At the top of this exercise on defining properties, the example Area is defined as an integer which is what you would expect i.e.
public int area;
public int Area
{
get { return area; }
set { area = value; }
}
However, further down it has become a string:
public string Area
{
get { return area; }
set
{
if (value < 0) { area = 0; }
else { area = value; }
}
}
No explanation is given for this. Please help.
