Redirect cin to a string
c++, iostream
Solution
Like this:
#include <sstream>
#include <iostream>
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.
Problem
I want to have `cin` read input from a string. Is there a way to do this? Something like this: ``` const char * s = "123 ab"; cin.readFrom(s); // <---- I want something like this int i; cin>>i; cout<<i; //123 ```
