Question

Show how to declare a tag namedcomplex for a structure with two members,real andimaginary, of type double.

Answer 1

#include <iostream>

using namespace std;

struct complex{ //Structure of name complex..

double real;//real part of type double..

double imaginary;//imaginary part of type double..

};

int main() {

complex n2; //object of structure complex..

n2.real=2.1;//assigining 2.1 to the real part..

n2.imaginary=5.6;//assigning 5.6 to the imaginary part..

cout<<n2.real<<" + "<<n2.imaginary<<"i"<<endl;//printing the complex number..

return 0;

}

Output:-

2.1 + 5.6i

Step-by-step explanation:

Declaring an object of structure complex name n2. Assigning 2.1 to the real part and 5.6 to the imaginary part.Then after that printing the output.
