Set timeout for input (cin)

Question

I'm having some trouble with setting time out for cin>>.

After 5 seconds, if the user didn't input anything, skip this cin>> and do the next line.

I tried using threads but I can't skip this cin>>. The cin thread is still running until it got an input.

I believe this should work.

#include <iostream>
#include <ctime>

int main(){
    int a;
    unsigned t0=time(0);
    std::cin >>a;
    unsigned elapsed=time(0)-t0;
    std::cout <<elapsed<<std::endl;
}

It is not the correct answer. Your code just print the time that the user spends to enter an integer. – francas Aug 17 '17 at 08:13
