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…
WriteaC++programthatpromptstheusertoenterafilenamethatcontains the total mark of students. Each line in the input file contains a student name followed by the student’s total mark. The program should ask the user for the passing threshold (i.e. student whose total mark is greater than or equal the threshold will pass the course) and copy the students who pass the course to a new file (the name of the output file is specified by the user). Moreover, the output file should be format so that all the marks are displayed with two digits after the decimal point. The width for the names and marks fields should be eight and seven, respectively. A sample input and output files are shown below (the passing mark in this sample is assumed to be 60).

Exercise 2 (30/40): Write a program that reads in a set of coin descriptions from a file. The input file has the format coinNamel value is coin Valuel coinName2 value is coinValue2 Add a method to your program that receives file content and writes back to another file statistics about the coins. Sample input file Riyal value is 25 Baisa value is 6.0 BHR value is baisa value is 5.30 Riyal value is 23.5 Sample output file Riyal = 24.25 Baisa =5.65 BHR = 9.5 In the solution 1. use the coin class provided on Moodle. 3. Handle any two exceptions to make sure the input file holds the correct transactions format (FileNotFoundException is not one of them) Information: 9.5 ● Illegalargumentexception: The IllegalArgumentException is an unchecked exception in Java that is thrown to indicate an illegal or unsuitable argument passed to a method. It is one of the most common exceptions that occur in Java. InputMismatchException: The InputMismatchException generally occurs when working with Java…
Exercise 5: Write a Python program that reads each line of an input file original.txt and saves in a file called analysis.txt the line number, the number of words and characters found in that line without counting punctuations separating the words or found at the end of the line. For example, if the original.txt file is: In COMP2101, the students learn basic programming skills. Which includes: arithmetic and logical expressions, decisions, and loops. They will also learn how to read and write from keyboards and files. The file analysis.txt will contain Line1, 8 words and 48 characters Line2, 9 words and 61 characters Line 3, 13 words and 55 characters
Don't send a plagiarised response otherwise I'll give you multiple downvotes and will report for sure. I need a correct and unique answer for this.
6. Write a program that reads (up to 100) temperature values from a file called input.txt. Read the temperature values and the name of the city into two arrays. Use functions to determine the city that has the maximum temperature, the minimum temperature. The program outputs all results to another file called output.txt. Output.txt + X input.txt* Muscat has the maximum temperature which is 42 Muscat 42 Salalah has the minimum temperature which is 27 Sohar 38 Salalah 27 Sur 29 Seeb 40 Nizwa 39 Mutrah 41 Ibri 38
Write a function that reads all the numbers from a file into an array. The file is already open and there is no bad data in the file. The data is one number per line and an unknown number of lines of data. The function should read data until either end of file is detected or the array is full. Prototype void readData( ifstream& iFile, double numbers[ ], int size, int& count); iFile - already open ifstream numbers[ ] - array to store data size - the size of the array. count - the number of values read and must be set by the function before returning.

6. Write a program that will randomly generate 500 integer numbers in the range -249 to 250. Write thosenumbers in a text file named “in.txt”. Now Sort (in ascending order) all the integer numbers in the file “in.txt”using Buuble Sort. Save the sorted output into another text file named “out.txt”. (Try to write separatefunction for SWAP and BUBBLE_SORT and call them from main function.)
A program stores the prime numbersin a file named PrimeNumbers.dat.
