How to read a complete line from the user using cin?

Question

Here is my current C++ code. I would like to know how to write a line of code. Would I still use cin.getline(y) or something different? I've checked, but can't find anything. When I run it, it works perfectly except it only types one word instead of the full lines I need it to output. This is what I need help with. I've outlined it in the code.

Thanks for helping

#include <iostream> #include <cstdlib> #include <cstring> #include <fstream>  using namespace std;  int main() {     char x;      cout << "Would you like to write to a file?" << endl;     cin >> x;     if (x == 'y' || x == 'Y')     {         char y[3000];         cout << "What would you like to write." << endl;         cin >> y;         ofstream file;         file.open("Characters.txt");         file << strlen(y) << " Characters." << endl;         file << endl;         file << y; // <-- HERE How do i write the full line instead of one word          file.close();           cout << "Done. \a" << endl;     }     else     {         cout << "K, Bye." << endl;     } } 

Answer 1

The code cin >> y; only reads in one word, not the whole line. To get a line, use:

string response; getline(cin, response); 

Then response will contain the contents of the entire line.
