    c1.input();

📘 Explanation:

This program demonstrates operator overloading in C++. The - operator is overloaded to subtract two complex numbers.

• Constructors: Default and parameterized constructors are used.
• operator-() subtracts the real and imaginary parts of two complex numbers.
• display() prints the result in the standard complex number format.

🧾 Sample Output:

Enter first part:
Enter real part:
5
Enter imag part:
3
Enter second part:
Enter real part:
2
Enter imag part:
1
Result after subtraction:
3-2i
