The following program is supposed to read the length and width of a rectangle from a file named input.txt and print the area and perimeter of the rectangle to a file named output.txt. However, it fails to do so. Rewrite the program so that it accomplishes what it is intended to do. (Also, include statements to close the files and any missing code segment.) #include using namespace std; int main() { double length, width; ofstream outfile; infile.open("input.txt"); infile >> length >> width; outfile << "Area = " << length * width << ", Perimeter = " << 2 * (length + width) << endl; return 0; }

(Practice) a. Write a set of two statements declaring the following objects as ifstream objects, and then opening them as text input files: inData.txt, prices.txt, coupons.dat, and exper.dat. b. Rewrite the two statements for Exercise 2a, using a single statement.
The following program is supposed to read the length and width of a rectangle from a file named input.txt and write the area and perimeter of the numbers to a file named output.txt. However, it fails to do so. Rewrite the program so that it accomplishes what it is intended to do. (Also, include statements to close the files.#include <iostream>using namespace std;int main(){double length, width;ofstream outfile;infile.open("input.txt");infile >> length >> width;outfile << "Area = " << length * width<< ", Perimeter = " << 2 * (length + width) << endl;return 0;}
Given the following, write a code SEGMENT that does the following: Creates a string variable to store a file name (to be entered by the user) Requests the input file name from the user and stores the name in a variable Opens the input file using the entered file name Tests the STATE of the file open. If the file does not open, output a message to the user exit the program Be sure to: Include the necessary header files Declare necessary variables
You are given a filename. Read the names in the file and output only the initials. For example, if the filename is "data.txt", and the file content in "data.txt" is Dumond, Kristin Larson, Lois the output should be: KD LL
Write data to a text file file with class Formatter. Ask the user to enter an account number, first name, last name, and account balance. Make sure to provide the user with an end-of-file indicator to end input. (Using Java)
Write a program that expands on the below program by reading each line in the file, and displays all of the lines read from the file to the screen before closing it. The code for this will occur after the code that prints a message confirming that the file has been opened successfully above and before closing the file.Program should then output the number of lines in the file. Test the program by creating a text file with at least 5 lines of text (of any composition). #include<stdio.h> char c; int main (int argc, char **argv) {FILE* f; if (argc != 2) { printf("No filename in the argument");return 1;} f = fopen(argv[1], "r"); if (f == NULL) {printf("The file cannot be opened successfully: %s\n",argv[1]);return 1;} printf("The file has been opened successfully\n"); while( c != EOF) { c = fgetc(f); //read from file printf("%c",c); //display on screen } fclose(f); }

c++ program : the program will be able to show how many words in the file.txt. And be able to show the first 10 words and the number of the occurences of each word . I attached a pic there in the beginning showing how many word in a file.txt ( it's not necessary that you have to choose file with 2000 words) and then show first 10 words and how many were of them in the file. The file will contain signs and numbers as well but we will not count them. We can use the erase function . Any file or we can write a few lines there a few repated , numbers and signs like , or : or ?
Could you help me write a C++ code to do the following: Create a program that asks the user for the name of a file and thenrearranges the contents of the file so that its lines are in alphabetical order.The program should modify the file, not print its contents to the screen.Use the STL algorithm sort.
6.20 Word count (c++) Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a "word" to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.Input Notes: There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read. DO NOT USE A STRING VARIABLE.Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt.The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the program.
