std::cout output not printed till program ends

I have a few std::cout statements and few of them do not print output to console till program ends. But it i put getchar(), it starts printing output. Why does it happen, can someone please explain?

Solution

  • The issue may be because you are not trying to flush your output. You can try like this:

    std::cout << "some text" << std::flush;

    or like

    std::cout << "some text" << std::endl;

    The standard output is buffered and on newline the buffer is flushed.
