Question

This program will write a series of letters, starting with 'A', to an external file (letters.txt). The user will decide how many letters in total get saved to the file.

** IMPORTANT: The test cases will evaluate your code against .txt files that I uploaded. You do NOT have to upload your own txt files.

Input:

Including 'A', how many total letters would you like to store? [user types: 26]

Output (in the file, not in the console window)

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Notes and Hints:

1) Test your program with std::cout. If the correct letters show up, then delete (or comment out) that statement and switch it to the one that outputs to the file.

2) I know there are only 26 letters in the alphabet, but don't worry about the validating user's input for this basic exercise.

3) Mimir's feedback in the test cases is a bit confusing for this type of question. Pay attention to the Input and Output I wrote for you at the top of each test case.

Starter Code:

// VARIABLES
// Creating file stream object for output

// INPUT
"Including 'A', how many total letters would you like to store? ";

cout << std::endl;

// OUTPUT LETTERS TO FILE
// Create and open letters.txt for output

YOUR_CODE << ' '; // output TO FILE

C++ PROGRAM

//This program will write a series of letters, starting with 'A', 
//to an external file (letters.txt). 
//The user will decide how many letters in total get saved to the file.
#include <iostream>
#include <fstream>

using namespace std;

int main()//main function
{
        ofstream File;//ofstream used to create file.
        int totalLetters;
        File.open("letters.txt");//letters.txt file created
        cout<<"Including 'A', how many total letters would you like to store? ";
        cin>>totalLetters;//get input value from user
        for(char ch = 'A'; ch < 'A'+totalLetters; ch++)
                File << ch <<" ";//Write letters to file
        File.close();//Close file
}
