Read a sequence of ints from cin and store them in a vector

Question

This is what I have done to read integers with std::cin and store them in a vector:

int number; 
vectorivec;

while (cin>>number)
{         


        

Answer 1

It depends on the terminal in use and the precise mechanism varies quite a lot but, conventionally, typing Ctrl+D (Linux) or Ctrl+Z (Windows) will result in an end-of-file "signal" being transmitted along the pipe, causing the EOF bit to be set on cin, and thus the next cin >> number attempt to fail.

That will break the loop.

Conveniently, the same will happen if you ran your executable with redirected input from a file. Which is kind of the point.
