What is the definition of Iteration?
The process of repeating a block of code until a condition is met.
What is a while loop?
A loop that executes a block of code repeatedly as long as a specified condition remains true.
What is an infinite loop?
A loop where the condition always evaluates to true, causing the loop to run indefinitely.
What is a sentinel value in a loop?
A specific input that signals the end of the loop.
What is a flag variable in a loop?
A boolean variable used to control the execution of a loop, typically set to true initially and false to exit.
What does the break statement do in a loop?
Immediately exits the loop, regardless of the loop condition.
What does the continue statement do in a loop?
Skips the rest of the current iteration and jumps to the next iteration.
What is an Exception?
An error that occurs during program execution.
What is a try block?
A block of code that might throw an exception.
What is a catch block?
A block of code that handles specific exceptions thrown in the try block.
What is a finally block?
A block of code that always executes, regardless of exceptions.
What are the differences between break and continue statements?
break: Exits the loop entirely. | continue: Skips the current iteration and proceeds to the next.
What are the differences between a sentinel-controlled and a flag-controlled while loop?
Sentinel: Loop ends based on a specific input value. | Flag: Loop ends based on a condition changing a boolean variable.
What are the differences between try, catch, and finally blocks in exception handling?
try: Encloses code that might throw an exception. | catch: Handles a specific exception. | finally: Always executes, regardless of exceptions.
How are while loops used in input validation?
To repeatedly prompt the user for input until a valid input is provided.
How are while loops used in game development?
To maintain the game loop, continuously updating the game state and rendering the graphics.
How are while loops used in data processing?
To iterate through large datasets, performing operations on each element until the end of the data is reached.
How can while loops be used to simulate real-world processes?
By modeling repetitive tasks or events that continue until a specific condition is met, such as a machine running until it runs out of material.
How are while loops used in file processing?
To read and process data from a file line by line until the end of the file is reached.
How is exception handling used in real-world banking systems?
To handle situations like insufficient funds, invalid account numbers, or network errors during transactions, ensuring data integrity and system stability.
How are while loops used in operating systems?
To continuously monitor system resources and respond to events, such as handling user input or managing processes.
