Reading white spaces? oh and scanf_s

How do you get user input including white space? say, using scanf?
Oh and I can't get scanf_s to work.. it never reads properly.. weird.
And is there a way to only read a certain number of characters based on a variable?

like scanf("%%us",sizeof(string),string); but of course that looks for the input
"%us"

You should read the manual on scanf. Things like scansets, and the * modifier.... Edit: And maybe we should be in the C forum. And of course, you could read the manual on fgets just as well.

oh I'm using it in C++.. whoops.
yeah I sort of figured it out.. the MSDN entries on scanf hurt my head T_T.
I think I got it though.. using stuff like either

Code:

---

scanf("%s %s %s",...);
or
scanf("%[ ]");

i think getline method of istream class(e.g. cin is instantiation of this class) would be useful for such issue.

example from cplusplus.com

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;
}

---

yeah it is.. but actually I'm trying to get a specific number of statements, so scanf works better.
in general though, yeah getline would be better.
thanks

Why not use istream and have a comma ',' delimit each statement then do a simple string parse to get the input?

Code:

---

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

int main ()
{
    std::string name, title;

    cout << "Enter your name: ";
    std::getline(name/*, ","*/);

    cout << "Enter your favourite movie: ";
    std::cin(title/*, ","*/);

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

    return 0;
}

the space thing is working fine, but thanks for the suggestion
