Random ranNumber = new Random();
int randomNumber;
randomNumber = ranNumber.Next(min, max);

For this question, you will write a program that prompts the user to enter an integer value between 1 and 1000 (exclusive). Your program should then print out a sequence of numbers between the given value and 1 (inclusive) following the pattern below:For a given number ai,
If ai is even, then ai+1 = floor(ai / 2)
If ai is odd, then ai+1 = 3ai + 1
Your program should stop printing numbers once the sequence reaches the value of 1.
If the user enters a number that is not between 1 and 1000 (exclusive), print "Invalid input." and prompt the user for a number again.
This sequence is referred to as the Collatz sequence. The Collatz Conjecture states that this sequence will eventually reach the value of 1 for any starting number, a fact that has not yet been proven by modern mathematics!
Note: floor(x) means that x should be rounded down to the nearest integer.
Write a program that calculates the estimated hours and minutes for a trip given the number of miles traveled and the speed in miles per hour.
Specifically, write a program that
Welcomes the user to the Travel Time Calculator.
Asks user for number of miles traveled(allow user to enter fractional values)
Asks user for the speed in miles per hour (allow user to enter fractional values)
Calculates the number of hours and minutes for the trip to the nearest integer value. Hint: You can use the built-in function round that rounds a given number to the rounded integer value. e.g. round(4) will return 4, round(4.125) will return 4, round(4.5) will return 4 and round (4.75) will return 5.
Prints the number of hours and minutes for the trip.
Here are some sample runs:
Write a program that computes the molecular weight of a carbohydrate (ingrams per mole) based on the number of hydrogen, carbon, and oxygenatoms in the molecule. The program should prompt the user to enter thenumber of hydrogen atoms, the number of carbon atoms, and the numberof oxygen atoms. The program then prints the total combined molecularweight of all the atoms based on these individual atom weights:Atom Weight(grams I mole)H 1.00794c 12.01070 15.9994For example, the molecular weight of water (H20) is: 2(1.00794) +15.9994 = 18.01528.

- a. Write a program named CheckMonth that prompts a user to enter a birth month. If the value entered is greater than 12 or less than 1, display an error message; otherwise, display the valid month with a message such as 3 is a valid month. b. Write a program named CheckM0nth2 that prompts a user to enter a birth month and day. Display an error message if the month is invalid (not I through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between I and 29 for February). If the month and day are valid, display them with a message.arrow_forwardWrite a program named GuessingGame that generates a random number between 1 and 10. (In other words, in the example above, min is 1 and max is 11.)

When the user types an even number, display the message “Good job!” and then ask for another input. When the user types an odd number, display an error message, "x is not an even number", and then ask for another input. When the user types the sentinel value 999, end the program.arrow_forward

An example of the program is shown below: Enter name for first party >> Pool Party Enter votes received >> 87 Enter name for second party >> House Party Enter votes received >> 54 Enter name for third party >> Surprise Party Enter votes received >> 111 The Pool Party party got 34.523809523809526 percent of the vote The House Party party got 21.428571428571427 percent of the vote The Surprise Party party got 44.047619047619044 percent of the votearrow_forwardWrite a program that generates a random number in the range of 1 through 1000, and asks the user to guess what the number is. If the user guess is higher than the random number, the program should display Too high, try again. If the users guess is lower than the random number, the program should display Too low, try again. If the user guesses the number, the application should congratulate the user and generate a new random number so the game can start over. If the user doesn't want to continue the game the user should type an appropriate stop symbol to terminate the program (such stop conditions were discussed in the class). For each game iteration, count the number of guesses made by the user and display them. The program should contain the following functions: check_guess(): this function checks if the user's guess is lower, higher or equal to the random number. random_gen(): function that generates one random number for one game iteration main(): the function where the program…arrow_forwardWrite a program that allows a user to enter any number of student quiz scores, as integers, until the user enters 99.

- This is the question - Write a program that inserts parentheses, a space, and a dash into a string of 10 user-entered numbers to format it as a phone number.

After getting your choice, the program asks for two numbers, then performs the requested operation, prints out the expression evaluated and its result. The program should accept only the offered menu choices. It should use type float or double for the numbers and allow the user to try again if he or she fails to enter a number. In the case of division, the program should prompt the user to enter a new value if 0 is entered as the value for the second number.
