- In Chapter 11, you created the most recent version of the MarshallsRevenue program, which prompts the user for customer data for scheduled mural painting. Now, save all the entered data to a file that is closed when data entry is complete and then reopened and read in, allowing the user to view lists of customer orders for mural types.Please help me write the following function (please see the attached photos for context of the problem): find_treasure(start_map_num): Takes an integer between 0 and 9 as input. Loads the corresponding map file, and starts following the trail (at position 0, 0 of that file) as described above. Continues following the trail through other map files as needed. Places an 'X' at the conclusion of the trail and saves the updated treasure map to a new file with 'new_' prepended to the current map filename. Returns a tuple of the row and column index where the 'X' was placed in that file.FILE* inFile = fopen("filenam.txt", "r"); Given the above code segment, which of the following would output "FILE NOT FOUND" if the file could not be opened? Group of answer choices if(inFile == NULL) { printf("FILE NOT FOUND"); } if(inFile) { printf("FILE NOT FOUND"); } if(!inFile->is_open()) { printf("FILE NOT FOUND"); } None of these ============= What does sscanf do?

That way, no changes are lost, even if the program crashes laterPHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…
- Case Problems - 1- In Chapter 8, you modified the EventDemo program for Carly’s Catering to accept and display data for an array of three Event objects. Now, modify the program to use an array of eight Event objects. Prompt the user to choose an option to sort Events in ascending order by event number, number of guests, or event type. Display the sorted list, and continue to prompt the user for sorting options until the user enters a sentinel value. Save the file as EventDemo.java.public int readBalance(int acctId) throws SQLException { // TODO: Read balance from given account id using a PreparedStatement // Throw the following exception if the account is not found: // throw new SQLException("Account "+acctId+" not found."); // Use the con instance variable for the JDBC connection. // Make sure to commit() if success or rollback if exception or account is not // found. return 0; }3.

- You are asked to develop an application that does the following: 1. The application should read the records from the user (String Name and String ID) and write them into a text file named (Employees.txt). The text file should be structured as follow: Sara Ahmad 123123 121122 John 123 Mohammed 12345 2. The user is asked to enter the values for records untih the user enters the value zero (0) for the name then the loop should be terminated. 3. Then, the application should read and check each record in the text file and print out all the records that have an ID less than 6 digits. Note: • The file should be opened only once for writing otherwise the previous content will be truncated. • Make sure you handle all expected exceptions that might be caused by the provided code.

ValueError NameError IndexError KeyErrorMusic App 1. practise file I/O and exception handling; 2. practise String processing. Aim: Task: Create a Java application that transcripts a simple song score sheet. The program asks user for filename of a text file that contains a simple song score sheet in this format: Sample song score sheet 1, song1.txt: #simple song with assumed time signature = 4 d1mls202s 1mld2o2 d1rimlfls 301s1f1m1rld4 Lines beginning with a hash #' is a comment line. A song contains one or more lines of musical notes, d, r, m, f, s, l, tand also o meaning "Off" or rest. Each single character note is followed by a single digit integer in [1 – 4], denoting the duration of the note in number of beats. After transcription, the program outputs the melody on the screen as well as to another text file: Melody output 1, on screen AND in melody_song1.txt: #simple song with assumed time signature Do Me So- Off- So Me Do Re Me Fa| So-- Off = 4 Do- Off- | So Fa Me Re Do--- | The default time signature is 4 beats per…
