Solved in 2 steps
- Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.Assume that a text file called myFile.txt contains a single line of text. Write a program that will make a copy of that file called copy.txt. c++
- Python Question: Which statement correctly opens an existing file if you want to add lines to it? A. open('data.txt', 'a') B. f = open('data.txt', 'append') C. f = open('data.txt', 'a') D. data = open('data.txt', 'w')C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found. Attached is the first lines of the .txt fileWhich method can be used to write data into a text file? A.close B.print C.exist D.rename
- Entry point for the application. Exactly zero or one command-line argume\nts are expected. * If a filename is given as an argument, then the program should print the\ contents of that * file to standard output. If a single dash (i.e., "-") is given as an arg\ument, then * the program should print the contents of standard input. * * @param args the command-line arguments */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? Group of answer choices Reads from a file Reads from a keyboard Reads from a string Writes to a screen =========== What comes first in the software development life cycle? Group of answer choices Algorithm design Identifying the problem Coding TestingA student wants to write into a file called myfile, without deleting its existing content. Which one of the following functions should he or she use? f = open('myfile', 'r') f = open('myfile', 'w+b') f = open('myfile', '+') f = open('myfile', 'a')
- Write a script named copyFile.py. This script should prompt the user for the names of two text files. The contents of the first file should be input and written to the second file. An example of the program input is shown below: Enter the input file name: copyFrom.txt Enter the output file name: copyTo.txt Output: After running the program, a file named copyTo.txt will be outputted that contains the text from the copyFrom.txt file.Which of the following statements will write to an output file, assuming that a variable oFile has been declared correctly as in the previous question and that a String variable named s has been created with the appropriate data to write? A oFile.println(s); B oFile.write(s); C oFile.output(s); D oFile.fileWrite(s);wordCount.py: Write a program that reads words from a file (filename given as a command-line argument) and prints the number of words.For example using an input: If there's a problem yo I'll solve itCheck out the hook while my DJ revolves itIce ice baby The program should print 20.
