Step by step
Solved in 3 steps
- In C++ I am opening a file through a command argument and reading through it. How do you write to the file that would be opened?LANGUAGE: C++ Create a program and then: Show file input (get your input from a file) File output (output to a file) File append (add to the end of a file) Also,Try to have your code handle an error if for example you try to read from a file that doesn’t exist.C++ Language : Write a program to write the numbers from 1 to 10 in a file called "test.txt" and then read the contents of same file and display it on screen
- 1. Random numbers File: random_numbers.py (Quick note: NEVER name your files the same as a Python module. If you call this file random.py it won't let you import the real random.) (Another quick note: Don't let yourself get stuck on something for too long. If one part of one question starts taking you too long, just leave it, move on and come back to it later.) Write a complete Python program that ask the user for quantity of random numbers and a maximum, then generates and store that many numbers between 0 and the maximum. When you've got this part working, add the following interesting additions: minimum maximum random choice from existing list (Hint: if there are 7 numbers it will be a number at a random index 0-6) the list reversed* the list sorted* Note*: Python's .reverse() and .sort() list methods do NOT return the reversed or sorted list... they modify the list in place.So, if you write something like: print(numbers.sort()) You will not get what you expect. You'll sort the…Before you can read or write to a file in C, what do you need to do? Call fopen on the file Create the file Call fclose on the file Use fprintfPLEASE COMMENT CODE In a python program, create a new file and call it “ tracking”.

- Explain what are Disarium Numbers. Please provide a program in C++ language to check whether a number is Disarium or not. Attach a output file to it. Sample output: Enter a number: 175 It is a Disarium NumberIn C++, how do you encrypt one character in a file read into the code?Hi there, could you help me with this c++ hw ? with explanation please! 2.

Finally, the program reads the information from the file and displays it on the screen in the following format:Name: User's Name Phone Number: User's Phone Number Address: User's Street Address User's City, State, and Zip Code
- Which of the following is not a file-reading method in Python?a) read b) readline c) readall d) readlinesIn c programming language, read a file given a command line argument. Then print the file out with line numbers.In Python do the following: 1) Reading from Files:Suppose we have a text file (‘readfile.txt’) containing the following lines:Hello!My name is Mary Summers.This is my resume.We want to read its contents into Python. Write a code that will load the entire file into a string.Please know that when you write code to open a file, the file is assumed to be in the same directory asyour program. If it is in a different directory, then you need to specify that.
