Write a C program which opens file1 which only contains this line: abc and then opens the empty file2. Your program should write cba to file2. You may only declare one uninitialized char variable and may not have any loops, con- ditionals, or include statements, or library functions, and may not use lseek or do any arithmetic with ascii codes. Solve the problem by using system calls directly.

- I’m having trouble with a computer science lab (C++) assignment and just need help figuring it out. It needs to include .cpp files and .h file(s).I have a text file and I want to read it in C++. variables to use: fname, lname , Id nr, Gender and all third line which is an address The file is : Tommy James 23456731667 Streetname 45 , 154 23 Georgia John Andersson 3456723464 Streetname 12 , 231 32 Las Vegas Kim Larsson 3456312653 Streetnamn 15, 231 56 Florida If we Said the 8th digit in ID number is showing the Gender of the person. By %2== 0 it's Male The output should be: Lname Fname [F] address Is there possible to create a program in C++ with the previously output. lname , fname [F]Adress Without have a problem with Las Vegas word. I have a hard time to figure how I can do the third line in the file. They read to word Las and then the compiler shows terminate called after throwing an instance of ' std::invalid_ argument ' what (): stoi aborted so I figured that the problem I have in one line the city is two word.Rahul created a file and he saved some points from his notes to that file but while saving the points he added some n characters as hints at the end. Now he wants to create a new file in which he wants to copy that hints from file 1 to a new file so he can use that new file for exam preparation. Write a program in c++ to complete the Rahul's task.
- Based on the output below, create a C++ program that will include the new and delete operator. Interpret your program; you may include comments in interpreting your own program.SAMPLE OUTPUT: [Enter your own grades]Enter the number of grades to be processed:Enter a grade: 87Enter a grade: 88Enter a grade: 89Enter a grade:90An array was created for 4 integers The values stored in the array are:87888990Instruction: Write a C++ PROGRAM INCLUDE THE HEADER FILE, MAIN CPP, AND BSTREE.CPP and the text file. Don't use AVLTree. There is a real program developed by a computer company that reads a report ( running text ) and issues warnings on style and partially corrects bad style. You are to write a simplified version of this program with the following features: Statistics A statistical summary with the following information: Total number of words in the report Number of unique words Number of unique words of more than three letters Average word length Average sentence length An index (alphabetical listing) of all the unique words (see next page for a specific format) Style Warnings Issue a warning in the following cases: Word used too often: list each unique word of more than three letters if its usage is more than 5% of the total number of words of more than three letters Sentence length : write a warning message if the average sentence length is greater than 10 Word length :…You need to write a program in C that will allow a teacher to store, update and view the grades of multiple students. The program should perform the following operations: Add a new student and their grades for different subjects. View the grades of a particular student. Update the grades of a particular student. View the average grades of all students.The program should store the following information for each student: Student name (string) Roll number (integer) Grades for 5 subjects (integers)The program should implement a menu-driven interface for the user to perform the above operations. The program should continue to run until the user selects to exit.Constraints: The student name should not exceed 50 characters. The roll number should be a positive integer and should be unique for each student. The grades should be integers in the range [0, 100].
- Write a C++ program that reads data from an input file, takes the data and computes student grades for an assignment by converting the raw score to a percentage given each student's score and the total points. The final score must be rounded up to the nearest whole value using the ceil function in the header file and displayed as a percentage. You must also display the floating-point result up to 5 decimal places. You must use at least 2 functions: one to print the last name of the student and another function to compute and print the percentage as well as "Excellent" if the grade is greater than 90, "Well Done" if the grade is greater than 80, "Good" if the grade is greater than 70, "Need Improvement" if the grade is greater than or equal to 60, and "Fail" if the grade is less than 50. The main function is responsible for reading the input file and passing the appropriate arguments to your functions.Write a C++ program that reads data from an input file, takes the data and computes student grades for an assignment by converting the raw score to a percentage given each student's score and the total points.

Your final submitted code and report should include some sample results that demonstrate that your code is successfully and correctly working. You need to present 3 samples. Due date is during the Twelfth week on Tuesday 11/05/2021, 10 am. You will need to turn-in your code source file (Soft-copy) submitted via the Moodle submission wizard below. Please use a cover page that includes your name, section number, university ID and Email address. Notes: - You must ask the user to enter the number of vertices n for your graph, and go over the source vertices or nodes in numerical or alphabetical order. Based on the number of vertices, randomly generate the edges. - Assume you are using the Adjacency Matrix to represent your graph. - Assume you have an un-directed graph.

- Need help with a c++ problem, have provided all instructions and code. I have also included the constraints, and you are allowed to use as many if statements and pointers as you want. However, you are only allowed to use one loop. Please write the code in the interQuartile method thank you. PS: Please remember, there is only one loop allowed, so if you chose to use a while loop, you can only use ONE while loop. Cannot use multiple while loops.Write a complete C++ program that implements the Breadth First Search (BFS) Algorithm (Chapter 22).

The file text.txt contains a sentence text written in all small letters and does not have any punctuation marks, no numbers, no symbols except for spaces. You are required to write a program which accepts an operation code, and zero to two inputs depending on the operation code. Based on the operation code, you will call three versions of the overlaoded function textProcessing as follows: Operation 0: The function removes all vowels from the ORIGINAL sentence. The vowels considered are the small letters (a, e, i, o, u y, and w). Operation 1: The code further asks for one lowercase letter to be input by the user. If the character is not a lower case letter, the code outputs Invalid. The function returns the distance (difference) between the letter first occurence and last occurence in the text. If the letter does not occur in the sentence, it returns 0. Operation 2: The code asks for two…
