Textbook Question
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.

A cylinder of diameter 10 cm rotates concentrically inside another hollow
cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their
axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to
rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise
Make the following game user friendly with GUI, with some simple graphics
The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forwardHow do you distinguish between hardware and a software problem?
