Which one is not the signatures of constructoroveraload? class of parameters Order of parameters No of parameters Types of parameters

To determine which option is not a signature of constructor overloading, let's briefly explain the concept of constructor overloading.

In object-oriented programming, constructor overloading allows a class to have more than one constructor with different parameter lists. The signature of a constructor is defined by the following attributes:

1. Class of Parameters: The type of the parameters defines part of the constructor's signature.

2. Order of Parameters: The arrangement of different parameter types matters as constructors must be distinguishable based on this order.

3. Number of Parameters: The total number of parameters is crucial since having a different count allows constructors to overload.

4. Types of Parameters: The specific types of the parameters help distinguish overloaded constructors.

Conclusion

Based on the explanations above, "Class of parameters" refers to the types, so it is relevant. "Order of parameters," "No of parameters," and "Types of parameters" are also significant.

Thus, the option that is not typically considered a distinct signature for constructor overloading is "Types of parameters" as it overlaps with the notion of class distinctions in parameter types. Therefore, the correct answer would be this option, though it might be subject to interpretation depending on contextual definitions in some programming languages.

Final Answer: Types of parameters is not distinctly representative of constructor overloading.
