Thread: getline under Xcode on a Mac

I've been beating my head against a wall for an hour, wondering why getline was not working for my program. Pretty simple use case:

Code:

getline(cin, mystring) ;

It would work fine when I typed a single character, but when I pasted in a string, it would NOT read it in - I would get an empty string.

Then, I figured it out. Xcode must have a bug or restriction so that when you paste in a value for an input request in the Console, it ignores it. Ugg.

I didn't think the STL worked like that (getline() is looking for an array):

Code:

// istream getline
#include <iostream>
using namespace std;

int main () {
  char name[256], title[256];

  cout << "Enter your name: ";
  cin.getline (name,256);

  cout << "Enter your favourite movie: ";
  cin.getline (title,256);

  cout << name << "'s favourite movie is " << title;

  return 0;
}

Well, now you know that there is also a free function version that works for std::basic_string

Jeff, Memloop and I are using the global getline that is part of the string class. You are using the stream flavor.

See? I learn something new everyday. Most of my C++ know-how is more than 15 years old...question: at one point it was common knowledge that you did not mix malloc/free and new/delete....but now you say there is a C++ version of free() that works with strings...so is the "no-mixing" rule still valid?

Happy Holidays all..

Laserlight might have meant free, as in "no charge - you get it for free".
