Chapter 18: Problem 32

T F The STL stack container’s pop operation does not retrieve the top element of the stack, it just removes it.

Short Answer

Expert verified
Answer: True (T)

Step by step solution

01

1. Understand the STL stack container

The Standard Template Library (STL) provides a stack container - a data structure that behaves like a collection of elements, with two main operations: pushing elements into the stack and pop them out of the stack in a last-in, first-out (LIFO) manner.
02

2. Recall the two main operations: push and pop

The two main operations for a stack container are: - push: Adds a new element to the top of the stack. - pop: Removes the top element from the stack.
03

3. Analyze the pop operation

The pop operation in the STL stack container removes the top element from the stack. However, it does not return the value of the removed element.
04

4. Evaluate the given statement

Based on our understanding of the pop operation, it is correct to say that the pop operation does not retrieve the top element of the stack; it just removes it.
05

5. Conclusion

The given statement is True (T).
