( MindTap - Cenage )Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high.
Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess).
If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number.
Suppose diff is not 0. Then the program outputs the message as follows:
If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num).
If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num).
If diff is greater than or equal to 15 and less than 30, the…
(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.

1. Concert Tickets Sale and Charity Donation Program
Design and implement a program that prompts the user to input the concert name, ticket price,number of tickets sold, and percentage of the gross amount to be donated to the charity. The sampleoutput is as shown below:
Sample Output:**************************************************************************Concert Name: ………………………………..… The Concert at the ParkTicket Price: …………………………………..… P 49.75Number of Tickets Sold: ………………….…. 5,985 pcs.Gross Amount: ………………………………….. P 297, 753.75Percent of Gross Amount Donated: ……… 13.00%Amount Donated: …………………………..…. P 38, 707. 9875Net Sale: ………………………………………….. P 259, 045.7625**************************************************************************
Note that the concert name such as “The Concert at the Park” must be declared as String.
Input: Concert Name, Ticket Price, Number of Tickets Sold, and Percent of Gross Amount Donated
Output: see sample output above

If ad - bc is 0, report that “The equation has no solution.”arrow_forward(Guess the Number Modification) Modify the program of Exercise 5.32 to count the number of guesses the player makes. If the number is 10 or fewer, print Either you know the secret oryou got lucky! If the player guesses the number in 10 tries, then print Ahah! You know the secret!If the player makes more than 10 guesses, then print You should be able to do better! Why shouldit take no more than 10 guesses? Well, with each “good guess” the player should be able to eliminatehalf of the numbers. Now show why any number 1 to 1000 can be guessed in 10 or fewer tries.arrow_forward(Sort three integers) Write a program that prompts the user to enter THREE integers and display the integers in decreasing order.

- (C++ language)arrow_forward(Removing break and continue ) A criticism of the break statement and the continue statement is that each isunstructured. Actually, these statements can always be replaced by structured statements, although doing so can beawkward. Describe in general how you’d remove any break statement from a loop in a program and replace it with some structured equivalent. [Hint: The break statement exits a loop from the body of the loop. The other way to exit is by failing the loop-continuation test. Consider using in the loop-continuation test a second test that indicates “early exit because of a ‘break’ condition.”] Use the technique you develop here to remove thebreak statement from the application.arrow_forward(Introduction to Python) Include your name and program output in a comment at the top of the script you submit.

Define and call a function called remainder that takes two parameters x and y and prints the remainder when x is divided by y. When y is zero, it should not perform the division and instead print "cannot divide by zero" to prevent the runtime error. Sample output is as follows: Enter a number: x Enter another number: y Remainder of x divided by y is z (you'll fill in the values of x, y and z) Note: upload a script for example labD.py or scriptname.py (do not copy-paste the interactive mode commands)arrow_forward
