Key Insights

• 🎮 The video explains the concept of stack and its importance in programming.
• ✅ The is_empty function checks if the stack is empty by comparing the top value with -1.
• ✅ The is_full function checks if the stack is full by comparing the top value with size - 1.
• ↩️ The get_size function returns the size of the stack using the length variable.
• ❓ These functions are useful for managing and manipulating stacks in programming.
• 🎮 The video emphasizes the significance of the pointer variable "top" in stack operations.
• ↩️ The return types of the functions are boolean, indicating true or false values.

Questions & Answers

Q: What are the three functions discussed in the video for checking stack status?

The three functions discussed in the video are is_empty, is_full, and get_size.

Q: What does the is_empty function return?

The is_empty function returns true if the stack is empty (top = -1) and false if it is not.

Q: What does the is_full function return?

The is_full function returns true if the stack is full (top = size - 1) and false if it is not.

Q: What does the get_size function return?

The get_size function returns the size of the stack using the length variable.

Summary & Key Takeaways

• The video introduces three functions for stack status: is_empty, is_full, and get_size.

• The is_empty function returns true if the stack is empty (top = -1) and false if it is not.

• The is_full function returns true if the stack is full (top = size - 1) and false if it is not.

• The get_size function returns the size of the stack using the length variable.
