Chapter 4, Problem 7PP
Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a
int hours, minutes;
bool isAM;
For example, to represent 11:50 PM, you would store:
hours =11
minutes = 50
isAM = false;
This means that you need six variables to store a start and future time. Write a program that allows the user to enter a start time and a future time. Include a function named computeDifference that takes the six variables as parameters that represent the start time and future time. Your function should return, as an int, the time difference in minutes. For example, given a start time of 11:59 AM and a future time of 12:01 PM, your program should compute 2 minutes as the time difference. Given a start time of 11:59 AM and a future time of 11:58 AM, your program should compute 1439 minutes as the time difference (23 hours and 59 minutes).
You may need “AM” or “PM” from the user’s input by reading in two character values. (Display 2.3 illustrates character input.) Characters can be compared just like numbers. For example, if the variable aChar is of type char, then (aChar == ‘A’) is a Boolean expression that evaluates to true if aChar contains the letter A.

Airline companies apply baggage restrictions for their passengers. An
airline company has decided to apply a 10kg limitation for
passengers' hand luggage and 20kg for their normal baggage. When
passengers arrive, they enter their hand and normal luggage weight
from the keyboard. If passengers exceed their normal baggage
allowance of 10 dollars per gram, they pay 12 dollars per kg.
Accordingly, write the program that calculates the baggage price of
the airline they will go to according to the baggage values entered by
the arriving passenger and keeps this from closing the program for
each passenger. Note: If hand and normal baggage allowances are
stretched below the maximum value, the payment amount will be
considered not negative. An example printout is given on the right.

A laborant in a laboratory does a number of antigen tests in one day. Write a program that
simulates the number of antigen tests done in a day in a laboratory, displays the number of
positives and negatives, and calculates the % of positives in one day. Your program needs
to first generate a random number that will show the number of tests done in a day. One
laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one).
Then for each of the tests, your program needs to generate a random number to show
whether they are positive or negative. In order to write this program, you need to have the
following three functions used by the main function:
test result (void): This function generates a test result. It should randomly
return either one or zero. 1 means positive test result and 0 means negative test result.
float positive percentage (int,int) : This function takes the total number of
positives and the total number of tests and returns the % of positives.…
Welcome to the era of Aladdin and the great magic lamp. This is 1st of January and Aladdin will be in jail for one year. He was recently caught for helping forty thieves. Now he has nothing to do. But he knows that Jasmine is waiting for him. At some point he got an idea to give Jasmine a magical program that can find intervals of months from a year. This allows her to easily determine how long it will take for Aladdin to get out. Then Aladdin rubs the magic lamp and The Genie appears. Then he asked The Genie to make such a magical program.
Unfortunately the Genie doesn't know programming and he wants your help to create that magical program. Genie will give you N as the day of the year and you have to print in which month that day is.
Input Format
Input will contain one line with a single integer N, day of the year.
Constraints
1 <= N <= 365
Output Format
Print a single line containing the name of month. Be careful about the newline ('\n') at the end.

- In python, a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to a random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to b) Modify the application to allow the player to continue until there are 0 points left. At the end of the game, display the number of guesses the user took before running out of points.arrow_forwardThe monthly payment for a givenloan pays the principal and the interest.

A quarter is equivalent to 3 months. Assume that the account is created at the beginning of a year (i.e. January 1). The year will be entered at run time through the keyboard. The account has an initial principal that is entered at run time through the keyboard. No deposit or withdrawal is made within the one-year period. The interest is compounded quarterly which means that the interest earned for the first quarter will form part of the principal for the second quarter, the interest earned for the second quarter will form part of the principal for the third quarter and so on. The annual interest rate is 5%. The interest rate for a quarter is computed by dividing the annual interest rate by 4 since there are four quarters in a year.

- 1. For this problem, you are going to design a game for the children to teach them about numbers. You are going to take numbers as input from the user as long as he has not entered an even number. If enters odd number, ask him again to give input. When he enters an even number, print that the number is even, and you have won. The program should include the following specifications: É) This will go on, until the user gives an even number input F) When you find an even number, print, "You win! is an even number"arrow_forwardIn python The Nim game. Write a program for a two-player version of the game Nim: a human player will play against the computer. The game is simple: players take turns removing from 1 to 4 sticks from a pile of 13 sticks; the player who picks up the last stick wins the game. Here’s some pseudocode for the Nim game. Start by initializing some variables that will allow you to keep track of the state of the game: One variable should record how many sticks there are left in the pile; initially, this variable must be initialized to 13. There are two players in the game, who take turns. To remember who’s turn is next, use a variable with two states (= values). Say the variable is 1 if the human player is next, and it is 2, if the computer’s turn is next. Pick randomly the player who should start the game. Then, start the main loop of the game: the game should continue for as long as there still are sticks (at least one) to pick. In each repetition of the game loop, one player will play…arrow_forwardusing a C++ program code the problem, The game of "23" is a two-player game that begins with a pile of 23 toothpicks. Players take turns, withdrawing either 1, 2 or 3 toothpicks at a time. The player to withdraw the last toothpick loses the game. Write a human vs. computer program that plays "23". The human should always move first. When it is the computer's turn it should play according to the following rules: If there are more than 7 toothpicks left, then the computer should withdraw a random number of toothpicks (from 1 to 3). Use the rand() function, as demonstrated in class to produce this number.. If there are 2, 3 or 4 toothpicks left, then the computer should withdraw enough toothpicks to leave 1. If there is 1 toothpick left, then the computer has to take it and loses. When the human player enters the number of toothpicks to withdraw, the program should perform input validation. Make sure that the entered number is between 1 and 3 (inclusive) and that the player is…arrow_forward
