Back To C++ Structures

nested structure means structure within a structure

//program to create a structure complex number with members(real and imaginary), creates two structure variables and passes these variables to function which calculates sum of two complex number structure variables into a new structure variable and returns the variable
#include<iostream.h>
#include<conio.h>

	int real;
	int imaginary;

    c.real=a.real+b.real;
    c.imaginary=a.imaginary+b.imaginary;
    return c;
