In C++ (post-increment on a referenced argument), both parameters alias the same variable. Predict the printed pair. #include<iostream.h> class CuriousTab { int x, y; public: void SetValue(int &xx, int &yy) { x = xx++; y = yy; Display(); } void Display() { cout << x << " " << y; } }; int main() { int x = 10; int &y = x; CuriousTab objCuriousTab; objCuriousTab.SetValue(x, y); return 0; }

Introduction / Context: This tests post-increment behavior when two reference parameters alias the same object. The order of assignments matters: store x = xx++ first, then copy y = yy after the increment.

Given Data / Assumptions:

• At call time, xx and yy both reference the same int x (initially 10).

Concept / Approach: Post-increment returns the old value, then increments the underlying object. Because yy aliases the same object, reading yy after the increment observes the new value.

Step-by-Step Solution:

Verification / Alternative check: Swapping the two assignment lines would change the observed pair because the timing of the increment differs.

Why Other Options Are Wrong: They misread pre/post semantics or ignore that both references alias the same object.

Common Pitfalls: Expecting both fields to be 11 due to misunderstanding of when the incremented value is used.

Final Answer: The program will print the output 10 11.
