complex num1, complex num2);
int main(){
complex num1, num2, value;
printf("entering real and imag parts of first complex no:
");
scanf("%f %f", &num1.real, &num1.imag);
printf("entering real and imag parts of second complex no:
");
scanf("%f %f", &num2.real, &num2.imag);
value= addition(num1, num2);
printf("result = %.1f + %.1fi", value.real, value.imag);
return 0;
}
complex addition(complex num1, complex num2){
complex temp;
temp.real = num1.real + num2.real;
temp.imag = num1.imag + num2.imag;
return (temp);
}Output
When the above program is executed, it produces the following result −
entering real and imag parts of first complex no: entering real and imag parts of second complex no: result = 0.0 + 0.0i
