Introduction to Computer Systems Project 1 Due: February 09, 2023 by 5:00 PM Spring 2023 Introduction: xxd command in Linux creates a hex dump of a given file or standard input. It's simple. For example, suppose you have a text file 'test.txt' with contents as shown below: The isprint() function checks whether a character is a printable character or not. Check more information in: https://www.programiz.com/c-programming/library-function/ctype.h/isprint Here's how you can use xxd to convert the file contents into hex: $ xxd test.txt And here's the output: 00000000: 5468 6520 6973 7072 696e 7428 2920 6675 00000010: 6e63 7469 6f6e 2063 6865 636b 7320 7768 00000020: 6574 6865 7220 6120 6368 6172 6163 7465 00000030: 7220 6973 2061 2070 7269 6e74 6162 6c65 00000040: 2063 6861 7261 6374 6572 206f 7220 6e6f 00000050: 742e 0a43 6865 636b 206d 6f72 6520 696e 00000060: 666f 726d 6174 696f 6e20 696e 3a20 6874 00000070: 7470 733a 2f2f 7777 772e 7072 6f67 7261 00000080: 6d69 7a2e 636f 6d2f 632d 7072…
Exercise 2: Solve the programming exercise P10.19 on Page 536 on the book. Note: coin class provided in the Моodle. Write a program that reads in a set of coin descriptions from a file. The input file has the format coinNamel coinValuel coinName2 coinValue2 Add a method void read(Scanner in) throws FileNotFoundException to the Coin class of Section 7.2. Throw an exception if the current line is not properly formatted. Then implement a method static ArrayList readFile (String filename) throws FileNotFoundException In the main method, call readFile. If an exception is thrown, give the user a chance to select another file. If you read all coins successfully, print the total value.

1-Write a JAVA program that reads an array from input file and invokes twodifferent methods Sort and Max ,that sorts the elements of the array and findsthe Max element and writes out the resulted array in to output file . Usetwo interfaces for methods and throw Exception Handling for Out Of Boundindex for the array.
Exception Project JAVA Create a Java program that searches for a student’s ID or name in a text file, complete the findID() and findName() functions. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains a name and ID separated by a space. Function findID() has two parameters: a student's name (string) and the text file's contents (infile, input file variable). The function findID() returns the ID associated with the student's name if the name is in the file, otherwise the function throws a runtime error with the message "Student ID not found for studentName", where studentName is the name of the student. Function findName() has two parameters: a student's ID (string) and the text file's contents (infile). The function findName() returns the name associated with the student's ID if the ID is in the file, otherwise the function throws a runtime error with the message…
10-8. Cats and Dogs: Make two files, cats.txt and dogs.txt. Store at least three names of cats in the first file and three names of dogs in the second file. Write a program that tries to read these files and print the contents of the file to the screen. Wrap your code in a try-except block to catch the FileNotFound error, and print a friendly message if a file is missing. Temporarily rename each of your files, and make sure the code in the except block executes properly. Make sure an exception is caught for either file missing.

Java Exceptions Write a program that accepts an integer N which serves as the size of an array. Ask for N number of elements. After, continuously ask for user input index. Mark the element at that index as zero. If the user gives an invalid index, throw the appropriate exception and print "Illegal index!". The program ends once an exception is thrown or once the array contains only zeroes. Lastly, print the array elements separated by space. Inputs 1. Multiple lines of integer Sample Output Enter N: 5 Enter element 1: 1 Enter element 2: 2 Enter element 3: 3 Enter element 4: 4 Enter element 5: 5 Enter index: 1 Enter index: 2 Enter index: 3 Enter index: 4 Enter index: 5 Illegal index! 1 0 0 0 0
CHALLENGE ACTIVITY 420468 2512078.qx3zqy7 Consider a comma-separated file that contains student names and scores such as the following: Jane Lee, 100, 98, 97, 100 Aaron X. Schmidt, 37, 42, 49, 54 Frank von Tardy, 2, 3, 10, 7 8.19.4: Rearrange the lines to compute the total score for a single student. We can read the file one line at a time and use an istringstream object to process the scores. To get the position of the first comma, simply read words from the input stream until the word ends with a comma. Then, read and sum the numbers remaining on the line. Use get to remove the commas following each number. Rearrange the lines below to compute the total score for a single student. Assume that each student has at least one score. Mouse: Drag/drop Keyboard: Grab/release Spacebar (or Enter). Move 100. Cancel Esc Unused total= total + score; while (getline(in_file, line)) in.str(line); in >> word; char ch; in.get(ch); in >> word; while (word [word.size()-1] != ',') total = 0; while (in…

Identify what type ofexception each will cause.Trying to add incompatible variables, as inadding 6 + ‘a’Referring to the 12th item of a list that has only 10itemsUsing a value that is out of range for a function’sinput, such as calling math.sqrt(-1.0)Using an undeclared variable, such as print(x) when x has not been definedTrying to open a file that does not exist, such asmistyping the file name or looking in the wrongdirectory.
Complete a program that reads a vector index as input and outputs the element of a vector of 10 names at the index specified by the input. Use a try block to output the name and a catch block to catch any out_of_range exceptions. When an out_of_range exception is caught, output the message from the exception object and the first element in the vector if the index is negative or the last element if the index is greater than the size of the vector. Hint: Format the exception outputs using the what() function from the exception object. Do not hard code the exception messages. Ex: If the input of the program is: 5 the program outputs: Jane Ex: If the input of the program is: 12 the program outputs: Exception! vector::_M_range_check: __n (which is 12) >= this->size() (which is 10) The closest name is: Johnny Ex: If the input of the program is: -2 the program outputs: Exception! vector::_M_range_check: __n (which is 18446744073709551614) >= this->size() (which is 10) The closest…
