switch_player(): we will allow the players to choose their own names, but for our purposes, it is easier to think of them as number (0 and 1, for indexing purposes). We will display their names to them on the screen, but in the background, we will keep track of them based on their number. This function should take 1 argument, an integer (either 0 or 1) representing the player and should return the opposite integer (1 if 0 is entered and 0 if 1 is entered). This is a simple function, but it will make our code cleaner later. Use your constants! Using Thonny
99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.
Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.
Instructions: In the code editor, you are provided with a treasureChestMagic() function which has the following description: Return type - void Name - treasureChestMagic Parameters - an address of an integer Description - updates the value of a certain integer randomly You do not have to worry about how the treasureChestMagic() function works. All you have to do is ask the user for an integer and then call the treasureChestMagic() function, passing the address of that integer you just asked. Finally, print the updated value of the integer inputted by the user. Please create a main code for my function that works with this. This is my code: #include<stdio.h>#include<math.h> void treasureChestMagic(int*); int main(void) { // TODO: Write your code here return 0;} void treasureChestMagic(int *n) { int temp = *n; int temp2 = temp; *n = *n + 5 - 5 * 5 / 5; temp2 = (int) pow(2, 3); if(temp % 3 == 0) { *n = temp * 10; } else if(temp %…

Overview: A new bank wants to make a simple application to keep track of all accounts and transactions. In this TMA, it is required to help the bank manager implement the required application. Requirements: After a quick meeting with the bank manager, you got the following information: It is required to store all bank accounts in one collection and all the transactions happened in another collection. Each account has a unique account number, a holder and balance. There is a specific prefix (common for all accounts) that should be added to the holder's civil id to create the unique account number. In addition, it is not allowed for a holder to have more than one account. Furthermore, only three transactions are allowed on any account: deposit, withdrawal and transfer money to another account. Each holder has a unique civil ID (national id), a name and other attributes (add at least 2 attributes from your choice). For each transaction, it is required to store the account(s) affected,…

Pendant Publishing edits multi-volume manuscripts for many authors. For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work. The flowchart must include a call symbol, at the beginning, to redirect the input to the external data file. create a solution algorithm using pseudocode create a flowchart using RAPTOR
