How to make reading from `std::cin` timeout after a particular amount of time

Question

I have written a small program,

int main(int argc, char *argv[])
{
    int n;
    std::cout << \"Before reading from cin\" << std::endl;

    //          


        

Answer 1

This works for me (note that this wouldn't work under Windows though):

#include 
#include 

using namespace std;

int main(int argc, char *argv[])
{
    int n;
    cout<<"Before performing cin operation"<>n) : false;

    if(b==1)
          cout<<"input is integer for n and it's correct"<
