Cout in loop doesn't print char by char as defined

Question

I\'ve recently started learning C++ at university and decided to advance a bit at home. I had the idea of making a program that, given a piece of text, would print out such text

Answer 1

You need flush output

 cout << text[i] << flush;

The usleep() function returns 0 on success. On error, -1 is returned, with errno set to indicate the cause of the error.

ERRORS EINTR Interrupted by a signal; see signal(7).

EINVAL usec is not smaller than 1000000. (On systems where that is considered an error.)

Answer 2

You need to flush the stream, otherwise it will be cached

cout.flush();
