Text throbber / waiting thingy

throbber.cpp

#include <iostream>

#define SLEEP 100000 // 100 millis

using namespace std;

void throb(char in)
{
  cout << "\b" << in;
  cout.flush();
  usleep(SLEEP);
}

int main()
{
  while(true)
  {
    throb('|');
    throb('/');
    throb('-');
    throb('\\');
  }
  return 0;
}

You're gonna need to include unistd.h.
