- The function file_first_chars in python takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters. NOTE: Return the function, don't print For example: Test Result print(file_first_chars("wordlist1.txt")) hsaemCreate a new file (in Dev C++) . In Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In Lab 7, you added some functionality for a main program loop and input validation. In this lab, you will create some general purpose functions to offload some of the tasks in main(). Write functions for: displaying "hello" message displaying menu displaying "goodbye" message displaying "invalid selection" message (for invalid menu selection) displaying "invalid input" message (for divide-by-zero input validation) Prototypes should be written for each function Function definitions can be in any order, after main() Call the functions as needed in main(), replacing the original code The program should: call function to display a "hello" message before presenting the menu call function to display the menu prompt user for selection accept either uppercase or lowercase for selection call function to display error message if…In Python, Create a program that will write 100 integers created randomly in a file. The integers will be separated by a space in the file. Read the data back from the file, and display the sorted data. The program should prompt the user to enter a file name. Utilize the following function headers for this problem: Main() WriteNumbers(filename) ReadNumbers(filename) The main function will first prompt the user to enter the filename. Then the main function calls WriteNumbers-then ReadNumbers. The WriteNumbers function opens an output file and writes 100 random numbers as long a large string text. Do not use lists for this problem- please just write a random number followed by a space 100 times. The ReadNumbers function will then read the text file and display the numbers sorted. In order to sort the numbers, read the big string and then split it into a list. Now convert them into integers by using list comprehension and then sort the list. Loop through the list and print each…
- Write a C function named int getNumberOfWords( FILE* fp) which finds the number of lines in the given file. Here, assume the file is already opened in read mode and return value of fopen is assigned to fp. For example: Test Input Result printf("%d", getNumberOfWords (stdin)); aaabb124 bcdf 4 ccccccccccccc cc c c ccccddddddd dddddddddddddddddd еееееееееееееееееееее aaxx; ddfeartThis Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…Consider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = False
- C++ Khalid like to play with numbers. He has a list of numbers in a file, and he wants to split the digits of each number according to its position. Help Khalid by creating a program that does that. • You must use a function in the solution. The name of the input and output files must be as requested. . Input (string.txt) The first line contains an integer which is the number of all test cases The rest of the file contains one test case in each line. 0 Output (output.txt) For each test case, print a single line with the answer to this problem to an output file. Example 3 39 -434 100 string.txt (30,91 (-400, -30,-41 (100, 0, 0] output.txtAll I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…FOR TEST CAST 5 AND 7 Please enter the file name again or type QUIT MUST REPEAT AFTER YOU INPUT5.TXT. Hypergrade does not like this program because it says 2 out of 7 passed and Please Modify and change this program ASAP BECAUSE IT IS HOMEWORK ASSIGNMENT so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Also, for test cases 1-4 it wants only to input Please enter the file name or type QUIT to exit: then input the file and display the Total number of words. For test cases 5 and 7 it wants to only to input Please enter the file name or type QUIT to exit then input input5.txt and then display File: input5.txt does not exist.\n then display Please enter the file name again or type QUIT to exit:\n then type input1.txt to display the total number of words or type quit to exit the program. For test case 6 it wants only to Please enter the file name again or type QUIT to exit:\n then type quit to exit the porgram. import java.io.File;import…
- the code should be in python: answer all the following questions in one Python file The person running the file will be asked to choose one of these programs. A good approach to designing this file is for each question to have its own main like (main1, main2, etc.). These functions are called when the user selects a question (If the user selects question 1, main1 will be executed). code must also include comments which are explaining your code briefly. Also, make sure you specify where the question ends and the next one starts. Q1) is to write a program that allows an input of a sequence of numbers from the user and prints the number of appearances for each digit in the sequence. Below is an example of what the program should look like. Please note that the numbers that have not appeared in the sequence (such as 9) are not printed. Q2) is to write a program that allows two numbers from the user and prints all the numbers that are multiplications of three. which are within these two…You are creating a function that reads a data file and prints each line of the file. You write the following code. Line numbers are included for reference only The code attempts to read the file even if the file does not exist. SEE PHOTO You need to correct the code. Which three lines have indentation problems? Each correct answer presents part of the solution. (Choose three.) Group of answer choices Line 04 Line 03 Line 05 Line 02 Line 06 Line 07 Line 01 Line 08in c++ Create a new file (in Dev C++) In Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In Lab 7, you added some functionality for a main program loop and input validation. In this lab, you will create some general purpose functions to offload some of the tasks in main(). Write functions for: displaying a message (void) display menu and return user selection (int) prompt user for a number and return the number (int) adding (void) subtracting (void) multiplying (void) dividing (void) checking if number is 0 (bool) Prototypes must be written for each function. Definitions for each function may be in any order, after main(). Call functions as needed. Remember that functions can call other functions. If you see the same code repeating in different places, there is a good chance that a function could be used to simplify things. By now, you've gone through the thought process of how the main program loop…
