Segmentation Fault on Empty Queue

[yashi-here]

Location: Queue_using_stack.cpp Issue: Lack of underflow protection in pop() and peek() functions.

Analysis: The code directly calls s1.top() (or s2.top()) without verifying if the stacks contain any elements. In C++, calling .top() on an empty std::stack is undefined behavior and leads to a Segmentation Fault (program crash). A robust implementation must check if (s1.empty()) before attempting to access the top element.

Impact: Any user calling dequeue on an empty queue will cause the entire application to crash.
