Question

I started out by declaring a string and storing all the text entered by the user in it. Then I transfer to a file. I cant figure out how add a line break to the input. I am just a beginner..

example code :

#include <iostream>
#include <fstream>

using namespace std;


int main()
{
    string x;
    string y;
    ofstream a_file("example.txt");
    getline ( cin , x);

    a_file<<x;
    a_file<<y;

}

Answer 1

To add a line break to the output, you need to write the string "\n" to it.

ofstream a_file("example.txt");

string line;
if (getline(cin, line)) {
  a_file << line;
  a_file << "\n";
}

It’s as simple as that. You can also combine the last two statements into one:

a_file << line << "\n";

But if you want to add the line break to the string, and not only to the file, you can do this:

string line = "some line that has been input";
line += "\n";
line += "the text of the second line, including the line break\n";
