Modulus.C:
Write a program that inputs i and j and prints out
i%j.
CalcArea.C:
Write a program that inputs a, b, c and d, integer dimensions
in the following diagram, and prints out the area of the
figure.

FencePost.C:
A fence runs along an infinite line, with fence posts at
integer locations. That is, there are posts at location 3, 4, 5,
and so on. Given locations i and j, with j larger than i, how many
posts are included between i and j, including i and j.
NChooseThree.C:
Write a program which inputs integer n and outputs the integer
n (n+1) (n+2) / 3. By changing the parentheses, show how three
different answers are possible for a given n.
NChooseTwo.C:
A stair-step figure of size n is built up of 1-by-1 tiles.
Write a programing which calculates and prints the total area of
the figure for a given n. We show
by example how the figure's shape depends on n.
For n=3 the figure looks like:
