1.Adam is writing a program that: 1) has the user guess a number and 2) tells the user how many guesses it took to get the correct answer. But when Adam tests the program, it always outputs that it took the user one guess, even when it takes many guesses. What error did Adam most likely make, and how should it be fixed?

2.The difference between a for loop and a while loop is that a for loop is a loop that happens for a certain number of times. A while loop happens until a certain condition is met. How do you know when to use each one? Give specific examples in your answer.
3.What are some real-life programs or websites you’ve used that have condition-controlled loops and count-controlled loops?
4.Your friend is trying out your new password generator program. She wants to know how it works. How would you explain it to her? Keep in mind that she does not know Python code. Make sure to use good communication techniques.
5.What are some situations where you might find it useful to use the ! symbol in a program?

1. Adam most likely made the error of not updating the counter variable that tracks the number of guesses. To fix this, Adam should increment the counter variable each time the user makes a guess until the correct answer is guessed.

2. You would use a for loop when you know exactly how many times you want to iterate through a block of code. For example, if you want to print numbers 1 to 10, you would use a for loop with a range of 1 to 11. You would use a while loop when you are unsure of how many iterations you need and are reliant on a condition to exit the loop. For example, if you want to keep asking a user for input until they enter a specific value, you would use a while loop with a condition checking for that value.

3. Real-life programs or websites that use condition-controlled loops include online shopping websites that keep adding items to the cart until a user is ready to checkout. Count-controlled loops can be found in programs that need to perform a certain task a specified number of times, such as displaying a list of items in a menu.

4. To explain the password generator program to your friend, you can say that the program generates a strong and unique password using a combination of letters, numbers, and special characters. It allows you to customize the length and complexity of the password to meet your security needs.

5. The ! symbol in a program is often used as a logical NOT operator. It is useful in situations where you want to negate a condition, for example, checking if a variable is not equal to a certain value. It can also be used to invert the truth value of a statement, making it useful for conditional statements.
