What does the following code do? Assume this method is invoked by using Mystery ( 70, 80 ).
double dblY;
intX = intNumber1 + intNumber2;
dblY = intX / 2;
if ( dblY <= 60 )
{
lblResult.Text = "<= 60 ";
}
else
{
lblResult.Text = " Result is " + dblY;
}
} // end method Mystery
This code calculates the average of two numbers. The user is informed of the aver-age, but only if the average is above 60. In this case the two numbers entered are 70 and 80, which results in an average of 75, which will be displayed. The complete code reads:
// Average.cs

using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
