 Draw a flowchart for a program that simulates the
doctor diagnosis. It reads a child temperature and
displays what a doctor would recommend in such
case. Doctors assume the child is healthy when his
temperature is below or exactly 37ºC. Therefore,
they recommend normal activities. However, if the
temperature is little higher than 37 ºC but still below
39 ºC, then the doctor recommends careful
observation. Otherwise, the doctors recommend that
the child should be admitted to hospital.
