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.

In c++ write a code that tells a user to enter a filename and read that text file line by line.

Write a C++ program: Question: Make 3 text files that includes numbers inside of them. Then ask the user which file do you want me to open and then validate the file. if the file exists you have to print the following message: "The file you requested exists, what number are you looking for?" otherwise you print the following message" "Sorry the file that you requested does not exist" if the file exists, then read the number that user enters and search in the files. if the number exists in the file, print the following message: "The number you requested is in this file." otherwise: "The number you requested does not in this file." Note: Again, do the above question without using array.

C++arrays, c-strings, functions with arrays as parameters 1. Create a file that contains 20 integers or download the attached file twenty_integers.txt Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the fileinto the array.6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array.Return the maximum value from the function (the function will be of type int).7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages.Ensure the output is readable.
