A pointer is a computer science term for a variable that, instead of holding a bit of information, holds an address to where that information can be found in a computer's memory. You can imagine the variable as a signpost that \points\ to where the information can be found.
Grippe is an old fashioned word for the flu â the virus that can give you a fever, sore throat, and a headache. If you fear you're coming down with the grippe, you might spend the day in bed drinking tea. When someone feels achy, shivery, and tired, they probably fear having the grippe, which is highly contagious and sickens many people each year, mostly in the winter months. Today it's more commonly called the flu, short for influenza.
Kohlerâs disease is a rare condition in which the tarsal navicular bone (a bone in the arch of the foot) becomes inflamed. This bone disease is named after the German radiologist who described the condition in the early twentieth century. Kohlerâs disease usually affects children between the ages of three and five. It occurs more commonly in boys than in girls, and is often unilateral, affecting one foot. It is described as an avascular necrosis, or osteonecrosis, in which bone tissue deteriorates due to an interruption of blood supply.
