Data Analysis of a Code Snippet in C++

What will be the final contents of the stack after executing the given code snippet?

[10, 9, 8)

[10, 8, 7]

[7, 6, 5)

[5, 6, 7)

Answer:

The final contents of the stack after executing the given code will be [10, 8, 7].

In the first few lines of code, the stack is initialized and elements are pushed onto it. The push() function adds elements to the top of the stack. So, the initial stack will contain [5] after pushing the element 5, and [5, 6] after pushing the element 6.

Next, the pop() function is called twice. The pop() function removes the topmost element from the stack. Therefore, the element 6 is popped first, resulting in the stack becoming [5]. Then, the element 5 is popped, resulting in an empty stack.

After that, three elements are pushed onto the stack using the push() function: 7, 8, and 9. The push() function adds elements to the top of the stack, so the stack becomes [7, 8, 9].

The pop() function is called once more, removing the topmost element 9 from the stack. This leads to the stack becoming [7, 8].

Finally, the element 10 is pushed onto the stack using the push() function. The stack now contains [7, 8, 10].

In the last line of code, the contents of the stack are printed using cout. The stack is displayed as [10, 8, 7], with the topmost element appearing first.

Therefore, the final contents of the stack after executing the given code will be [10, 8, 7].
