How to Read an Entire Line of Text from the User in C ?

Reading an Entire Line from the User with Cin

In your provided C code, you aim to write a line of text to a file, but you encounter an issue where only one word is written instead of the entire line. The solution lies in the code's handling of user input.

The code uses cin >> y to read a character from the user, but this only captures the first character entered. To read an entire line, it's necessary to use a different approach.

Instead of cin >> y, employ the following code:

string response;
getline(cin, response);

This line uses getline to read an entire line of text from the user. The entered text will be stored in the string variable response.

Here's how to incorporate this change into your code:

char x;

cout << "Would you like to write to a file?" << endl;
cin >> x;
if (x == 'y' || x == 'Y')
{
    string response;
    cout << "What would you like to write." << endl;
    getline(cin, response);
    ofstream file;
    file.open("Characters.txt");
    file << strlen(response.c_str()) << " Characters." << endl;
    file << endl;
    file << response; // Now writes the entire line

    file.close();

    cout << "Done. \a" << endl;
}
else
{
    cout << "K, Bye." << endl;
}

By using getline to read the complete line, you can now effectively write multi-word responses to your file.
