Redirect cin to a string

Question

I want to have cin read input from a string.

Is there a way to have it do this?

Something like this:

const char * s = \"123 ab\";
cin.readFro

In C++17, Ben Voigt's solution won't compile unless you use basic_stringbuf. Instead use the one below:

  stringbuf s;
  const char *userInput = "10 1 2 3 4 5 6 7 8 9 10 3 7";         
  s.sputn(userInput, strlen(userInput)); 
  cin.rdbuf(&s);
