This program takes two distances in inch-feet system and stores in data members of two structure variables. Then, this program calculates the sum of two distances by passing it to a function and result is displayed in main() function.

Source Code to Add Two Complex Number

#include <stdio.h>
typedef struct complex{
    float real;
    float imag;
}complex;
complex add(complex n1,complex n2);
int main(){
    complex n1,n2,temp;
    printf("For 1st complex number \n");
    printf("Enter real and imaginary respectively:\n");
    scanf("%f%f",&n1.real,&n1.imag);
    printf("\nFor 2nd complex number \n");
    printf("Enter real and imaginary respectively:\n");
    scanf("%f%f",&n2.real,&n2.imag);
    temp=add(n1,n2);
    printf("Sum=%.1f+%.1fi",temp.real,temp.imag);
    return 0;
}
complex add(complex n1,complex n2){
      complex temp;
      temp.real=n1.real+n2.real;
      temp.imag=n1.imag+n2.imag;
      return(temp);
}

Output

For 1st complex number
Enter real and imaginary respectively: 2.3
4.5

For 1st complex number
Enter real and imaginary respectively: 3.4
5
Sum=5.7+9.5i

 

 
 In this program structures n1 and n2 are passed as an argument of function add(). This function computes the sum and returns the structure variable temp to the main() function.
