Lecture Notes on Code Implementation

Overview of Constructors

• Default Constructor:
  • Sets the container to a null and empty vector.
• Non-default Constructor:
  • Initializes the container variable (vector) to the value on the right-hand side.
• Move Constructor:
  • Deletes the old right-hand side and utilizes move semantics to transfer ownership.
• Copy Constructor:
  • Similar to the non-default constructor but incorporates std::move for the right-hand side.
• Destructor:
  • Clears the container but performs minimal tasks.

Operator Overloading

• Purpose:
  • Overloads operators to copy while leaving the original intact.
• Const Stack Implementation:
  • Utilizes move semantics to eliminate the old instance while copying to the return instance.

Swap Functionality

• Functionality:
  • Uses the built-in container.swap() function for swapping elements.

Pushback Functionality

• Pushback Method:
  • Differentiates between normal pushback and std::move.
  • Ensures old memory is released when moving elements.

Pop Functionality

• Check for Empty Container:
  • Verifies if the container is not empty before popping to avoid errors.
  • Executes container.pop_back() if conditions are met.

Size and Empty Checks

• Size Method:
  • Returns the current size of the container.
• Empty Method:
  • Checks if the container has been instantiated and contains elements.

Testing the Functions

• Testing Pop Function:
  • Creates a stack with four elements and tests the pop function.
  • Monitors the size decrement while capacity remains unchanged.
• Testing Pop on Empty Stack:
  • Ensures the pop function's behavior when invoked on an empty stack.
• Success Rate:
  • Reports a 100% success rate for stack operations during tests.
