Question
Transcribed Image Text:5. A prime number is a number that is only evenly divisible by itself and 1. For example, the
number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, how-
ever, is not prime because it can be divided evenly by 1, 2, 3, and 6.
Write a Boolean function named is_prime which takes an integer as an argument and
returns true if the argument is a prime number, or false otherwise. Use the function in a
program that prompts the user to enter a number then displays a message indicating
whether the number is prime.
6. In another program, use the function you wrote in question 5 to print the prime numbers
between 1 and 100 using for loop.

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

1. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime.Tip:Recall that the % operator divides one number by another and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.

Question:A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.
Design a Boolean function called isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise. Use the function in a program that prompts the user to enter a number and then displays a message indicating whether the number is prime. The following modules should be written:
- getNumber, that accepts a Ref to an integer, prompts the user to enter a number, and accepts that input
- isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise
- showPrime, that accepts an integer as an argument , calls isPrime, and displays a message indicating whether the…

Speed Detector (Toy Problem)
Write a program that takes as input the speed of a car e.g 80. If the speed is less than 70, it should print “Ok”. Otherwise, for every 5 km/s above the speed limit (70), it should give the driver one demerit point and print the total number of demerit points.
For example, if the speed is 80, it should print: “Points: 2”. If the driver gets more than 12 points, the function should print: “License suspended”.

An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 = 1 + 2 + 3. Write a function named perfect that determines if parameter number is a perfect number or not. Use this perfect function in a program that determines and prints all the perfect numbers between 1 and 1000.Also print the factors of each perfect number to confirm that the number is indeed perfect.

Write a function perfect that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect. Challenge the power of your computer by testing numbers much larger than 1000.

Given person_is_old(age) which returns True or False based on the incoming age as an integer. Write a function that uses the one mentioned above so that it prints “Go to work!” if the person is not old and “You deserved to have a long vacation” otherwise. Your function must also accept the age as its argument.
