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         


        

Answer 1

Like this:

#include 
#include 

std::istringstream stream("Some string 123");
streambuf* cin_backup = std::cin.rdbuf(stream.rdbuf());

You might want to back up the original rdbuf of std::cin, if you want to use it again.
