isPrime Function
A prime number is an integer greater than 1 that is evenly divisible by only 1 and itself. 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 by 1, 2, 3, and 6.
Write a Boolean function named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, and false otherwise. Demonstrate the function in a complete program.
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.

- (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.arrow_forward(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:arrow_forward***IN PSUEDOCODE ONLY - not a real programming language!!*** 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…arrow_forward
- C Programming Language Define an enumerated data type Month. Write a function that takes a Month someMonth and aninteger n as parameters. Your function must return the month which is n days after someMonth.Note: Assume that all months have 30 days.Example : If we call the function with parameters someMonth=January and n=95 then it must return April.arrow_forwardSpeed 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”.arrow_forward(Perfect Numbers) An integer number is said to be a perfect number if its factors, including1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 =1 + 2 + 3. Write a function isPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1and 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.arrow_forward
- Programming Language : R programming (R Studio) A twin prime is a prime that has a prime gap of two. Sometimes the term twin prime isused for a pair of twin primes. For example, the five twin prime pairs are (3, 5), (5, 7),(11, 13), (17, 19) and (29, 31). Write a function that returns the number of all twin primepairs between 1 and a given number n.arrow_forwardC++ : Write a function that has three C++ strings as parameters. It searches the first parameter to find the secondparameter (as a substring) and replaces it with the third parameter. It returns the changed first parameter if the substringcan be found; otherwise, it returns the original first parameter. Test your function in a program.arrow_forwardPlease before you start this program should be written on python program 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 primearrow_forward
- (Coin Tossing) Write a program that simulates coin tossing. For each toss of the coin theprogram should print Heads or Tails. Let the program toss the coin 100 times, and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip that takes no arguments and returns 0 for tails and 1 for heads. [Note: If the programrealistically simulates the coin tossing, then each side of the coin should appear approximately halfthe time for a total of approximately 50 heads and 50 tails.]arrow_forwardDesign a function that accepts an integer argument and returns the sum of all the integers from 1up to the number passed as an argument. For example, if 50 is passed as an argument, thefunction will return the sum of 1, 2, 3, 4, . . . 50. Use recursion to calculate the sum.arrow_forwardCase Study – Finding Factors Create a solution with functions (modules) and control structures for a program that reads a positive and non-zero integer entered by an interactive user and prints out all of its factors in ascending order. For example, when the user enters 50, the program should print 2 5 5 because 2 * 5 * 5 = 50; when the user enters 60, the program should print 2 2 3 5 because 2 * 2 * 3 * 5 = 60 when the user enters 150, the program should print 2 3 5 5 because 2 * 3 * 5 * 5 = 150 User should be able to repeat procedure as many times as they like. Write and test the module that reads a positive and non-zero integer.arrow_forward
