C++ static member functions: does using this-> inside a static method compile? Examine and predict the program's behavior.\n\n#include<iostream.h>\nclass CuriousTab\n{\n static int x;\npublic:\n static void SetData(int xx)\n {\n this->x = xx; // attempt to use this in a static function\n }\n static void Display()\n {\n cout << x;\n }\n};\nint CuriousTab::x = 0;\nint main()\n{\n CuriousTab::SetData(22);\n CuriousTab::Display();\n return 0;\n}

Introduction / Context:
This question checks your understanding of C++ static member functions and the absence of the implicit this pointer inside them. It asks whether referencing this->x in a static method is legal.

Given Data / Assumptions:

• x is a static data member.
• SetData and Display are static.
• SetData incorrectly uses this->x.

Concept / Approach:
A static member function is not associated with any particular object instance, so it has no this pointer. Any attempt to use this inside a static member function is ill-formed and rejected by the compiler.

Step-by-Step Solution:
Note the signature static void SetData indicates no object context.Inside it, this is referenced, which is invalid.The compiler issues an error; execution never occurs.

Verification / Alternative check:
Replace this->x with CuriousTab::x (qualified name) or simply x and the code will compile and print 22.

Why Other Options Are Wrong:
They assume successful compilation or run-time behavior. The error arises at compile time.

Common Pitfalls:
Confusing static context with instance context and trying to use this where it does not exist.

Final Answer:
The program will report compile time error.
