Complex number

#include<iostream.h>

class complex
{
                float real;
                float imag;
   public:
                void getnum();
                void putnum();
                void sum(complex,complex);

                cout<<real;
                if(imag<0)
                                cout<<imag<<"i\n";
                else
                                cout<<"+"<<imag<<"i\n";

                real=a.real+b.real;
                imag=a.imag+b.imag;

{
                real=a.real-b.real;
                imag=a.imag-b.imag;
}
int main()
{
                complex c1,c2,c3,c4;
                cout<<"\nEnter first complex number\n";
                c1.getnum();
                cout<<"\nEnter second complex number\n";
                c2.getnum();
                //Sum of two inputted numbers
                c3.sum(c1,c2);
                cout<<"\nThe Sum is : ";
                c3.putnum();
                //Difference of two inputted numbers
                c4.dif(c1,c2);
                cout<<"\nThe Difference is : ";
                c4.putnum();


Output:
Enter first complex number
Enter the real part : 4
Enter the imaginary part : 5
Enter second complex number
Enter the real part : 3
Enter the imaginary part : 6
The Sum is : 7+11i
The Difference is : 1-1i
