Write a function namedmake_complex that stores its twoarguments (both of type double) in acomplex structure, then returns thestructure.

#include <iostream>

using namespace std;

struct complex{//structure of comlex number..

double real;

double img;

};

complex make_complex(double a,double b)//function to return complex number with two arguments of type double..

{

   complex n1;

   n1.real=a;

   n1.img=b;

   return n1;//returning complex number..

}

int main() {

   complex n;

   double a,b;

   cout<<"Enter real and Imaginary respectively"<<endl;

   cin>>a>>b;//taking input of real and imaginary parts..

   n=make_complex(a,b);//calling function..

   cout<<"Comlex number is : "<<n.real<<" + i"<<n.img;//printing the output..

return 0;

}

output:-

Enter real and Imaginary respectively

5.4 8.9

Comlex number is : 5.4 + i8.9

Explanation:

First I have created a structure for complex number.Then created a function to make complex number according to the question which returns a complex number.
