Define a macro named IS_LEAP_YEAR(year) that determines whether year is a leap year or not.

Use it in a program that accepts the year from the keyboard and outputs an appropriate

message using a switch statement.

Write a program containing the DISPLAY_VAR macro which displays, say, area3 = 20 when

invoked as DISPLAY_VAR(area, 3). Accept three values from the keyboard into the variables

area1, area2 and area3 and use the macro to display their values.
