1. Select the derived class method definitions that represent actual method chai

Question

1.

Select the derived class method definitions that represent actual method chaining (never mind the reason or effect, as long as it demonstrates a derived class method chaining to a base class method). There is more than one correct answer.

2.. Consider the following code fragment (assumed to be in an otherwise correct program):

Assume there are no omitted statements within this fragment -- you see everything. Check the true statements (may be more than one):

Illegally attempts to delete non-dynamic memory.

  string SubClass::toString(string msg)  {     return BaseClass::toString(msg) + " hi dad.";  }  

  string SubClass::toString()  {     return BaseClass::toString("My Message ----") + " hi dad.";  }  

  void SubClass::methodTwo(int a)   {     BaseClass::methodTwo(4); // calling int-parameter method     // other stuff  }  

  BaseClass::methodTwo(int a) : BaseClass::methodTwo(a)  {     // other stuff  }  

  SubClass::methodTwo(int a)  {     BaseClass::methodOne(a);     // other stuff  }  

Explanation / Answer

A. is true

Explanation:
A is true because we are trying to call Base Class toString with parameters hence both should be parameterized
C is true because mthod has return type as void and we call baseClass function inside it



A .It will compile without error but probably crash (i.e., generate a run-time error).
C. It has an array bounds violation, possibly causing a fatal runtime error.

Explanation:

Below two statements are correct, Compilation will go successfully but there can be run time error as we are trying to access beyond buffer
