The while loop checks the loop-continuation-condition ______.
Select one:
a. First
b. Last
c. Continuously as the loop executes.

2.Create a visitors application that prompts the user for the number of visitors each day for the past 5 days and then displays the average number of visitors per day. (use & to accept new value) Use a for-loop for this question (1 to 5 , 5 iterations). The application output should look like same as following:
Enter number of visitors on day 1: 150
Enter number of visitors on day 2: 220
Enter number of visitors on day 3: 180
Enter number of visitors on day 4: 300
Enter number of visitors on day 5: 320
The average number of visitors is 234
When you know precisely how many times you want to run a piece of code, a for loop is preferable than a while loop.

The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: • alpha-alpha1 • beta-beta1 • gamma-gamma1 • delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: "Login successful."

- Which is correct option for below question. Options are 0,7,none of these. With proper explanationarrow_forward2. Class Exam Results Create a python program that allows a professor to input test results, and calculate the average and high score. The professor is not sure how many students took the exam that day, so you'll need to use a loop that iterates until the professor indicates there are no more students to enter. Include field validation logic to ensure the professor has entered valid test scores. You'll need an accumulator and counter variable to calculate the average. To determine the high, you'll need a variable that stores the current high score as you're iterating thru all the students' results. If a given student's score is higher than the current high score, that becomes the new high score. Initialize the high score to a 0 so the first student's score is automatically higher. Once the loop has ended, you've got all the information you need to print the class average, number of students and the high exam score.arrow_forwardHow do you decide whether a condition should be checked at the top of a loop or at the bottom?arrow_forward

Prompt the user to input a positive integer. Upon input, the program will determine if the number is either a Fibonacci number or not. If a Fibonacci number, then the order of the number in the sequence must be output. If not a Fibonacci number, then the Fibonacci numbers above and below it (including their order in the sequence) must be output. Once it finishes, the program will prompt the user for a new number. The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer.
